     THIS OPTION AGREEMENT ("Agreement") is made and entered into effective as
of February 14, 2000 (the "Effective Date"), by and among Atlas Precious Metals
Inc., a Nevada corporation ("APMI"), and Atlas Minerals Inc., a Colorado
corporation ("AMI"; APMI and AMI will be collectively referred to hereinafter as
"Atlas"), whose address is 370 Seventeenth Street, Suite 3010, Denver, Colorado
80202, and Seabridge Resources Inc., a company incorporated under the laws of
the Province of British Columbia, Canada ("SRI"), and Newco, a to be named U.S.
corporation to be incorporated as a wholly-owned subsidiary of SRI prior to the
Closing ("Newco"; Newco and SRI will be collectively referred to hereinafter as
"Seabridge"), whose address for purposes hereof is Suite 304, 700 West Pender
Street, Vancouver, British Columbia, Canada V6C 1G8.


                                    RECITALS
                                    --------

     A. Atlas is the owner of certain unpatented lode mining claims and
millsites located in Malheur County, Oregon, as more particularly described in
Exhibit A attached hereto and incorporated herein by reference (the "Owned
Claims"), and holds a leasehold interest in certain unpatented lode mining
claims (the "Leased Claims") and fee lands (the "Fee Lands") located in Malheur
County, Oregon, as more particularly described in Exhibit B attached hereto and
incorporated herein by reference. Atlas also holds certain additional assets in
Malheur County, Oregon, as set forth on Exhibit C attached hereto and
incorporated herein by reference (the "Additional Assets"). The Owned Claims and
the Leased Claims are collectively referred to herein as the "Claims," and the
Claims, the Fee Lands and the Additional Assets are collectively referred to
herein as the "Property."

     B. Atlas desires to grant to Seabridge, and Seabridge desires to accept
from Atlas, an exclusive option to purchase the Owned Claims and to acquire all
of Atlas' interest in the Leased Claims, the Fee Lands and the Additional
Assets, subject to the terms and conditions set forth herein.

     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants, conditions, and obligations contained herein, and other valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                                   ARTICLE I

                    GRANT OF OPTION TO PURCHASE THE PROPERTY
                    ----------------------------------------

     1.1 Grant of Option. Atlas hereby grants to Seabridge, and Seabridge hereby
accepts, an exclusive option (subject to the provisions of Sections 1.3 and 1.4)
to acquire all of Atlas' right, title and interest in and to the Property (the
"Option"), in accordance with the terms, conditions and requirements set forth
in this Agreement.

     1.2 Purchase Price.
         --------------

          (a) The purchase price (the "Purchase Price") for the purchase of the
Property to be acquired by Seabridge if it exercises the Option shall be One
Million Seven Hundred Thousand Dollars (U.S. $1,700,000), payable by delivery to
Atlas at the Closing of (i) Two Hundred Fifty Thousand Dollars (U.S. $250,000),

<PAGE>


(ii) common shares of SRI stock, no par value (the "Stock"), with an aggregate
Value (as defined below) of Seven Hundred Fifty Thousand Dollars (U.S.
$750,000); and (iii) a promissory note for Seven Hundred Thousand Dollars (U.S.
$700,000). The "Value" of a share of Stock (subject to the Value of a share not
being less than the minimum price approved by the Canadian Venture Exchange, as
provided in Section 1.2(c) below) shall be equal to the average closing price of
a share of Stock on the Canadian Venture Exchange for the 20 business days
preceding the date Seabridge exercises the Option. For purposes of determining
the Value of the Stock, the parties agree that the exchange rate to be used for
calculating the value in U.S. dollars of a share of Stock shall be the average
Canadian/U.S. dollar exchange rate listed as the "Late NY" rate in the J.P.
Morgan Index as published in the Wall Street Journal for the 20 business days
preceding the date Seabridge exercises the Option. The parties hereby agree that
except as otherwise specifically set forth in this Agreement, all references to
"Dollars" or "$" herein shall be to U.S. dollars.

          (b) If for any reason SRI is unable to deliver the Stock at the
Closing, SRI shall nonetheless be obligated to proceed with the Closing, and
agrees that it will pay an additional Seven Hundred Fifty Thousand Dollars (U.S.
$750,000) to Atlas at the Closing in lieu of the delivery of the Stock.

          (c) The parties acknowledge that the regulations governing companies
traded on the Canadian Venture Exchange establish a certain minimum price that
could be attributed to the shares of Stock (the "Minimum Price"). In the event
that the Minimum Price per share of the Stock is greater than the Value of a
share of the Stock (as calculated pursuant to Section 1.2(a) above), the parties
agree that Seabridge shall pay to Atlas in immediately available funds on the
same date that certificates representing the Stock are delivered to Atlas an
amount equal to the difference between the value of the number of shares of
Stock Atlas would have received but for the imposition of the Minimum Price and
the value of the number of shares of Stock Atlas actually receives. By way of
example (but not limitation), if the Value attributed to a share of Stock was
Cdn. $1.00, and as a result Atlas would be entitled to receive 1,120,239 shares
of Stock at the Closing (using an assumed exchange rate of $.6695 per
Cdn.$1.00), and assuming a Minimum Price of Cdn. $1.12 applied to those shares,
Atlas would actually receive only 1,000,213 shares of Stock at the Closing
(using the same assumed exchange rate). In that event, Seabridge would be
obligated to deliver an additional Cdn. $120,026 ($80,357) to Atlas at the
Closing. The parties agree that the provisions of this Section 1.2(c) shall
apply to deliveries of shares of Stock by Seabridge to Atlas pursuant to the
provision of Section 1.7(b)(iii) as well.

     1.3 Option Period. The term of the Option (the "Option Period") shall
commence upon the Effective Date, and shall continue through and including the
earlier of (a) the date the Option is exercised, (b) the date this Agreement is
terminated pursuant to Sections 7.1 or 7.2, or (c) December 31, 2001; provided,
however, that in order to maintain the Option in full force and effect Seabridge
must timely make each of the Option Payments described in Section 1.4 below.

     1.4 Option Payments. SRI agrees to timely make the following payments to
Atlas during the Option Period:

                                      -2-

<PAGE>


                 On or Before                    Amount of Payment
--------------------------------------     ------------------------------

          February 14, 2000                      U.S. $150,000   (paid)

          July 31, 2000                          U.S. $50,000

          December 31, 2000                      U.S. $100,000

          July 31, 2001                          U.S. $50,000

     None of the above-referenced payments (such payments being collectively
referred to hereinafter as the "Option Payments") shall be credited against the
Purchase Price. In addition, none of the Option Payments shall be refundable to
SRI, whether or not it exercises the Option. In the event SRI fails to timely
make any Option Payment (or any other monetary payment set forth herein), Atlas
may elect to terminate this Agreement pursuant to the provisions of Section 7.2
hereof.

     1.5 Exercise of Option. So long as it is not in default hereunder, the
Option may be exercised by Seabridge at any time on or before the expiration of
the Option Period by giving written notice of exercise to Atlas. The date on
which such notice is effectively given may be referred to as the "Exercise
Date." If Atlas has actually received such written notice on or before any of
the due dates referred to in Section 1.4, SRI will not be required to make the
Option Payment due on that date.

     1.6 Closing. The parties shall use good faith efforts to cause the Closing
to occur as soon as practicable after the Exercise Date, and in any event the
Closing of the acquisition of Atlas' interest in the Property by Seabridge shall
occur within 30 business days after the Exercise Date (not counting the Exercise
Date), at the offices of Davis, Graham & Stubbs LLP, counsel for Atlas, whose
address is Suite 4700, 370 Seventeenth Street, Denver, Colorado 80202 (the
"Closing Date"), or at such other location as the parties mutually agree.

     1.7 Deliveries at Closing. At the Closing:
         ---------------------

          (a) Atlas will deliver to Seabridge the following:

               (i) An executed and acknowledged Special Warranty Deed covering
the Owned Claims, in the form of Exhibit D hereto;

               (ii) A fully executed and acknowledged Assignment and Assumption
Agreement covering the Leased Claims and the Fee Lands, in the form of Exhibit E
hereto; and

               (iii) Certificates of Good Standing for APMI from the State of
Nevada and AMI from the State of Colorado.

          (b) Seabridge will deliver to Atlas the following:

               (i) Two Hundred Fifty Thousand Dollars (U.S. $250,000) or, in the
event the provisions of Section 1.2(b) apply, One Million Dollars (U.S.
$1,000,000), plus any additional amount required as a result of the imposition
of the Minimum Price, by wire transfer in immediately available funds;

                                      -3-

registered in names as may be designated by Atlas;

               (iii) A promissory note, in the form of Exhibit F hereto, in
favor of Atlas and evidencing the joint and several obligation of SRI and Newco
to pay Seven Hundred Thousand Dollars (U.S. $700,000) to Atlas, payable in three
equal installments of U.S. $233,333, the first installment being due and payable
6 months after the date of Closing, the second installment being due and payable
12 months after the date of Closing, and the third installment being due and
payable 18 months after the date of Closing, together with interest at a rate of
five percent (5%) per annum, payable semi-annually (such interest payable at
Seabridge's discretion either in cash or by the tender of additional shares of
Stock equivalent in value to the amount of interest then owed, such value to be
equal to (A) the average closing price of a share of Stock on the Canadian
Venture Exchange for the 20 business days preceding the date each installment is
due and payable and (B) an exchange rate (for calculating the value in U.S.
dollars of a share of Stock) equal to the average Canadian/U.S. dollar exchange
rate listed as the "Late NY" rate in the J.P. Morgan Index as published in the
Wall Street Journal for the 20 business days preceding the date each installment
is due and payable).

               (iv) A fully executed Assignment and Assumption Agreement in the
form of Exhibit E hereto;

               (v) A Deed of Trust (with Security Agreement) in the form of

security interest in the Property;

               (vi) UCC Financing Statements for filing in Malheur County,

Newco, certifying as to the adoption of resolutions of their respective Boards
of Directors approving their execution and delivery of this Agreement (or, in
the case of Newco, the agreement referred to in Section 5.1(g)) and the
performance by each of them of all of their obligations hereunder;

               (viii) A Certificate of good standing for Newco from the State of
Oregon and its state of incorporation, and similar evidence of SRI's good
standing in the Province of British Columbia; and

               (ix) Evidence reasonably satisfactory to Atlas that Seabridge has
received the consent of the Canadian Venture Exchange to the exercise of the
Option by Seabridge and the performance by Seabridge of all of its obligations
under this Agreement and any other agreements contemplated hereby.

                                   ARTICLE II

                     OTHER AGREEMENTS OF ATLAS AND SEABRIDGE
                     ---------------------------------------

     2.1 Obligation to Maintain Property.
         -------------------------------

          (a) During the Option Period, SRI shall be financially responsible for
the payment of all claim maintenance fees required to be paid to the U.S.
government in order to maintain the Claims in good standing, provided that Atlas
shall (i) prepare affidavits of such payment appropriate for recording in
Malheur County and filing with the Oregon State Office of the Bureau of Land
Management, and present those affidavits to SRI for its prompt review and
comment prior to applicable recording or filing deadlines, and (ii) actually
transmit all required payments, filings and recordings associated therewith to
the appropriate governmental agency. SRI agrees that it will provide to Atlas,
not later than August 1st of each year (or, if the deadline for making such
payments, filings and recordings changes from August 31, 30 days prior to such
new deadline), (i) a wire transfer (in accordance with written instructions to
be provided by Atlas) in the amount of the required claim maintenance fees to
maintain the Claims, and (ii) fully-executed affidavit(s) of payment of the
claim maintenance fees suitable for recording and filing with the appropriate
governmental agencies (along with sufficient filing and recording fees for the
affidavit(s), which, together with the required claim maintenance fees payable
to the U.S. government, are referred to herein as "Claim Maintenance Fees").
Atlas, if it timely receives the required amount of Claim Maintenance Fees from
SRI, shall pay such claim maintenance fees and file (with the Oregon State
Office of the Bureau of Land Management) and record (in the Malheur County Clerk
and Recorder's Office) the appropriate affidavits not later than August 10th of
each year, and provide evidence of such payment, filing and recording to SRI not
later than August 20th of each year.

          (b) During the Option Period, SRI shall be financially responsible for
making all of the advance minimum royalty payments due under the Bishop Leases
and the Sherry and Yates Lease (collectively, the "Leases") described in Exhibit
B, as set forth on the attached Schedule 2.1 (the "Lease Payments"). During the
Option Period, SRI agrees that it will provide to Atlas, at least 20 days prior
to the date any Lease Payment is due, a wire transfer (in accordance with
written instructions to be provided by Atlas) in the amount of such Lease
Payment, and Atlas, if it timely receives a Lease Payment from SRI, will pay
such Lease Payment at least 15 days prior to its due date, and provide evidence
of such payment to SRI at least 10 days prior to its due date. At SRI's request,
Atlas agrees to cooperate with SRI during the Option Period in attempting to
negotiate a reduction of the amount of advance minimum royalty payments due
under the Bishop Leases.

          (c) During the Option Period, SRI shall be financially responsible for
making all of the monthly rental payments for the Glerup office lease (as
described in Exhibit C and set forth in Schedule 2.1). Not later than the end of
the second month of each calendar quarter (February, May, August and November of
each year) during the Option Period, SRI shall forward to Atlas a wire transfer
(in accordance with written instructions to be provided by Atlas) in the amount
of monthly rental due under the office lease for the period that ends on the
earlier of (i) the expiry of the Option Period, or (ii) the end of the
subsequent calendar quarter. If such payment is timely forwarded to Atlas, Atlas
shall then be obligated to timely make the required monthly rental payment under
the Glerup office lease, and provide evidence of such payment to SRI at least 5
days prior to the end of each month.

                                      -5-

<PAGE>


          (d) Unless the Option Period ends on or before February 10, 2001,
Seabridge shall be financially responsible for the annual payments to the Oregon
Department of Geology and Mineral Industries due on February 28, 2001 in order
to maintain the exploration permits listed on Exhibit C (the "Exploration
Permits"). Not later than February 10, 2001, Seabridge shall forward to Atlas a
wire transfer (in accordance with written instructions to be provided by Atlas)
in the amount of each of those payments (as set forth on Schedule 2.1). If such
check is timely forwarded to Atlas, Atlas shall then be obligated to timely make
the required payments not later than February 15, 2001, and provide evidence of
such payment to Seabridge not later than February 20, 2001.

          (e) During the Option Period, SRI shall be financially responsible for
any annual premiums and all other costs associated with any bonds it is required
to post pursuant to the provisions of Section 2.9.

     2.2 Conduct of Operations on the Property During the Option Period.
         --------------------------------------------------------------

          (a) Operations. Subject to the requirements and restrictions of this
Section 2.2, during the Option Period, Seabridge shall have the exclusive right,
but not the obligation, to enter upon and use all or any part of the surface and
subsurface of the Property (to the extent allowed under the provisions of the
Leases), for the purposes of conducting permitting and exploration work (which
for purposes of this Agreement shall be defined as surveying, prospecting, bulk
sampling, drilling, exploring and testing for any and all ores, metals,
minerals, mineral substances and materials of every kind and character
whatsoever ("Valuable Minerals") found in, on or under the Property). Any such
activities conducted by Seabridge shall be conducted in full compliance with the
terms of the Exploration Permits, and only after (i) written notice describing
the proposed nature and scope of such activities has been delivered to Atlas,
and (ii) if necessary, the appropriate governmental agencies have approved the
conduct of such activities on the Property by Seabridge. Notwithstanding the
foregoing, during the Option Period Seabridge shall have no right to conduct any
development activities on the Property or the mining or processing or removal of
Valuable Minerals on or from the Property. In addition, during the Option
Period, Seabridge shall be entitled to evaluate the Property with regard to
title, permits, licenses, and operational and environmental compliance with
federal, state and local laws, rules and regulations. Atlas agrees that it will
make available to Seabridge, for copying at Seabridge's expense, such documents
as are in Atlas' possession and reasonably requested by Seabridge in performing
such evaluations. Seabridge shall have no obligation to begin or prosecute any
activities or operations on the Property, nor shall there be any implied
covenant so to do.

          (b) Liens and Encumbrances. During the Option Period, and thereafter
if Seabridge does not exercise the Option, or until the Purchase Price is paid
in full if Seabridge exercises the Option, Seabridge shall keep the title to the
Property free and clear of liens and encumbrances resulting from its operations
hereunder, provided that Seabridge may refuse to pay any claims asserted against
it which it disputes in good faith, and provided further that Seabridge shall,
upon written request by Atlas, comply with any statute which permits the removal

                                      -6-

<PAGE>


of such lien upon furnishing a bond or other security. At its sole cost and
expense, Seabridge shall promptly contest any suit commenced to enforce such a
claim and, if the suit is decided against Seabridge, shall promptly pay the
judgment and shall post any bond and take all other action necessary to prevent
any sale of the Property, or any part thereof.

          (c) Reclamation. Seabridge, if it does not exercise the Option, shall
reclaim the surface of the Property disturbed by it (or on its behalf) during
the Option Period in accordance with applicable governmental regulations and
shall, within a reasonable time period after the completion of such reclamation,
obtain written approval from the appropriate governmental agency that such
completion is satisfactory. Further, if it does not exercise the Option,
Seabridge shall remove all hazardous substances (as that term is defined in "
101(14) of the Comprehensive Environmental Response, Compensation and Liability
Act, 42 U.S.C. " 9601 et seq.) from the surface of the Property that Seabridge
has deposited (or has had deposited on its behalf) on the Property during the
Option Period. For a period of one year following the earlier of the end of the
Option Period or an election by Seabridge not to exercise the Option, Atlas
shall grant Seabridge reasonable access to the Property as necessary for the
performance of such required reclamation and removal of hazardous substances.
Seabridge shall complete all such reclamation and removal as expeditiously as
reasonably practicable.

          (d) Governmental Permits. To the extent it may legally do so, Atlas
hereby grants to Seabridge the right to conduct operations on the Property
during the Option Period (subject to the limitations set forth in Section 2.2
(a)) pursuant to the Exploration Permits and any and all other federal, state or
local governmental permits, licenses and other approvals currently in place;
provided, however, that Atlas makes no representation or warranty as to whether
applicable governmental authorities will allow Seabridge to conduct any
activities or operations on the Property pursuant to the Exploration Permits or
otherwise, or that the applicable authorities will allow the Exploration Permits
to remain in place during the Option Period. Atlas agrees to cooperate with
Seabridge in good faith to keep the Exploration Permits in place during the
Option Period. Seabridge shall also have the right and authority to apply, in
the name of Seabridge, for all necessary permits, licenses and other approvals
from the United States of America, the State of Oregon or from county or local
authorities. Seabridge agrees that it will not disturb the surface of the
Property without obtaining all required permits, licenses, consents and
approvals. If it does not exercise the Option, Seabridge, to the extent it may
legally do so, will transfer to Atlas, at the request of Atlas, all federal,
state and local permits, licenses and approvals pursuant to which Seabridge
conducted activities on the Property during the Option Period. Any such transfer
to Atlas will not relieve Seabridge of its obligations under this Section 2.2.

          (e) Compliance with Laws. Seabridge agrees to conduct all of its
activities and operations on the Property in accordance with good and minerlike
practices and in compliance with all applicable laws, rules and regulations of
the United States, the State of Oregon and any department or political
subdivision thereof having jurisdiction in the matter, including without
limitation, the Exploration Permits, and such laws, rules and regulations
pertaining to social security, unemployment compensation, wages and hours and
conditions of labor, the environment, human health and safety and reclamation,
and Seabridge shall defend, indemnify and hold Atlas, its officers, directors,
successors and assigns harmless from and against payment of any damages
occasioned by Seabridge's failure to comply with said laws.

     2.3 Maintenance. During the Option Period and in accordance with the
provisions of the Leases, except as otherwise set forth in Section 2.1 and
except as otherwise provided in the Leases, Newco shall have the full, exclusive
right to relocate or amend (in the name of Atlas) any or all of the Claims, and,
with the prior written consent of Atlas, which consent shall not be unreasonably
withheld, to abandon, apply for mineral patents, defend contests or adverse
suits and negotiate settlement thereof with respect to any and all of the
Claims. Notwithstanding the foregoing, if during the Option Period Seabridge
desires to abandon any of the Leased Claims (to the extent allowed by the
Leases), Seabridge shall provide Atlas with at least 45 days prior written
notice of such intention. If Seabridge exercises the Option, Newco shall at its
expense promptly after the Closing file a good and sufficient notice of transfer
of interest covering the Claims with the Oregon State Office of the Bureau of
Land Management.

     2.4 Information and Data. Upon execution of this Agreement, Atlas shall
make available to Seabridge for copying at Seabridge's expense all records, data
and information in Atlas' possession relating to title to the Property, and all
maps, surveys, technical reports, drill logs, mine, mill and smelter records,
and all metallurgical, geological, geophysical, geochemical and other technical
data pertaining to the Property in its possession; provided, however that Atlas
makes no representation or warranty as to the reliability, accuracy or
completeness of any such information or data, including without limitation any
information and data provided to Seabridge pursuant to the provisions of Section
2.2(a), and Seabridge shall rely on the same at its sole risk. Seabridge shall
use such information and data solely for the purpose of evaluating the Property
with a view to exercising the Option and Seabridge shall not use the information
or data or permit its use for any other purpose. All such information and data
made available by Atlas shall be returned to Atlas by Seabridge promptly upon
termination of this Agreement if Seabridge does not exercise the Option. In
addition, Seabridge shall turn over to Atlas in the event of such termination
any data and information pertaining to the Property generated by or on behalf of
Seabridge during the Option Period.

     2.5 Indemnity. Except as to damages sustained by Atlas while on the
Property pursuant to Section 2.7, Seabridge agrees to defend, indemnify and hold
Atlas, its officers, directors, successors and assigns harmless from and against
any loss, liability, expense or damage (including reasonable attorneys' fees and
disbursements) Atlas may incur to third persons or other entities for injury to
or death of persons or damage to property which is the result of Seabridge
conducting any operations at or on the Property during the Option Period. 2.6
Insurance. Seabridge agrees to carry such insurance, covering all persons
working at or on the Property for Seabridge, as will fully comply with the
requirements of all applicable federal laws, rules or regulations and the
statutes of the State of Oregon pertaining to worker's compensation and
occupational disease and disabilities as are now in force or as may be hereafter
amended or enacted. In addition, during the Option Period, Seabridge agrees to
carry liability insurance with respect to its operations at the Property in
reasonable amounts in accordance with accepted industry practices. Any liability
insurance policies maintained by Seabridge pursuant to this Section 2.6 shall
name Atlas as an additional insured, and Seabridge shall provide Atlas with
evidence of such insurance prior to conducting any activities at or on the
Property.

     2.7 Inspection. During the Option Period, Atlas and its authorized agents,
at Atlas' sole risk and expense, shall have the right, exercisable during
regular business hours, at a mutually convenient time, in compliance with
Seabridge's safety rules and regulations, and in a reasonable manner so as not
to interfere with Seabridge's operations, to go upon the Property for the
purpose of confirming that Seabridge is conducting its operations in the manner
required by this Agreement. Atlas shall defend, indemnify and hold Seabridge,
its officers, directors, successors and assigns harmless from all claims for
damages arising out of any death, personal injury or property damage sustained
by Atlas, its agents or employees, while in or upon the Property pursuant to
this Section 2.7, unless such death, injury or damage is due to Seabridge's
wrongful conduct.

     2.8 Taxes. During the Option Period, Seabridge shall be responsible for
payment of all taxes levied or assessed upon or against the Property and any
facilities or improvements located thereon; provided, however, that Seabridge
shall not be responsible for any such payments for which Atlas receives notices
of due dates and fails to timely forward copies of such notices to Seabridge. In
the event it exercises the Option, Seabridge shall pay any sales and use taxes
and real property transfer taxes imposed on the transfer of the Property from
Atlas to Newco.

     2.9 Replacement of Bonds. In accordance with that Second Amended Plan of
Reorganization for Atlas Corporation dated January 10, 2000, and that Second
Amended Plan of Reorganization for Atlas Precious Metals Inc. dated January 10,
2000, both approved by the United States Bankruptcy Court for the District of
Colorado (collectively, the "Plan of Reorganization"), Atlas' reclamation
obligations pertaining to the Property are limited to the amounts set forth in
the existing bonds identified on Exhibit C (the "Existing Bonds"). As to
operations or activities on the Property undertaken by or on behalf of Atlas,
the relevant governmental agencies are limited to calling the Existing Bonds and
taking action against the Surety Company that issued those bonds in the event
the reclamation obligations currently required thereunder are not timely
performed. The parties acknowledge and agree that Atlas makes no covenant,
representation or warranty as to whether the Existing Bonds will remain in place
during the Option Period, although Atlas will use good faith efforts to take no
actions to cause those bonds to be released, and will cooperate in good faith
with Seabridge in an effort to have the amount of the Existing Bonds reduced.
Prior to the Closing Date, Seabridge shall make arrangements with a
nationally-recognized surety company to issue reclamation bonds (the
"Replacement Bonds") as required to replace the Existing Bonds, and Seabridge
shall provide evidence of such arrangements as is reasonably acceptable to
Atlas. Seabridge shall use its best efforts to arrange for the release of the
Existing Bonds and the acceptance by the appropriate governmental authorities of
the Replacement Bonds as soon as practicable and in any event not later than 21
days after the Closing. After the Closing and until the Replacement Bonds are in
place, Seabridge agrees that it will not conduct any activities that disturb the
surface of the Property or otherwise take any actions that could increase the
amount of expenditures required to reclaim the Property. Prior to the end of
such 21-day period, Atlas agrees that it will not take any final actions to
obtain the release of the Existing Bonds. Seabridge agrees to defend, indemnify
and hold harmless Atlas, its officers, directors, successors and assigns from
and against any and all liabilities, claims, damages, losses or expenses
(including interest and penalties, reasonable attorneys' fees, and other
reasonable expenses of defending any actions relating thereto) arising from or

                                      -9-

<PAGE>


related to the failure to timely obtain the release of the Existing Bonds or any
actions taken by any governmental authority affecting any Existing Bond as a
result of such failure. In addition, Seabridge agrees that before it undertakes
any activities or operations at the Property during the Option Period that would
require an increase in the amount of expenditures required to reclaim the
Property, it will at its sole expense post such bonds as are required before
commencing any such activities or operations, and those bonds will be the
primary bonds for such disturbances.

and in good standing and full force and effect is limited to its knowledge).

               (ii) With respect to the Owned Claims that were originally
located by Atlas, subject to the paramount title of the United States and the

filings required to maintain those Owned Claims in good standing have been

agencies; provided, however, that to the extent that and during any periods of
time those Owned Claims were subject to any agreement by which Atlas had
conveyed any interest in those Owned Claims to any third party, and as a result
a third party was responsible for maintaining those Owned Claims, each of the
foregoing representations and warranties is limited to Atlas' knowledge. In
addition, Atlas represents and warrants that those Owned Claims are free and
clear of all liens, claims and encumbrances in favor of third parties and
arising by, through or under Atlas.

               (iii) With respect to the Leased Claims and any of the Owned

Development Act of 1954 and the Surface Resources and Multiple Use Act of 1955,

1, 1992; (B) since API acquired an interest in those claims, claim rental and
maintenance fees required to be paid under federal law to maintain those claims

               (iv) Nothing in this Section 3.1(e) shall be deemed to be a
representation or warranty by Atlas that any of the Claims contains a discovery
of valuable minerals. In addition, Atlas makes no representations or warranties
whatsoever with respect to (A) the existence (or non-existence) of any overlaps
or conflicts between the Claims and unpatented or patented mining claims owned
by third parties, (B) whether the land on which any of the millsites comprising
a portion of the Claims is non-mineral in character or whether any of those
millsites are being used or occupied for mining purposes as required by law, or
(C) whether the use of all or any of the millsites would be approved as part of
a proposed plan of operations for activities on the Claims, or (D) the validity,
adequacy or amount of any water rights covered by the Water Permit described in
Exhibit C.

               (v) The parties hereby acknowledge and agree that certain of the
Leased Claims, as described in Part III of Exhibit B, are claims that were
located by Atlas pursuant to the terms of the Sherry and Yates Lease, and that
the locator or owner of those claims is obligated to convey those claims to the
lessors under that lease.

          (f) Legality. To Atlas' knowledge, any activities on the Property
conducted by Atlas or any third party to whom Atlas conveyed any interest in the
Property were not in material violation of any law, rule, ordinance, or other
governmental regulation, including, without limitation, those relating to
zoning, condemnation, mining, reclamation, environmental matters, equal
employment, and federal, state, or local health and safety laws, rules, and
regulations, the lack of compliance with which could materially adversely affect
the Property.

          (g) Litigation and Claims. To Atlas' knowledge, there are no actions,
suits or proceedings pending or threatened against or affecting the Property,
including any actions, suits, or proceedings being prosecuted by any federal,
state, or local department, commission, board, bureau, agency, or
instrumentality. To its knowledge, Atlas is not subject to any order, writ,
injunction, judgment, or decree of any court or any federal, state, or local
department, commission, board, bureau, agency, or instrumentality which relates
to the Property.

          (h) Consents. Except as required under the Exploration Permits or any
other governmental permit or approval pertaining to the Property, Atlas has
obtained all consents, approvals, authorizations, declarations, or filings
required by any federal, state, local, or other authority, or any lenders,
creditors, and other third parties in connection with the valid execution,
delivery, and performance of this Agreement and the consummation of the
transaction contemplated hereby. The Leases do not require any consent for Atlas
to convey or assign its interests thereunder.

          (i) Existing Bonds. To Atlas' knowledge, the amount of the Existing
Bonds is sufficient to cover the existing reclamation obligations pertaining to
the Property as set forth in the Exploration Permits (using current cost and
pricing assumptions).

          (j) Brokerage or Finder's Fee. The parties acknowledge that a finder's
fee is owed to Geographe MFS International, Inc. by Atlas, and that payment of
that fee shall be Atlas' sole obligation.

          (k) Representations. To the knowledge of Atlas, no statements,
warranties, or representations made by it herein contain any untrue statement of
a material fact or omit to state a material fact necessary in order to make the
statements made, in light of the circumstances under which such statements were
or will be made, not misleading.

hereby, have been taken. This Agreement and all agreements and instruments
contemplated hereby, when executed and delivered by SRI, will be the legal,
valid, and binding obligations of SRI enforceable against SRI in accordance with
their terms. The execution, delivery and performance of this Agreement will not
violate any provision of law; any order of any court or other agency of
government; or any provision of any indenture, agreement or other instrument to
which SRI is a party or by which its properties or assets are bound; or be in
conflict with, result in a breach of or constitute (with due notice and lapse of

          (e) Consents. SRI has obtained all consents, approvals,
authorizations, declarations, or filings required by any federal, state, local,
or other authority (except the Canadian Venture Exchange), or any lenders,
creditors, and other third parties in connection with the valid execution,
delivery, and performance of this Agreement and the consummation of the
transaction contemplated hereby.

          (f) Brokerage or Finder's Fee. All negotiations relative to this
Agreement and the transactions contemplated hereby have been carried on by SRI
in such manner as not to give rise to any valid claim against Atlas for a
brokerage commission, finder's fee or other fee or commission arising by reason
of the transactions contemplated by this Agreement.

          (g) The Stock. On the date of this Agreement, the authorized capital
stock of SRI consists of 9,497,367 common shares without par value, none of
which are held by SRI. The Stock has been duly authorized for issuance and
reserved therefor and, when issued, all shares of the Stock shall be validly
issued, fully paid and nonassessable shares of capital stock of Seabridge, free
and clear of all liens, charges and encumbrances. There does not exist any
preemptive right in favor of any person with respect to the Stock. When issued,

statements of cash flow for the fiscal year then ended. Such financial
statements and the notes thereto were prepared in accordance with Canadian
generally accepted accounting principles and fairly present the financial
condition and results of operations of SRI at the date and for the periods
covered thereby all in accordance with Canadian generally accepted accounting
principles consistently applied. Neither the financial statements nor the
related statements contained as of their respective dates, any untrue statement
of a material fact or any omission to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The balance sheets
included in the financial statements (including any related notes) present
fairly in all material respects the financial position of SRI as of their
respective dates and the results of operations, changes in financial position,
cash flows and changes in stockholders' equity, as the case may be, of SRI for
the periods therein set forth.

action or administrative action or any other type of action or proceeding (an
"Action") or promptly after either of them, to their respective knowledge, shall
become subject to, or possess actual knowledge of, any damage, liability, loss,
cost, expense, or claim to which the indemnification provisions of this

                                      -19-

<PAGE>


Agreement (including but not limited to Sections 6.1 or 6.2) relate, whether
based on a third party claim or otherwise, shall give written notice to the
other party setting forth the facts relating to the claim, damage, or loss, if
available, and the estimated amount of the same. "Promptly" shall mean giving
notice within five business days; provided, however, that failure to give any
such notice promptly shall not relieve the indemnifying party of any liability
hereunder unless it is materially prejudiced thereby. Upon receipt of such
notice relating to an Action, the indemnifying party shall be entitled to (a)
participate at its own expense in the defense or investigation of any claim or
Action or (b) assume the defense thereof, in which event the indemnifying party
shall not be liable to the indemnified party for legal or attorney fees
thereafter incurred by such indemnified party in defense of such action or
claim; provided, that if the indemnified party may have any unindemnified
liability out of such claim, such party shall have the right to approve the
counsel selected by the indemnifying party, which approval shall not be withheld
unreasonably. If the indemnifying party assumes the defense of any claim or
Action, all costs of defense of such claim or Action shall thereafter be borne
by such party and such party shall have the authority to compromise and settle
such claim or Action, or to appeal any adverse judgment or ruling with the cost
of such appeal to be paid by such party; provided, however, if the indemnified
party may have any unindemnified liability arising out of such claim or Action
the indemnifying party shall have the authority to compromise and settle each
such claim or Action only with the written consent of the indemnified party,
which shall not be withheld unreasonably, and if such consent is withheld, the
indemnifying party shall not be responsible for any costs, fees or expenses
incurred by the indemnified party in excess of the proposed settlement amount
(with respect to the indemnified amount of such claim or action). The
indemnified party may continue to participate in any litigation at its expense
after the indemnifying party assumes the defense of such Action. In the event
the indemnifying party does not elect to assume the defense of a claim or
Action, the indemnified party shall have authority to compromise and settle such
claim or Action only with the written consent of the indemnifying party, which
consent shall not be unreasonably withheld, or to appeal any adverse judgment or
ruling, with all costs, fees, and expenses indemnifiable under Sections 6.1 or
6.2 hereof to be paid by the indemnifying party.

     6.4 Nature of Indemnification. The parties hereby agree that their
respective indemnification obligations set forth in Sections 6.1 and 6.2 are to
be deemed complementary with and supplemental to any specific indemnification
obligations set forth elsewhere in this Agreement, that those specific
indemnification obligations set forth elsewhere in this Agreement shall not be
deemed to limit or restrict the indemnification obligations set forth in
Sections 6.1 and 6.2, and that the indemnification obligations set forth in
Sections 6.1 and 6.2 shall not be deemed to limit or restrict the specific
indemnification obligations set forth elsewhere in this Agreement.

                                  ARTICLE VII

                                  TERMINATION
                                  -----------

     7.1 Termination by SRI. SRI shall have the right to terminate, surrender
and relinquish this Agreement at any time during the Option Period by giving
written notice to Atlas of such election. If Seabridge does not exercise the
Option during the Option Period, this Agreement will terminate automatically.
Any termination by Seabridge pursuant to this Section 7.1 will be effective when

                                      -20-

<PAGE>


such notice is effective as provided in Section 8.1 below. Upon termination of
this Agreement pursuant to this Section 7.1, Seabridge shall have no further
liability or obligations hereunder or with respect to the Property, except with
respect to the obligations set forth in this Section 7.1 and Sections 2.1,
2.2(b)-(e), 2.4, 2.5, 2.8, 2.9, 6.2, 6.3, 6.4, 7.3, 7.4 and 7.5.

     7.2 Termination by Atlas. In the event of a default hereunder on the part
of Seabridge, Atlas shall give to Seabridge written notice specifying the
particular default or defaults asserted, and Seabridge shall have 30 days after
the receipt of said notice within which either to cure such specified defaults,
or to undertake to cure the same and diligently thereafter promptly to cure the
same; provided, however, that in the event of a default by Seabridge in timely
making and satisfying the full amount of any monetary payment required under
this Agreement, Atlas may elect to terminate this Agreement immediately without
providing notice of such a default to Seabridge and without any cure period. In
the event Seabridge cures a default (other than monetary defaults, for which
there is no cure) as set forth above, this Agreement shall continue in full
force and effect as though no default has occurred. In the event such curative
action is not so completed or diligent efforts to cure such defaults are not
undertaken within the applicable 30-day period and thereafter diligently pursued
to completion, or if the nature of the default gives Atlas the right to
immediately terminate this Agreement as set forth above, Atlas may elect to
terminate this Agreement by notice to Seabridge as provided in Section 8.1. Upon
termination of this Agreement pursuant to this Section 7.2, Seabridge shall have
no further liability or obligations hereunder or with respect to the Property,
except with respect to the obligations set forth in this Section 7.2 and
Sections 2.1, 2.2(b)-(e), 2.4, 2.5, 2.8, 2.9, 6.2, 6.3, 6.4, 7.3, 7.4 and 7.5.

     7.3 Release. Upon termination of this Agreement, if Seabridge has not
exercised the Option, Seabridge will, at the written request of Atlas, provide
Atlas with a written release, in recordable form, of its rights hereunder with
respect to the Property.

     7.4 Surrender of Possession and Removal of Equipment. Upon termination of
this Agreement, if Seabridge has not exercised the Option, Seabridge shall
surrender possession of the Property, subject to the condition that Seabridge
shall have the right at any time within one year after such surrender or
termination of this Agreement to remove all of its tools, equipment, machinery,
supplies, fixtures, buildings, structures and other property erected or placed
on such property by Seabridge, excepting only timber, chutes and ladders in
place for underground support and entry. Title to such property not removed
within one year shall, at the election of Atlas, pass to Atlas. Alternatively,
at the end of one year Atlas may remove any such property from the Property and
dispose of the same in a commercially reasonable manner, all at the expense of
Seabridge.

     7.5 Exercise of Option. The provisions of Sections 1.2, 1.6, 1.7, 2.1,
2.2(b), 2.2(e), 2.5, 2.7, 2.9, 3.1, 4.1, 4.2, 6.1, 6.2, 6.3, 6.4, and Article
VIII of this Agreement shall survive the Closing of the Option. In the event the
Closing of the transactions contemplated under Articles I and II does not occur
as the result of a failure of a condition precedent set forth in Section 5.1 or
5.2, the provisions of Sections 2.1, 2.2(b)-(e), 2.4, 2.5, 2.8, 2.9, 6.2, 6.3
and 6.4 shall survive.
