4.7

Acknowledgements by National Gold and ONCM.  National Gold and ONCM acknowledge and agree that:

(1)

ONCM is purchasing the Assets on an “as is, where is” basis except as expressly stated herein and that they have been afforded full opportunity by MSA to conduct due diligence investigations in respect of MSA, the Concessions, the Mulatos Project, the Ejido Action, the environmental liabilities associated with the Mulatos Project, the Ejido Agreements, the Environmental Permits and the purchase and sale of the Assets and that it is satisfied with the result of those investigations including without limitation as to the continuing existence, availability, enforceability or assignability of the foregoing.  In particular, the following material issues have been identified by MSA to ONCM and ONCM has conducted sufficient investigations in respect of the following matters to assume all liabilities in respect thereof:

(a)

Acid Rock Drainage/Acid Mine Drainage: The Mulatos Project area contains known occurrences of acid rock drainage and acid mine drainage, which occur naturally and as a result of manmade activities, which include historic mining activities.  MSA has collected surface water and groundwater samples, which show both surface and groundwater in the Mulatos Project area have been negatively impacted through the addition of heavy metals, reduction of pH and degradation of other water quality criteria routinely measured to assess water quality.  Acid rock drainage and acid mine drainage has or may have an impact on surface water, groundwater, flora, fauna, fisheries, land productivity for agriculture or ranching use and visual esthetics.

(b)

Historic Mining and Exploration Activities: The Mulatos Project area contains surface and underground disturbances to the natural environment that were caused as a result of historic mining and exploration activities.  Disturbances include road construction, drilling, mining, tailing disposal, underground excavation, waste pile creation as a result of underground excavation and mining and building construction to support exploration activities.  Some historic processing activities are known to have used cyanide.  Artisan miners in the Mulatos Project area use and have used mercury to recover precious metals from their mining activities.  These disturbances have or may have an impact on flora, fauna, fisheries, surface water, ground water, land productivity for agriculture or ranching use and visual esthetics.

(c)

Exploration Activities: The Mulatos Project area contains surface and underground disturbances to the natural environment that were caused as a result of exploration activities.  Disturbances include road construction, drilling, underground excavation, waste pile creation as a result of underground excavation, building construction to support exploration activities and operation of man camps to house workers performing exploration and engineering activities.  These disturbances have or may have an impact on flora, fauna, fisheries, surface water, ground water, land productivity for agriculture or ranching use and visual esthetics.

(d)

Soil Erosion: Surface disturbances on the Mulatos Project site resulting from historic mining activities and recent exploration activities contribute to increased soil erosion.  These disturbances have or may have an impact on flora, fauna, fisheries, surface, ground water, land productivity for agriculture or ranching use and visual esthetics.

(e)

Endangered Species:  Endangered species of fish and plants have been identified in the area of the Mulatos Project.  The presence of these endangered species may adversely impact the ability of ONCM to conduct exploration and development of the Mulatos Project and to obtain regulatory approval for its activities.

(2)

purchase of Assets under this Agreement may not include certain permits, authorizations, consents and ownership interests in respect of environmental matters, use of explosives, water rights and access and surface use rights which may be required by ONCM in order to derive all or any benefit from the Assets purchased hereunder;

(3)

MSA holds Environmental Permits and other permits, consents and approvals required for the exploration, exploitation, use and development of the Mulatos Project, including the following:

(a)

the expired and non-transferable Resolution No. 498, dated October 24, 1994 to the Mulatos Project (“Cerro La Estrella” area) from SEMARNAP, Mexico;

(b)

the expired and non-transferable Resolution No. 699, dated March 13, 1995 to the Mulatos extension (“Halcon-Yaqui” area) from SEMARNAP, Mexico;

(c)

the expired and non-transferable Resolution No. 108, dated August 21, 1997 to Mulatos and La Escondida area from SEMARNAP, Sonora;

(d)

Resolution of the Manifestación Impacto Ambiental;

(e)

Cambio de Uso de Suelo; and

(f)

any extensions, renewals or amendments of the foregoing.

National Gold and ONCM shall be responsible for determining, as part of their legal due diligence, and MSA makes no representation or warranty as to, the transferability or assignability of the Environmental Permits, the ability of the Parties to obtain the consent or approval of any Agency to the transfer or assignment of the Environmental Permits, or the ability to have such transfer or assignment recognized by any Agency.  Although MSA believes the Resolution of the Manifestación Impacto Ambiental and the Cambio de Uso de Suelo to be transferable, National Gold and ONCM expressly acknowledge that the Environmental Permits and other permits, consents and approvals may not be transferable or assignable.  MSA shall not be liable to National Gold or ONCM for damages, loss, claims, liabilities or a reduction in the Purchase Price should such transfer or assignment not be possible.  ONCM shall be responsible for notifying and obtaining the consent of any Agency required under Applicable Law;

(4)

Either before or after Closing MSA may assign to other parties (“Assignees”) some or all of the benefits derived by MSA under this Agreement, or any document or instrument contemplated hereby, including the Debentures, the Promissory Notes and the RTE.  National Gold and ONCM further acknowledge and agree that any Assignee of an interest of MSA hereunder will have all of the rights and privileges of MSA under this Agreement as if it was a party hereto.  In furtherance of any such assignment MSA may request that ONCM deliver at Closing one or more Promissory Notes or Debentures in such denominations and in either Canadian or United States currency (at a fixed exchange rate) as may be directed by MSA prior to Closing.  MSA may request that any document or instrument to be delivered by National Gold or ONCM at Closing be registered in the name of and delivered to an Assignee of MSA; and

PROMISSORY NOTE

$750,000

[Closing Date]

FOR VALUE RECEIVED, the undersigned O.N.C. de Mexico S.A. de C.V., a Mexican corporation (“ONCM”) whose address is ·, unconditionally promises to pay to the order of Minera San Augusto, S.A. de C.V. (the “Holder”) at ·, or at such other place as the Holder of this Note may from time to time designate in writing, without deduction or setoff, in lawful money of Canada, the principal sum of $750,000 (the “Principal Amount”), together with interest, if any, on such Principal Amount and any other amounts due under this Note.

1.

Payment.  Subject to Section 8 of this Note, ONCM shall pay to the Holder $750,000 on ·, 2001 [180 days after Closing] (the “Due Date”).  The Principal Amount may be prepaid in whole or in part at any time without premium or penalty.  Unless the Holder shall otherwise elect, each payment made under this Note shall be applied first to costs and expenses incurred in connection with the enforcement of this Note, next to interest accrued under this Note, if any, and any balance shall be applied to reduce the Principal Amount of this Note.

2.

Late or Partial Payments.  The acceptance by the Holder of any payment that is less than the entire amount then due under this Note shall be on account only and shall not constitute a waiver of the obligation of ONCM to pay such entire amount.  The failure of ONCM to pay the entire amount then due under this Note shall be and continue to be an event of default under this Note, notwithstanding the acceptance by the Holder of less than such entire amount on account, and the Holder shall thereafter, until such entire amount is paid (and notwithstanding acceptance by the Holder thereafter of further sums on account or otherwise), be entitled to exercise all rights and remedies provided for in this Note on the occurrence of an event of default under this Note.  The acceptance by the Holder of any amount due under this Note after the same is due shall not constitute a waiver of the right to require prompt payment, when due, of all other amounts due under this Note or to declare that an event of default has occurred under this Note with respect to any other amount not paid when due.

3.

Default.  Subject to Section  of this Note, if any payment required under this Note is not made when due, the entire unpaid Principal Amount of this Note, together with any other amount due under this Note, shall, at the option of the Holder, become due and payable without presentment, demand, protest or notice of any kind, all of which are expressly waived by ONCM and all endorsers, guarantors, sureties, accommodation parties and other persons at any time liable for all or any portion of the indebtedness evidenced by this Note, and shall thereafter earn interest, both before and after judgment, at a nominal rate (the “Default Rate”) of 12 percent per annum with interest upon overdue interest at the same rate.  Any forbearance, failure or delay by the Holder in exercising any right or remedy under this Note or otherwise available to the Holder shall not be deemed to be a waiver of such right or remedy, nor shall any single or partial exercise of any right or remedy preclude the further exercise of such right or remedy.  ONCM shall pay all costs and expenses incurred by the Holder in connection with the enforcement of this Note (regardless of the particular nature of such costs and expenses and whether incurred before or after the initiation of suit or before or after judgment), including, without limitation, court costs and trustee’s and attorneys’ fees and costs.

4.

Security.  This Note is secured by a security agreement and Blanket Guarantee issued pursuant to the terms of an Asset Purchase Agreement dated as of the date hereof between ONCM, the Holder and National Gold Corporation (the “Asset Purchase Agreement”) and the documents, agreements, certificates and instruments contemplated therein creating a lien and/or security interest on certain real and personal property rights and interests of ONCM hereof, all as contemplated in the said Asset Purchase Agreement and ancillary documents, as they may be modified or amended from time to time.

5.

Usury.  Notwithstanding any other provision contained in this Note, in the Asset Purchase Agreement or in any other agreement entered into in connection with this Note, if the Holder ever receives as interest under this Note or the Asset Purchase Agreement an amount which would result in interest being charged at a rate exceeding the maximum allowed by law, such amount or portion as would otherwise be excessive interest shall automatically be applied toward reduction of the unpaid Principal Amount then outstanding under this Note, and not toward the payment of interest.

6.

Assignment.  The Holder may assign or transfer all or any part of the Holder’s rights or obligations under this Note and on request of the Holder ONCM shall issue and deliver new promissory notes having the same terms and conditions as this Note (the “Replacement Notes”) except that the principal amount under the Replacement Notes shall equal in the aggregate the principal amount outstanding under this Note.  ONCM may not assign or transfer, whether absolutely, by way of security or otherwise, all or any part of ONCM’s rights or obligations under this Agreement without the Holder’s prior written consent.

7.

Miscellaneous.  ONCM and all endorsers, guarantors, sureties, accommodation parties and other persons at any time liable for all or any portion of the indebtedness evidenced by this Note consent to all extensions of time, renewals, waivers or modifications that may be granted by the Holder with respect to the payment or other provisions of this Note, the release of all or any portion of any security given in connection with this Note, with or without substitution, and the release of any party liable under this Note.  Time is of the essence with respect to all obligations of ONCM under this Note.  The unenforceability or invalidity of any provisions of this Note shall not affect the enforceability or validity of any other provision of this Note.  The terms of this Note shall bind ONCM and inure to the benefit of the Holder.  This Note shall be governed by British Columbia law.  This Note, the Asset Purchase Agreement and any other written agreement entered into in connection with this Note are the final expression of the agreement between the Holder and ONCM and may not be contradicted by evidence of any alleged oral agreement.

8.

Grace Period.  In the event that ONCM: (a) has not received a refund of the IVA Payment (as defined in the Asset Purchase Agreement) on or before the Due Date, and (b) ONCM has diligently used all reasonable commercial efforts to obtain a refund of the IVA Payment on or before the Due Date, then the Due Date shall be extended to the date which is the earlier of 60 days after the Due Date and the date which is 3 Business Days (as defined in the Asset Purchase Agreement) after the date that the IVA Payment is received by ONCM and interest at 12% per annum shall accrue or be payable during such extended period.

9.

Conflicts.  In the event of a conflict between the provisions of this Note and the provisions of the Asset Purchase Agreement, the Asset Purchase Agreement shall prevail.

FOR VALUE RECEIVED, the undersigned O.N.C. de Mexico S.A. de C.V., a Mexican corporation (“ONCM”) whose address is ·, unconditionally promises to pay to the order of Minera San Augusto, S.A. de C.V. (the “Holder”) at ·, or at such other place as the Holder of this Note may from time to time designate in writing, without deduction or setoff, in lawful money of Canada, the principal sum of $1,750,000 (the “Principal Amount”), together with interest, if any, on such Principal Amount and any other amounts due under this Note.

1.

Payment.  ONCM shall pay to the Holder $1,750,000 on ·, 2001 [360 days after Closing] (the “Due Date”).  The Principal Amount may be prepaid in whole or in part at any time without premium or penalty.  Unless the Holder shall otherwise elect, each payment made under this Note shall be applied first to costs and expenses incurred in connection with the enforcement of this Note, next to interest accrued under this Note, if any, and any balance shall be applied to reduce the Principal Amount of this Note.

2.

Late or Partial Payments.  The acceptance by the Holder of any payment that is less than the entire amount then due under this Note shall be on account only and shall not constitute a waiver of the obligation of ONCM to pay such entire amount.  The failure of ONCM to pay the entire amount then due under this Note shall be and continue to be an event of default under this Note, notwithstanding the acceptance by the Holder of less than such entire amount on account, and the Holder shall thereafter, until such entire amount is paid (and notwithstanding acceptance by the Holder thereafter of further sums on account or otherwise), be entitled to exercise all rights and remedies provided for in this Note on the occurrence of an event of default under this Note.  The acceptance by the Holder of any amount due under this Note after the same is due shall not constitute a waiver of the right to require prompt payment, when due, of all other amounts due under this Note or to declare that an event of default has occurred under this Note with respect to any other amount not paid when due.

3.

Default.  If any payment required under this Note is not made when due, the entire unpaid Principal Amount of this Note, together with any other amount due under this Note, shall, at the option of the Holder, become due and payable without presentment, demand, protest or notice of any kind, all of which are expressly waived by ONCM and all endorsers, guarantors, sureties, accommodation parties and other persons at any time liable for all or any portion of the indebtedness evidenced by this Note, and shall thereafter earn interest, both before and after judgment, at a nominal rate (the “Default Rate”) of 12 percent per annum with interest upon overdue interest at the same rate.  Any forbearance, failure or delay by the Holder in exercising any right or remedy under this Note or otherwise available to the Holder shall not be deemed to be a waiver of such right or remedy, nor shall any single or partial exercise of any right or remedy preclude the further exercise of such right or remedy.  ONCM shall pay all costs and expenses incurred by the Holder in connection with the enforcement of this Note (regardless of the particular nature of such costs and expenses and whether incurred before or after the initiation of suit or before or after judgment), including, without limitation, court costs and trustee’s and attorneys’ fees and costs.

4.

Security.  This Note is secured by a security agreement and Blanket Guarantee issued pursuant to the terms of an Asset Purchase Agreement dated as of the date hereof between ONCM, the Holder and National Gold Corporation (the “Asset Purchase Agreement”) and the documents, agreements, certificates and instruments contemplated therein creating a lien and/or security interest on certain real and personal property rights and interests of ONCM hereof, all as contemplated in the said Asset Purchase Agreement and ancillary documents, as they may be modified or amended from time to time.

5.

Usury.  Notwithstanding any other provision contained in this Note, in the Asset Purchase Agreement or in any other agreement entered into in connection with this Note, if the Holder ever receives as interest under this Note or the Asset Purchase Agreement an amount which would result in interest being charged at a rate exceeding the maximum allowed by law, such amount or portion as would otherwise be excessive interest shall automatically be applied toward reduction of the unpaid Principal Amount then outstanding under this Note, and not toward the payment of interest.

6.

Assignment.  The Holder may assign or transfer all or any part of the Holder’s rights or obligations under this Note and on request of the Holder ONCM shall issue and deliver new promissory notes having the same terms and conditions as this Note (the “Replacement Notes”) except that the principal amount under the Replacement Notes shall equal in the aggregate the principal amount outstanding under this Note.  ONCM may not assign or transfer, whether absolutely, by way of security or otherwise, all or any part of ONCM’s rights or obligations under this Agreement without the Holder’s prior written consent.

7.

Miscellaneous.  ONCM and all endorsers, guarantors, sureties, accommodation parties and other persons at any time liable for all or any portion of the indebtedness evidenced by this Note consent to all extensions of time, renewals, waivers or modifications that may be granted by the Holder with respect to the payment or other provisions of this Note, the release of all or any portion of any security given in connection with this Note, with or without substitution, and the release of any party liable under this Note.  Time is of the essence with respect to all obligations of ONCM under this Note.  The unenforceability or invalidity of any provisions of this Note shall not affect the enforceability or validity of any other provision of this Note.  The terms of this Note shall bind ONCM and inure to the benefit of the Holder.  This Note shall be governed by British Columbia law.  This Note, the Asset Purchase Agreement and any other written agreement entered into in connection with this Note are the final expression of the agreement between the Holder and ONCM and may not be contradicted by evidence of any alleged oral agreement.

8.

Conflicts.  In the event of a conflict between the provisions of this Note and the provisions of the Asset Purchase Agreement, the Asset Purchase Agreement shall prevail.

Vancouver, British Columbia

Canada V6C 1J9

Re:      Assets Purchase Agreement

Gentlemen:

We have acted as counsel to MINERA SAN AUGUSTO, S.A. DE C.V. a Mexican corporation (the “Seller”), and give this opinion at the request of Seller, in connection with the preparation, execution and delivery of that certain Asset Purchase Agreement, the permits and related documents (the “Purchase Agreement”) dated as of January 1st, 2000 by Seller in favor of O.N.C. de México, S.A. de C.V. (the “Buyer”), and the various documents referred to in each such document and relating thereto.  Terms used herein and not otherwise defined have the meanings given to them in the Purchase Agreement.

We have examined the Purchase Agreement, the documents furnished by the Seller pursuant to the Purchase Agreement, the organizational documents of the Seller and all amendments thereto as certified by the appropriate governmental personnel of Mexico (the “Charter”); and the bylaws of the Seller and all amendments thereto (the “Bylaws”).  In addition, we have examined the originals, or copies certified to our satisfaction, of such other corporate records of the Seller, certificates of public officials, and agreements, instruments, permits, authorizations and other documents.

In rendering this opinion, we have reviewed the due authorization, execution and delivery of each document referred to herein by all parties.

Based upon the foregoing, and subject to the comments and qualifications set forth below, it is our opinion that:

1.

The Seller is a corporation duly organized and validly existing under the laws of Mexico and is duly qualified to transact business and should be considered as in good standing as a foreign corporation in every jurisdiction in which failure to qualify may materially adversely affect (i) the financial condition or operations of the Seller of (ii) the ability of the Seller to perform its obligations under the Purchase Agreement or any related agreement.

2.

The Seller has all requisite corporate power and authority to conduct its business, to own and transfer its property and to execute and deliver, and to perform all of its obligations under the Purchase Agreement and all related agreements.

3.

The execution, delivery and performance by the Seller of the Purchase Agreement and all related agreements and documents are within the Seller’s corporate powers do not contravene, or constitute a default under (i) the Charter or the Bylaws or (ii) any law, rule or regulation applicable to the Seller or (iii) any material agreement, judgment, injunction, order, decree or other material instrument binding upon the Seller.  

4.

Seller agrees in the execution of the Purchase Agreement and all related agreements by a duly authorized officer of the Seller, and it is of our opinion that all such agreements and documents are the legal, valid and binding obligations of the Seller enforceable against the Seller in accordance with their respective terms, except as enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting creditors’ rights generally and by the effect of general principles of equity.

5.

That from the documents we have reviewed and have been provided by the Seller, it is the legal only registered concessionary of the Mineral Rights derived from the assets and mining lots, which are located in the municipality of __________;

6.

That from the documents we have reviewed and have been provided by the Seller, the Assets and mining lots are legal, in force and in good standing mining concessions in accordance with the laws of the Mexican Republic;

7.

The Assets and mining lots either we have reviewed documents or been informed by the Seller that the Assets and the mining lots, were legally acquired, all of them were properly located and denounced, all required locations and validation work was properly performed, recorded and filed with appropriate governmental agencies;

8.

From all the documentation we have reviewed, we understand that the Assets and the mining lots are clear and free on any liens and encumbrances and/or limitation of ownership;

9.

We have not been informed nor have received any communication from where we can understand there is a claim or challenge against to the ownership of the Assets and the mining lots nor, to its knowledge is there any basis therefore and that there are no outstanding agreements or options to acquire or purchase the Mineral Rights over the Assets and the mining lots or any portion thereof which are not previous agreements with ONCM and that no PERSON is entitled to any royalty or other payment as rent or royalty in respect of any Minerals coming form the mining lots; 

10.

We have not been informed nor have received any communication from where we can understand there is no right interest in any of the Assets and the mining lots asserted by others because of overlapping or conflicting any of the Mineral Rights.

All assessment work and tax payments required to hold the Assets and the mining lots and mining concessions thereto has been performed or paid through out their existence to date.

11.

The Seller has acquired and currently hold all Permits and Licenses, and other concessions granted by or entered into with, or applicable to the Assets and the mining lots or that are material to the Sellers Assets and mining lots and to the Sellers mining operation, in all material respects.

12.

As far as we understand from what we have reviewed or being informed from the Seller, the Assets were legally acquired and those imported have paid all duties and were legally imported, and have as well, paid applicable taxes through out their life.

14.

From what we have reviewed or being informed by The Seller the Mulatos Project has been conducted with all permits, licenses, approvals, authorizations, consents, registrations or other actions required under Mexican Law, including but not limited to the environmental Law which have been obtained in compliance with Law.

All written arrangement supersede or oral arrangements agreed with them and those written arrangement are bound between the parties and among third parties.

18.

The Seller is subject to civil, commercial and mining law with respect to its obligations under the Purchase Agreement and all related agreements.  The execution, delivery and performance of all such agreements constitute commercial acts as opposed to governmental acts.  The Seller and its property do not enjoy, in the courts or under the laws of Mexico, any right of immunity from suit, setoff or attachment or execution on a judgment in respect of the obligations of the Seller under the Purchase Agreement and related agreements.

We are qualified to practice law in Mexico and do not purport to be expert on, or to express any opinion concerning, any laws other than the law of Mexico.
