Exhibit 4.2


 


GENTOR RESOURCES INC.


 


Stock Option Plan


 


The board of directors
of Gentor Resources Inc. (the "Corporation") wishes to establish a stock option plan (the "Plan") governing
the issuance of stock options (the "Stock Options") to directors, officers and employees of the Corporation or subsidiaries
of the Corporation and persons or corporations who provide services to the Corporation or its subsidiaries on an on-going basis,
or have provided or are expected to provide a service or services of considerable value to the Corporation or its subsidiaries.
Capitalized terms, not otherwise defined herein, have the meanings ascribed thereto in the TSX Venture Exchange Corporate Finance
Manual.


 


The terms and conditions
of the Plan for issuance of Stock Options are as follows:


 


		1.	Purposes



 


The principal purposes
of the Plan are:


 


		(a)	to retain and attract qualified directors, officers, employees and service providers which the
Corporation and its subsidiaries require;



 


		(b)	to promote a proprietary interest in the Corporation and its subsidiaries;



 


		(c)	to provide an incentive element in compensation; and



 


		(d)	to promote the profitability of the Corporation and its subsidiaries.



 


		2.	Reservation of Shares



 


Subject to Section
10 of the Plan, the number of common shares in the capital of the Corporation (the "Common Shares") reserved from time
to time for issuance to Eligible Optionees (as hereinafter defined) pursuant to Stock Options under the Plan shall not exceed 11,000,000
Common Shares.


 


		3.	Eligibility



 


Stock Options shall
be granted only to persons, firms or corporations ("Eligible Optionees") who are Directors, Employees, Consultants or
Management Company Employees of the Corporation or a subsidiary of the Corporation. Where the Eligible Optionee is an Employee,
Consultant or Management Company Employee, the board of directors of the Corporation (the "Board") shall confirm that
the Eligible Optionee is a bona fide Employee, Consultant or Management Company Employee, as the case may be, of the Corporation
or a subsidiary of the Corporation prior to any grant of Stock Options.


 


Stock Options may also
be granted to a corporation which is wholly-owned by an Eligible Optionee if the corporation agrees not to effect or permit any
transfer of ownership or option of shares of the corporation, nor to issue further shares of any class in the corporation to any
other individual or entity as long as any Stock Options granted to the corporation remain outstanding, without the prior written
consent of the TSX Venture Exchange. Unless the context otherwise requires, the term Eligible Optionee as used herein, shall include
any such corporation.


 



    	 



    	 



    

 


		4.	Granting of Stock Options



 


The Board may from
time to time grant Stock Options to Eligible Optionees. At the time a Stock Option is granted, the Board shall determine the number
of Common Shares of the Corporation available for purchase under the Stock Option, the date when the Stock Option is to become
effective and, subject to the other provisions of this Plan, all other terms and conditions of the Stock Option. An Eligible Optionee
may hold more than one Stock Option at any time, however, at no time shall:


 


		(a)	the number of Common Shares reserved for issuance pursuant to Stock Options granted to Insiders
exceed 10% of the outstanding Common Shares;



 


		(b)	the number of Stock Options granted to Insiders, within a 12 month period, exceed 10% of the outstanding
Common Shares;



 


		(c)	the number of Common Shares reserved for issuance pursuant to Stock Options or pursuant to any
other stock purchase or option plans of the Corporation granted to any one Eligible Optionee exceed 5% of the outstanding Common
Shares;



 


		(d)	the number of Common Shares issued pursuant to Stock Options to any one Eligible Optionee, within
a one-year period, exceed 5% of the outstanding Common Shares;



 


		(e)	the number of Stock Options granted to any one Consultant in a 12 month period exceed 2% of the
outstanding Common Shares; or



 


		(f)	the aggregate number of Stock Options granted to persons employed in Investor Relations Activities
exceed 2% of the outstanding Common Shares in any 12 month period without the express consent of the TSX Venture Exchange.



 


Any Stock Options granted
to a corporation referred to in Section 3 hereof shall be included in the calculation of the Stock Options held by an Eligible
Optionee.


 


		5.	Exercise Price



 


The exercise price
(the "Exercise Price") of each Stock Option shall be determined in the discretion of the Board at the time of the granting
of the Stock Option, provided that the exercise price shall not be lower than the "Market Price". "Market Price"
shall mean the last closing price of the Common Shares on the TSX Venture Exchange prior to the date the Stock Option is granted;
provided that in the event the Common Shares are not listed on the TSX Venture Exchange but are listed on another stock exchange
or stock exchanges, the foregoing reference to the TSX Venture Exchange shall be deemed to be a reference to such other stock exchange,
or if more than one, to such one as shall be designated by the Board, and to the extent that the Common Shares are not listed on
any exchange, the Market Price shall be such price as is determined by the Board in good faith.


 


		6.	Term and Exercise Periods



 


		(a)	All Stock Options shall be for a term determined in the discretion of the Board at the time of
the granting of the Stock Options, provided that no Stock Option shall have a term exceeding five years and, unless the Board at
any time makes a specific determination otherwise, a Stock Option and all rights to purchase Common Shares pursuant thereto shall
expire and terminate immediately upon the Eligible Optionee who holds such Stock Option ceasing to be at least one of a Director,
Employee, Management Company Employee or Consultant of the Corporation or a subsidiary of the Corporation.



 




    	2



    	 



    




 


		(b)	Unless otherwise determined by the Board at the time of the granting of the Stock Options pursuant
to clause 6(c)(iii) below, 1/4 of the Stock Options granted pursuant hereto will vest on each of the 6 month, 12 month, 18 month
and 24 month anniversaries of the date of the grant of the Stock Options (the "Grant Date"). For greater clarity, unless
otherwise determined pursuant to the terms hereof, all Stock Options granted to an Eligible Optionee will be available to exercise
and purchase Common Shares on the 24 month anniversary of the Grant Date.



 


		(c)	By way of example, without limiting the generality of the foregoing or the discretion of the Board,
the Board may, at the time of the granting of the Stock Option, determine:



 


		(i)	that a Stock Option is exercisable only while the Eligible Optionee remains at least one of a Director,
Employee, Management Company Employee or Consultant and for a limited period of time ("Additional Period") after the
Eligible Optionee ceases to be at least one of a Director, Employee, Management Company Employee or Consultant (which Additional
Period may not exceed 90 days or, in the case of an Eligible Optionee engaged in Investor Relations Activities, 30 days);



 


		(ii)	that a Stock Option can be exercisable for an Additional Period or for its remaining term (which
Additional Period or remaining term may not exceed one year) after the death, disability or incapacity of an Eligible Optionee;



 


		(iii)	that a Stock Option has a different vesting schedule than that specified in subsection 6(b) above;
or



 


		(iv)	that a Stock Option may provide for early exercise and/or termination or other adjustment in the
event of a death of a person and in other circumstances, such as if the Corporation shall resolve to sell all or substantially
all of its assets, to liquidate or dissolve, or to merge, amalgamate, consolidate or be absorbed with or into any other corporation.



 


		7.	Non-Assignability



 


Other than a limited
right of assignment, subject to the terms upon which the Stock Option is granted, in the event of the death of an Eligible Optionee
to allow the exercise of Stock Options by the Eligible Optionee's legal representative, Stock Options shall not be assignable or
transferable by the Eligible Optionees.


 


		8.	Payment of Exercise Price



 


All shares issued pursuant
to the exercise of a Stock Option shall be paid for in full at the time of exercise of the Stock Option and prior to the issue
of the shares. All Common Shares issued in accordance with the foregoing shall be issued as fully paid and non-assessable Common
Shares.


 


		9.	Non-Exercise



 


If any Stock Option
granted pursuant to the Plan is not exercised for any reason whatsoever, upon the expiry of the Stock Options pursuant to the terms
of its grant or the terms hereof, the shares reserved and authorized for issuance pursuant to such Stock Option shall revert to
the Plan and shall be available for other Stock Options. Notwithstanding the foregoing, at no time shall there be outstanding Stock
Options exceeding, in the aggregate, the number of Common Shares reserved for issuance pursuant to Stock Options under this Plan.


 



    	3



    	 



    

 


		10.	Adjustment in Certain Circumstances



 


In the event:


 


		(a)	of any change in the Common Shares through subdivision, consolidation, reclassification, amalgamation,
merger or otherwise; or



 


		(b)	of any stock dividend to holders of Common Shares (other than such stock dividends issued at the
option of shareholders of the Corporation in lieu of substantially equivalent cash dividends); or



 


		(c)	that any rights are granted to holders of Common Shares to purchase Common Shares at prices substantially
below fair market value; or



 


		(d)	that as a result of any recapitalization, merger, consolidation or otherwise the Common Shares
are converted into or exchangeable for any other shares;



 


then in any such case the Board may make
such adjustment in the Plan and in the Stock Options granted under the Plan as the Board may in its sole discretion deem appropriate
to prevent substantial dilution or enlargement of the rights granted to, or available for, holders of Stock Options, and such adjustments
may be included in the Stock Options.


 


		11.	Expenses



 


All expenses in connection
with the Plan shall be borne by the Corporation.


 


		12.	Compliance with Laws



 


The Corporation shall
not be obliged to issue any shares upon exercise of Stock Options if the issue would violate any law or regulation or any rule
of any governmental authority or stock exchange. The Corporation shall not be required to issue, register or qualify for resale
any shares issuable upon exercise of Stock Options pursuant to the provisions of a prospectus or similar document, provided that
the Corporation shall notify the TSX Venture Exchange or any other stock exchange on which the shares of the Corporation are listed
and any other appropriate regulatory bodies of the existence of the Plan and the issuance and exercise of Stock Options.


 


In addition to any
resale restrictions that may be applicable under applicable securities laws, all Stock Options and any shares issued on the exercise
of Stock Options shall be legended with a four month hold period from the date the Stock Options are granted.


 


		13.	Disinterested Shareholder Approval



 


Disinterested shareholder
approval shall be obtained by the Corporation prior to any reduction in the Exercise Price if the Optionee is an Insider of the
Corporation at the time of a proposed reduction of the Exercise Price.


 



    	4



    	 



    

 


		14.	Form of Stock Option Agreement



 


All Stock Options shall
be issued by the Corporation in a form which meets the general requirements and conditions set forth in this Plan and the requirements
of the TSX Venture Exchange or such other exchange on which the shares of the Corporation are listed from time to time.


 


		15.	General Offer for Common Shares



 


If a bona fide offer
(the "Offer") for the Common Shares is made to shareholders
generally, which Offer, if accepted in whole or in part, would result in the offeror exercising control over the Corporation within
the meaning of subsection 1(3) of the Securities Act (Ontario), then the Corporation shall, immediately upon receipt of
notice of the Offer, notify each Eligible Optionee then holding Stock Options of the Offer, with full particulars thereof, whereupon,
notwithstanding clause 6(b) hereof but subject to any necessary regulatory approval, such Stock Options may be exercised in whole
or in part by the Eligible Optionee so as to permit the Eligible Optionee to tender the Common Shares received upon such exercise
(the "Optioned Shares") pursuant to the Offer. If:


 


		(a)	the Offer is not completed within the time specified therein; or



 


		(b)	the Eligible Optionee does not tender the Optioned Shares pursuant to the Offer; or



 


		(c)	all of the Optioned Shares tendered by the Eligible Optionee pursuant to the Offer are not taken
up and paid for by the offeror in respect thereof,



 


then the Optioned Shares or, in the case
of clause (c) above, the Optioned Shares that are not taken up and paid for, shall be returned by the Eligible Optionee to the
Corporation and reinstated as authorized but unissued Common Shares and the terms of the Stock Options as set forth in clause 6(b)
hereof shall again apply to the Stock Options. If any Optioned Shares are returned to the Corporation under this Section 15, the
Corporation shall refund the Exercise Price to the Eligible Optionee for such Optioned Shares. In no event shall the Eligible Optionee
be entitled to sell the Optioned Shares otherwise than pursuant to the Offer.


 


		16.	Amendments and Termination 



 


The Corporation shall
retain the right to (a) amend from time to time the terms of the Plan or to terminate the Plan by resolution of the Board, and
(b) amend from time to time the terms of outstanding Stock Options by resolution of the Board. Any such amendments or termination
shall be subject to the consent of any applicable regulatory body, including any stock exchange on which the Corporation's shares
are listed (to the extent such consent is required). Any amendment to the terms of outstanding Stock Options shall be subject to
the consent of the Eligible Optionee holding such Stock Options. Any amendment to the terms of the Plan shall take effect only
with respect to Stock Options granted thereafter, provided that such amendment may apply to any Stock Options previously granted
with the consent of the Eligible Optionees holding such Stock Options.


 


		17.	Delegation of Administration of the Plan



 


Subject to the legislation
governing the Corporation, the Board may delegate to one or more directors of the Corporation, on such terms as it considers appropriate,
all or any part of the powers, duties and functions relating to the granting of Stock Options and the administration of the Plan.


 



    	5



    	 



    

 


		18.	Applicable Law



 


This Plan shall be
governed by and construed in accordance with the laws in force in the Province of Ontario, Canada.


 


		19.	Stock Exchange



 


To the extent applicable,
the issuance of any shares of the Corporation pursuant to Stock Options issued pursuant to this Plan is subject to approval of
the Plan by the TSX Venture Exchange or other stock exchange upon which the Common Shares are listed, and the Plan shall be subject
to the ongoing requirements of such exchange.


 


		20.	Administration



 


This Plan shall be
administered by the Board. The Board shall have full and final discretion to interpret the provisions of this Plan and to prescribe,
amend, rescind and waive rules and regulations to govern the administration and operation of this Plan. All decisions and interpretations
made by the Board shall be binding and conclusive upon the Corporation and on all persons eligible to participate in this Plan,
subject to shareholder approval if required by any stock exchange on which the Corporation's shares are listed.
