Dear Sirs:

Re:     Option to Aberdene Mines Ltd. to Earn a 75% Undivided Interest in the Interest of Consolidated Global Minerals Ltd. in the Slide Mine and Horsefal Projects

---

Global Minerals Ltd. ("Global") is currently the registered and beneficial owner of a 50% undivided interest in the mineral claims comprised in the Slide Mine and Horsefal Projects located in Boulder County, Colorado as more particularly described in Schedule "A" hereto (collectively, the "Properties"), free and clear of all liens, charges and encumbrances.

Aberdene Mines Ltd. ("Aberdene") wishes to conduct due diligence investigations in respect of the Properties for the purpose of determining whether to enter into a formal option agreement (the "Option Agreement") with Global pursuant to which Global would grant to Aberdene the option to earn a 75% undivided interest in Global's interest in the Properties (the "Option").  Pending completion of due diligence and fulfillment of other conditions set out below, the parties have agreed to enter into this Letter of Intent in connection with the proposed Option.

1. Exclusivity:  The parties agree that for a period of 120 days commencing on the date of this Letter of Intent (the "Exclusive Period"), Aberdene will have the exclusive right to:
2. conduct due diligence investigations in respect of the Properties and Global's interest therein;
3. negotiate the terms and conditions of the Option;
4. Conversion of Interest.  Global agrees to use its best commercial efforts to negotiate and complete, prior to the expiry of the Exclusive Period, the transfer of the other 50% undivided interest in the Properties from the current owner(s) of the Properties to Global and the conversion of such interest by the current owner(s) into a royalty equal to 5% of net smelter returns (the "Royalty") with provision for the purchase of percentage points to reduce the Royalty.
5. Option Agreement.  On completion of satisfactory due diligence by Aberdene, the parties agree to negotiate in good faith and execute the Option Agreement, which will contain the terms and conditions set out in section 4 hereof and other terms and conditions substantially similar to those contained in the option agreements entered into by the parties in respect of the Quarter Circle S and Cornucopia Properties, to be executed by the parties within 30 days of completion of due diligence by Aberdene.
