William J. Crowl, Chief Mining Geologist

Mr. Crowl is a Mining Geologist with over 38 years of experience spanning the entire spectrum of mining geology from hands-on operations to managing geology and mining engineering organizations, to providing technical audits, feasibility studies and property acquisition evaluations.  Since 1996, his experience has expanded in the areas of technical due diligence and auditing for project financing and Stock Exchange reporting requirements for resources and reserves.  He has managed a number of due diligence audits and reviews for project financing and has been directly responsible for the resource and reserve portions of most of those studies.  He is an accomplished Project Manager and is a Qualified Person as defined by Canadian National Instrument 43-101.

Of particular note is his involvement with the successful Aynak Copper Tender in Afghanistan, where he was the Project Manager and directly participated in the entire tender process – from bid solicitation to contract negotiations.  Precious metals exploration, resource modeling and estimation and mine operations have been central to his work, ranging in location from the USA, to Central and South America, Africa, China,  and Russia.  Copper experience includes work on the El Tesoro, Michilla, Longacho Este, Zaldivar and Candelaria in Chile, Lyon in Nevada, Leslie Den (Mazama) in Washington, Udokan in Siberia and Aynak in Afghanistan.  Deposit types investigated include VMS, sediment-hosted and porphyry/disseminated base metal deposits, layered mafic intrusives, carbonatites, epithermal precious metal deposits, sand and gravel, coal, as well as sedimentary and hard rock uranium deposits.
