3. Near-Term Catalysts – Joint Ventures (Partner Funded)

Battery Mineral Resources Limited ("BMR") – Cobalt project near Matachewan, Ontario "Island 27 Prospect"

A ground follow-up prospecting, mapping and sampling program was completed in 2017. Selective historical geophysical data has been reviewed and reprocessed. Historical drill holes were reviewed, re-logged and re-sampled.  A detailed exploration effort for 2018 is planned, including diamond drilling of the target.  

On June 1, 2017, the Golden Valley entered into mining option agreement with BMR pursuant to which the Company will grant to BMR an option to acquire up to an 80% interest in the Island 27 Property, in consideration for which the Company will receive $500,000 in cash payments and Battery Minerals will incur $5,000,000 in expenditures over a 4-year period. Once the option is exercised, Golden Valley will have a 20% free carried interest in the property and a 1% NSR.

Alexandria Minerals Corporation ("Alexandria") – Gold Project near Val-D'Or: "Centremaque Gold Prospect"

Alexandria recently reported that a total of 7 drill holes for 3,348 metres were completed at Centremaque, of which two were included in Alexandria's press release dated April 9, 2018 (CAX-18-001 and CAX-18-003) to test the two known zones of mineralization. The information that follows has been prepared by partner and program operator Alexandria and has not been independently verified by Golden Valley:  Alexandria reported that the shallow zone is hosted in brecciated, biotite and chlorite altered ultramafic volcanics with up to 5% pyrrhotite and 1% chalcopyrite from 285.85 m to 286.50 m and returned up to 0.65 m @ 14.50g/t Au in hole CAX-18-001.  The deeper zone contained a zone of chlorite-tourmaline altered sediments/volcanics located north of the ultramafics, containing up to 9 visible gold grains gold grains between 337.10 m and 338.75 m. The zone returned up to 1.80 m @ 36.62 g/t Au, including 1.00 m @ 40.57 g/t Au at a depth of 337.10 m also in hole CAX-18-001. Hole CAX-18-003 intersected both zones with lower order intercepts. Drilling to date has shown the zone to extend for 300m. Please see Alexandria's press release dated April 9, 2018 for further information.

Alexandria may earn an 80% interest in the Centremaque gold project by issuing treasury shares of Alexandria to Golden Valley over a four year period from date of signing with a total value of $250,000, and by conducting exploration activities totaling $4 million over the same four year period, of which $250,000 is to be spent in the first year of the option agreement. The price of the shares, and therefore the number of shares to be issued, is determined by reference to the market price at the time each tranche is due.

Bonterra Resources Inc. ("Bonterra") – Gold Project near Osisko/Windfall Lake: "Lac Barry Prospect"

The Lac Barry Prospect is located to the southwest along the projected strike extension of mineralization on the West Arena Property of Bonterra's 100% owned Gladiator Gold Project, which is currently being drilled on by Bonterra. In addition, the Lac Barry Prospect is adjacent to and immediately southwest of Bonterra's Coliseum Property.

Bonterra is planning a follow-up exploration program per results obtained from 2017. Further ground geophysical and geochemical programs plus mapping, prospecting is also planned. The proposed drilling program will be success based and focus on mineralized trends extending west from Gladiator deposit.

In 2016, Golden Valley granted an option to Bonterra to acquire an 85% interest in the Lac Barry Prospect. In accordance with the option agreement, Bonterra issued to Golden Valley Mines 519,480 common shares in the capital of Bonterra having an aggregate value of $200,000, and Bonterra must incur expenditures in an aggregate amount of $2,000,000 over a three year period on the Lac Barry Prospect.

Bonterra has met the option agreement expenditure requirements for the second anniversary date (March 10, 2018) of $750,000.

Upon the exercise of the option, Golden Valley shall retain a 15% free carried interest in the Lac Barry Prospect and a 3% net smelter royalty ("NSR"), with 1% of the NSR being subject to a buyback in favour of Bonterra for $1 million payable by Bonterra to Golden Valley.
