The Paterson Lake Property is located 75 km north of Kenora, northwestern Ontario in Paterson Lake and Treelined Lake Areas and can be accessed by English River Road and several logging and drill roads which dissect the property. The Property is composed of 64 mining claims totaling 1198 ha and is approximately 15 km by 5 km in size. The Property hosts multiple commodities: petalite (Li), spodumene (Li), Ta-oxides and feldspar (Rb, Cs).
The Paterson Lake Property is located within the Separation Lake Greenstone Belt which hosts the Separation Rapids Pegmatite Field. The Separation Rapids Pegmatite Field is considered to be the easterly extension of the Winnipeg River – Cat Lake Pegmatite Field which hosts the Tanco pegmatite mine. The Separation Rapids Pegmatite Field is known to contain numerous petalite pegmatites including the Big Whopper, Big Mack and Marko’s pegmatites. Avalon Advanced Materials Inc.’s (“Avalon”) Separation Rapids Lithium Project includes the Big
Whopper petalite pegmatite and is located approximately 1 km west of Power Metals’ Separation Lake Property within the same greenstone belt. Avalon completed a NI 43-101 Technical Report PEA (dated Nov. 10, 2016) on their Separation Rapids Lithium Project. As at Oct. 21, 2016, Avalon’s mineral resource estimate for the Separation Rapids Lithium Project is Measured plus Indicated of 8.00 Mt at 1.29 % Li2O, 39 % total feldspar, 0.006 % Ta2O5, 0.021 %Cs2O and
0.352 % Rb2O and Inferred of 1.63 Mt at 1.42 % Li2O, 39 % total feldspar, 0.008 % Ta2O5,
0.016 %Cs2O and 0.360 % Rb2O. Champion Bear Resources Ltd’s petalite, Ta-oxide and pollucite-bearing Marko’s pegmatite is located near the claim boundary immediately adjacent and to the east of Power Metal’s Property. Marko’s pegmatite likely extends onto Power Metals property.
In 1993-1994, Fred Breaks of the Ontario Geological Survey conducted mapping programs on the Separation Rapids Pegmatite Field (Summary of Field Work and Other Activities 1993 and
1994, Misc. Pap. 162 and 163) and identified multiple petalite pegmatites within the Pegmatite
Field (Figure 1 and 2).
In 1996-2003, Tantalum Mining Corporation (“Tanco”) conducted mapping, lithogeochemical sampling, enzyme leach soil sampling, and drilling with a total of 20 drill holes on Power Metal’s Paterson Lake Property. Highlights of Tanco’s exploration program include:
Tanco’s exploration program resulted in the identification of petalite pegmatite dykes both on surface and at depth and the identification of lithogeochemistry and enzyme leach soil anomalies which can be used to explore for additional buried pegmatites. No exploration has been completed on the Property since 2003. Separation Lake Property has multiple exploration targets with the potential to find a lot more petalite pegmatite dykes.
