Point Location Description: N/A

Location Method: Data Compilation

Access Description: The Property partly covers the community of Red Lake and is easily accessed, year round via provincial Highway 105 and Highway 618, which transects the southern part of the Property. Various secondary dirt roads and trails provide access to the remainder of the property.

Exploration History

1925: A group of nine claims was staked by Ray Howey for McIntyre Porcupine Mines Ltd. 1937-1953: J. E. Hammel purchased the claim group. Hasaga Mines Ltd. was incorporated in 1938 to acquire this property and the property of Red Lake Gold Shore Mines Ltd. A total of 218,213 ounces of was gold produced from the combined Hasaga Mine projects. 1953: The 549 m level was driven 823.5 m west from the shaft with 20 DDHs totalling 3996 m drilled. Due to the cost of further development, it was decided to suspend operations before 'C' block was mined. 1956: Wright-Hargreaves Mines Ltd. of the Little Long Lac Gold Mines (LAC Minerals) obtained control of the property. 1977: An induced polarization and resistivity survey conducted by McPhar Geophysics on behalf of Cochenour-Willans Gold Mines Ltd. 1987-1988: Lac Minerals conducted a property-wide exploration program that included detailed geologic outcrop mapping, ground geophysical surveys and a nine hole diamond-drill program totalling approximately 5000 m that were successful in delineating gold mineralization in the down plunge of the C zone and opened up potential for low grade open pit zones in granodiorite. 1995: Barrick Gold took over LAC Minerals. 1996: Barrick compiled historic mining data and conducted a drill program of 4 geotechnical holes for a total of 2897.7 m under supervision by Golders & Associates. 2013-2014: Goldcorp Inc. conducted a property-wide geochemical study that comprised 70 lithological samples, collected at roughly 200 m centres. 2015: Premier Gold Mines acquired a 100% interest in the Hasaga Property from Goldcorp Inc. drilling 130 holes, totalling 60,310 m. 2016: Two sets of composite samples were run for metallurgical testwork at SGS Lakefield, Ontario laboratory.

Geology Comments

Dec 07, 2005 (K R Kettles) - Geological Description: The geological structure is practically identical to that at the Howey Mine. The quartz porphyry dike, which contained the ore bodies on the Howey property extends to the southwest across the central part of this property. The dike was intruded into an elongated tongue of coarse clastic sedimentary rocks which extends into the Howey diorite. Part of the tongue is cut off along the northwest side by the Dome granitic stock. A pink granitic stock, believed to be of the same age as the Dome Stock, cuts across the quartz porphyry dike near the No. 1 shaft. Mafic dikes are present along the margins of the quartz porphyry dike. Structures on the Hasaga property are similar to those on the Howey property. Before the introduction of the porphyry dike, the country rocks were fractured along N 65 deg. E and S60 deg. E directions. The porphyry dike was intruded along the N65 deg. E direction. After the porphyry was emplaced, deformation produced a second set of fractures along directions N20 deg. E and N80 deg. E. The later fractures are well developed in the quartz-porphyry. Later mineralization fluids deposited auriferous quartz veins in the N80 deg. E set of fractures in the quartz porphyry dike. Ore grade mineralization is also found along N 20 deg. E striking faults. DEPOSIT DESCRIPTION: The 'C' block has a strike length of approximately 300 m, and has been investigated from the 595 m level to the 798 m level. The block has not been fully delineated. The mineralization is similar to the rest of the mine. GEOPHYSICAL DATA: A 600 gamma airborne magnetic high occurs to the south of the mine and probably represents the Howey diorite.

Mineralization Comments

Mar 16, 2012 (K R Kettles) - MDI1 DATA: PRODUCTION 1938-52 A AND B BLOCKS: 219,320 OZ AU FROM 1,515,282 TONS MILLED @ AVE. 0.14 OPT AU, ESTIMATED RESERVES 1959 MAINLY C BLOCK: 247,998 TONS @ 0.176 OPT AU Estimated reserves are: C Block - 200,203 tons @ 0.192/ton Au. (From diamond drilling). 1996: drill program tested the down plunge extension of the C zone at a vertical depth of 900m. Intersected low grade gold mineralization at the south contact. 2.5 g/t Au over 17.4 m, 0.95 g/t Au over 15 m.

Alteration Comments

Dec 07, 2005 (K R Kettles) - The normal grey quartz porphyry has been altered to a buff, waxy colour due to the development of sericite. Alteration is most intense along the contacts of the quartz veins. Silicification is common along the margins of many of the veins. The basic dikes show a little carbonatization where cut by the quartz veins.
