Exploration History

1925: a group of nine claims was staked by Ray Howey for McIntyre Porcupine Mines Ltd. 1937: 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. 1956: Wright-Hargreaves Mines Ltd. of the Little Long Lac Gold Mines organization obtained control of the property. Prior to 1937: Considerable surface work and several diamond drill holes were completed. No. 1 shaft was begun in 1938, and reached a depth of 163.2 m by the end of the year. No. 2 shaft was also started in 1938, and reached a depth of 327.9 m. No. 3 shaft was sunk as a winze from the No. 1 shaft, and reached a depth of 747.3 m. Later it was driven to surface. A total of 14,016 m of drifting, crosscutting and raising was completed underground. 1952: in a search of additional ore, 3996 m of drilling was completed from underground. Lac Minerals (now Barrick Gold) obtained the Hasaga property in 1956. 1959-1986: the property was inactive. 1987-1988: Lac Minerals conducted drilling programs 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. 1996: Barrick conducted a drill program of 4 holes for a total of 2897.7 m in support of a closure plan headed by Golders & Assoc. 2014: Premier Gold purchased the property from Goldcorp. 2015: Premier Gold completed 130 drill holes totalling 60,310 m.

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 main zones of quartz stringers are restricted to well defined fracture zones that are found in particular parts of the porphyry. A roll is found at the 260 m level and in this roll, the zone narrows and fractures are poorly developed. The A block of ore was approximately 300 m long and extended down to the 442 m level. The B block was approximately 210 m long and extended from the 488 m level to the 717 m level. GEOPHYSICAL DATA: A 600 gamma airborne magnetic high occurs to the south of the mine and probably represents the Howey diorite.

Mineralization Comments

Jul 20, 2016 (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 Over 1.5 million tons grading 0.14 oz/ton (4.800 g/tonne)Au have been recovered. Estimated reserves are: C Block - 200,203 tons @ 0.192/ton Au. (From diamond drilling). Stopes (IN PLACE) - 41,430 tons @ 0.104 oz/ton (3.566 g/tonne) Au. Pillars - 6,365 tons @ 0.134 oz/ton (4.594 g/tonne) Au. TOTAL - 247,998 tons @ 0.176 oz/ton (6.034 g/tonne) Au. 1996: no new results, testing targeted the C zone 2015: Premier intersected wide gold zones. Thenew Central zone consists of a series of conjugate structures within the Dome Granodiorite.

Dec 17, 2020 (Therese Pettigrew) - Drilling by Premier in 2015 has confirmed the Hasaga Porphyry target with multiple intercepts of mineralization surrounded by broad haloes of lower grade mineralization (typically less than 0.60 g/t Au) which would result in some intercepts exceeding 100 metres in core length. The predominant ore host is the strongly altered Hasaga Porphyry unit and also includes portions of the sheared volcanic wallrocks. Ore bodies and mineralized horizons identified within the Porphyry unit are sub-vertical. Mineralization in the Hasaga Zone is characterized by intervals of strongly silicified and sericite alteration indicative of complex hydrothermal fluid history. Alteration appears two-staged, with an early porphyry related phase with wide swaths of silica and sericite alteration. A later, more localized carbonate alteration event appears to be accompanied by a high density of quartz tourmaline veins with fine to coarse pyrite, lesser chalcopyrite and occasional visible gold. This second alteration phase is preserved in late mafic dyke which cross-cut sericite and silica alteration zones. Mineralized horizons are best developed in the SW portion of the Hasaga Porphyry (Sections E1400-E900) and the along strike continuation remains open for further expansion to the SW. Highlights from the Hasaga zone include 0.98 g/t Au over 126.0m (including 2.04 g/t Au over 49.0 m) from HMP021, 1.11 g/t Au over 87.0 m from HMP037, 1.68 g/t Au over 49.0 m (including 2.41 g/t Au over 17.6 m) in HMP039, 0.96 g/t Au over 36.0 m and 1.72 g/t Au over 37.0 m in HMP074 and 1.50 g/t Au over 18.0 m and 0.87 g/t Au over 34.0 m in HMP076 (Assessment report 20000014412).

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.
