Exploration History

1895-1899: Empress Gold Mining Company conducted exploration, mine development and production. 1936-37: Empress Consolidated Gold Mines Ltd. carried out outcrop stripping, diamond drilling, bedrock sampling (surface and underground), assays. 1974: MacGregor, R.A. conducted ground magnetic and electromagnetic surveys. 1982-87: Micham Exploration Inc. conducted airborne and ground magnetic and electromagnetic surveys, ground induced polarization (IP) survey, geological and geochemical surveys, trenching, sampling, assays, diamond drilling (22 diamond drill holes (ddh) for 3231 m). 1997: Landis Mining Corporation and McArthur Minerals Inc. carried ou ground magnetic and electromagnetic surveys, humus geochemistry, geological mapping, bedrock sampling and assays. 1999-2005: Cameco Gold Inc. conducted ground IP survey, geological surveys, till sampling, outcrop stripping, bedrock sampling, assays, re-sampling historic Micham drill core (12 holes). 2006-14: Alto Ventures Limited carried out geological surveys, bedrock sampling, soil sampling, assays, diamond drilling (2 ddh for 332 m).

Lithology

Lithology Comments

Sep 12, 2019 (Andrew Tims) - Outcrop Area 1E (stripped by Cameco Gold Inc. in 1999) exposes an approximately 7 to 10 m wide portion of the Empress Structure Deformation Zone. The zone consists of intensely deformed quartz-sericite schist hosting quartz-carbonate veins. The following description of the Empress structure was provided by Koziol (2007): The Empress structure is a zone of shearing and deformation that has been previously exposed by trenching and stripping at various locations (Samson, 1999). The stripped area extends for approximately 1.6 km from the eastern property boundary of the former Empress Mine (Cameco’s L0E) and extending eastward to L15+00E. The most sheared portion of the structure varies from less than 15 to 25 m in width, and strikes slightly oblique to stratigraphy, at roughly 070° azimuth, dipping variably to the south at 90° to less than 50° but it is confined to an area between mafic flows. The sheared rocks within the structure include quartz-sericite schist and chemical sediment[ary rock]s bordered in the north by a ±graphitic quartz-sericite schist which can be followed eastward past L15+00E and moderately deformed clastic metasediment[ary rock]s found discontinuously along the southern edge of the quartz-sericite schist. A 15 to 25 cm wide lamprophyre dyke occupies the centre of the shear on L1+00E. Structural work by Alto in Trench 1+00E (Cameco Grid Area 1E) indicates that there are only a few fold closures that are defined sufficiently for determining reliable plunge directions. In Trench 1+00E lineation rods along the shear dip plane varied from 105° to 115°in azimuth and dipping 43°. The strike of the shear zone varies from 70° to 95°. The laminated quartz-sericite schist horizon that occupies the Empress structure has been interpreted to be a metasedimentary rock unit (Samson 1999). At this location, the quartz-sericite schist is bounded to the north by a grey to black argillaceous schist and to the south by massive mafic metavolcanic rocks.

Mineralization

Mineralization Comments

Jul 14, 2016 (Andrew Tims) - The rocks of the Empress structure exposed in this trench typically contain <1 to 2% (locally up to 15%) disseminated pyrite, with traces of chalcopyrite (Samson 1999). Channel sampling by Cameco returned only modest gold values from this trench (best assay of 2.24 g/t Au over 0.45 m). However, Cameco did report grab sample results of up to 66.93 g/t Au.

Sep 12, 2019 (Therese Pettigrew) - Samples collected by Alto Ventures from the trench returned assays of up to 2.278 g/t Au (Assessment report 20000003772). DDH 441-84-8 returned an assay of 44.23 g/t Au over 0.61 m (Assessment report 42D15SW0117).
