1895-1900: The Empress Gold Mining Company was incorporated and various test shafts, adits and pits were sunk on a series of gold-bearing quartz veins. 1936-1937: The Empress Consolidated Gold Mines Ltd. was incorporated and signed an option agreement with Czarina Gold Mines in order to extensively re-evaluate the Empress mine. Dozens of trenches now found on the Empress claims are attributed to this period of activity. 1984-1987: Micham Exploration Inc conducted a diamond drilling program in 1984 consisting of 1557 m (5106 ft) in 12 holes, testing various anomalies detected in the vicinity of the Ursa Major occurrence (486 m in 4 holes), the Empress Mine (587 m in holes), and along the Empress Structure (483 m in 4 holes). 1996: G.R. Daniels, J. Ferguson, and A. Ferguson carried out prospecting, stripping, and trenching. 1998-2005: Cameco Gold Inc. (a subsidiary of Cameco Corporation (Cameco) acquired the property in 1998 and started work in 1999. Cameco’s 1999 program line cutting, IP surveys, and geological mapping. Twelve diamond drill holes totaling 1800 metres drilled previously by Micham Resource in 1984 and 1987 were re-logged and re-sampled by Cameco. In 2000, Cameco performed a geological survey and bulk till sampling program to follow-up previous year’s results. Alto Ventures Limited purchased the property from Cameco Corporation in 2005. 2006: Alto completed geological work and recommended diamond drilling. 2008: Alto Ventures drilled two holes, totaling 332 m to test sections of the Empress Structure. 2012: Alto Ventures completed sampling of the 2008 drill cores that were not sampled previously and analyzed these samples for gold plus other trace elements. Alto also completed a surface channel sampling program testing targets along the Empress Structure.

May 29, 2018 (Therese Pettigrew) - Stripped area 6E exposes a >15 m wide cross-section through the Empress structure. The rocks here consist largely of deformed and altered quartz-sericite schist. However, the intensity of deformation and alteration is greater than that observed further to the west at Area 1E. The shear fabric at this location varies in strike direction from approximately 085º at the western end of the exposure to 070º at the eastern end. The dip of the shear fabric is approximately 65º toward the south. Alteration consists of intense silicification and iron carbonatization, and the altered rocks also contain disseminated sulphide mineralization (up to 5%). Evidence of intense deformation can be seen in the eastern end of the exposure and in an old exploration trench located immediately to the east. Numerous small-scale folds are exposed at the northeastern corner of the stripped area. These folds plunge moderately toward the east, with the hinge of one fold measured at 078º/35º. The fold axial planes appear to parallel the Empress structure foliation. Quartz veins, which show pinch-and-swell characteristics throughout the deformation zone, also swell noticeably toward the eastern end of the stripped area (in the area of most intense deformation, and where the highest gold values have been reported). The quartz vein material at this stripped area typically contains disseminated sulphides (Puumala et al., 2016). Cameco 9+00, located at NAD83 Zone 16 502365 m E, 5412540 m N assayed 3.12 gpt Au. Cameco 10+75, located at NAD83 Zone 16 502525 m E, 5412585 m N assayed 1.16 gpt Au (AFRI 42D15SW2010).

Jul 14, 2016 (Andrew Tims) - Trench 6E averaged 1.3 g/t gold across a 16.2 m wide section of the Empress Shear.
May 29, 2018 (Therese Pettigrew) - A number of grab samples of sulphide-mineralized quartz vein material and host rocks were collected by Resident Geologist Program staff from Area 6E. All samples returned anomalous gold values, ranging from 53 ppb to 12,652 ppb Au, and the highest assay (12.6 g/t Au) having been returned from a sample (15DCEP006) collected from the southeastern portion of the stripped area, near the locations where Cameco and Alto Ventures have reported their best channel sample results (Puumala et al., 2016).
