Exploration in the Fort Hope Area began in the 1920s with the discovery of the Fort Hope Gold Mine by prospectors in 1927. Shortly after, additional gold showings were uncovered, including at the Rich Lake Patricia showing. 1929: Mapping - Burwash (1930). 1942: Mapping - Prest (1944). 1969: Thurston and Carter completed an ODM helicopter reconnaissance survey of the Fort Hope Area. 1978: Wallace completed a detailed mapping program of the Opikeigen Lake area for the Ontario Geological Survey. 1981: Extensive sampling of existing trenches. 1984: Detailed geological mapping and grid-controlled rock geochemistry. 1985; ground MAG, VLF-EM - Kerr Addison Mines. 1986: 2 DDH, Aerodat Ltd. Flew a combined airborne MAG, EM - VLF-EM - Kerr Addison Mines. Noramco Exploration Ltd. began a 3 year exploration program on behalf of Pure Gold Resources Inc. and Golden Lake Inc. (later Ella Resources). Noramco completed extensive ground and airborne geophysical surveys, geological mapping and a 5 DDH program. 1987: Noramco completed IP and HLEM-surveys as well as a 12 DDH program totalling 2643.9 m which led to the discovery of the Zones 12 and 29 gold occurrences. Prospecting along trend led to the discovery of the Zone 41 occurrence.1988: Noramco did a magnetometer survey, a humus geochemical survey, airborne RM-VLF survey, trenching, channel sampling, prospecting and geological mapping. A 34 DDH program totalling 6259.5 m was completed, 50% of which were on Zones 12, 29 and 41. 1989: A 6 DDH program totalling 908.4 m was completed, targeting Zones 12, 29, and 41. 1997-9: SLAM Exploration (on behalf of Pure Gold and Ella Resources) conducted an exploration program including a VLF-EM survey, mag survey, rock and soil sampling, geological mapping, and prospecting. 2000: SLAM drilled 6 DDH totalling 1242.5 m, 2 of which were on Zone 12 and 1 was on Zone 29. 2003: Airborne survey was released by the province of Ontario under Operation Treasure Hunt. 2008: SLAM drilled 9 DDH totalling 910.7 m; 2 holes were on Zone 12 and 7 were on the Fort Hope Gold Mine. 2010: 4 DDH totalling 1148.92 were drilled on Zone 12. 2011: Slam and Beatrix Ventures contracted Geotech Airborne Solutions to fly a helicopter borne magnetic gradiometer geophysical survey.

Aug 18, 2014 (Mark Puumala) - According to Lemaitre (1997, AFRI 52P09NE2001), Noramco Explorations advanced diamond drill hole OL-87-18 to test HLEM and IP geophysical anomalies associated with a magnetic feature. The drill hole intersected 2.70 g/t Au over 0.5 m in chloritic tuff hosted within a thick sequence of felsic to intermediate pyroclastic rocks. The mineralized horizon is also reported to contain 20% sulphides interpreted to be a mixture of pyrite and pyrrhotite. This occurrence is located approximately 100 m north of an east-northeasterly striking fault that was mapped by Hall (2005), and is along strike with the Rich Lake occurrence, 2.6 km to the west.
