1942-43 - W.B. Milner conducted numerous trenches and open cuts tracing the skarn 80 metres along a north-south strike. Two bands of skarn are separated by a greenstone unit. Numerous W03 values reneging from 0-1% to 1% occur over variable widths.
1943 - The Strategic Metals Committee part of the Wartime investigation for Tungsten drilled 14 diamond drill holes over a 100 metre strike length. Eight holes intersected a weighted average of 0.312% W03 over an average width of 25 feet. No samples were assayed for gold or copper. The deposit was considered too low grade with poor continuity of scheelite mineralization.
In 1948 - W.E. Cockfield described the deposit as having an exposed length of 350 feet (actual length concealed by overburden at both ends), with width ranging from 25 feet to 75 feet, averaging 40 feet. On this basis he estimated a "mineral zone of approximately 1,400 tons per foot of depth and the deposit shows no change in character to a depth of 190 feet". Surface samples by Buffam averaged 0.25% W03, but Hedleys samples included raised the weighted average grade to 0.28% WO3. Results from drillholes 4,5,9,10,11,12,13, and 14 gave an average of 0.217% WO3 across an average of 25 feet. Copper and precious metals were not assayed at that time.
1958-65 - Torwest Resources Ltd. conducted work including trenching, geophysical, geochemical and geological surveys. Two or more drill phases on the Lucky Mike, skarn zone. 23 or more holes over 150 metre strike length. Based on these programs plus 1943 data, Torwest defined two east dipping tungsten-skarn bodies. Consulting Engineer C.H. Donaldson estimated "drill-proven" reserves for the Lucky Mike deposit of 350,000 tons grading 0.56% copper, 0.30% W03, and 0.60 oz/ton silver. (SMF for Brendon Resources Ltd. dated July 12, 1973, reported in Bulletin MR 223, 1989, Deposit BC 133.).
1988 - Corona Corporation conducted an exploration programduring which culminated in a localized drilling program centred on the Lucky Mike deposit. In connection with this program, a comprehensive airborne geophysical survey was completed over what is now the southern half of the Rey Lake property. Corona could not conclude an agreement with the owner of adjacent ground to the Lucky Mike claim, and allowed their options to lapse.
