Exploration History

1934: Lake Rowan Gold Mines Limited carried out trenching. 1945-46: Lake Rowan Mines Limited carried out geological mapping and drilled thirty-five diamond drill holes totalling approximately 6500 m, discovering the Creek Zone. 1951: Rowan Consolidated Mines Limited. 1974: Rowan Gold Mines Limited (subsidiary of Dickenson Mines Limited). 1975: Cochenour Explorations completed mag and HLEM surveys. 1983: Goldquest Explorations Inc conducted a radiometric survey. 1983-85: Goldquest completed lithogeochemical survey, stripping, washing, detailed mapping and sampling on the Martian Bay Property. 1989: Chevron Minerals Ltd, completed geological mapping and rock sampling. 2000: Goldcorp completed helicopter-borne mag, electromag, VLF and radiometric surveys. 2006: King’s Bay Gold Corp. optioned the property from Goldcorp and drilled 9 DDH totalling 1370.4 m. 2007: Hy Lake Gold optioned the Rowan property from Goldcorp.

Geology Comments

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: On these claims in the areas southwest and northeast of Rowan Creek, thick felsic tuffs and a unit of mafic lava interfinger with chert-magnetite iron formation, chert beds, clastic sediments and graphitic material (Bishop 1934). Prospecting uncovered three significant mineralized occurrences here, known as numbers 1, 2, and 3 prospects. Bedding strikes roughly N65 deg.E but shearing strikes about N80deg.W and dips sub-vertically. Bishop (1934) reports that the occurrences consist of wide mineralized shear zones in the felsic tuff, containing quartz veins up to 25 cm thick, plus disseminations and streaks of pyrite, chalcopyrite, sphalerite and arsenopyrite. Lake Rowan Mines Limited (1946,1957) conducted an intensive diamond drilling program in this 'creek zone' and assayed many mineralized core sections of sheared and silicified felsic tuff, and of iron formation. DEPOSIT DESCRIPTION: This 1100 m long, northeast-striking zone of interlayered volcanic rocks and chemical sediments contains many mineralized sections that reportedly carry gold.

Mineralization

Mineralization Comments

Mar 19, 2012 (K R Kettles) - MDI1 DATA: GRADE 1946 - 35 DDH'S: TYPICALLY A DDH CONTAINED 4/5 INTERSECTIONS, 1/2 M LONG, 0.03-0.10 OPT AU, GRADE 1946 - DDH-30: HIGHER GRADE: UP TO 0.80 OPT AU OVER 1.52 M, POTENTIAL (FROM OFR 5558): CREEK ZONE MAY HAVE POTENTIAL AS A HIGH TONNAGE/LOW GRADE GOLD DEPOSIT Many mineralized intersections were obtained by Lake Rowan Mines Limited (1946). Typically a given drill hole contained 4 or 5 intersections, each being 1 or 2 m long, and grading from 0.03 to 0.10 oz/ton (1.029 to 3.429 g/tonne) Au. Higher- grade intersections were obtained, up to 0.80 oz/ton (27.428 g/tonne)Au over 1.52 m in DDH# 30. From these results it appears that this Creek Zone may have potential as a high tonnage/low grade gold deposit. 2007 2 DDh in the area, assays returned uncluded 0.47 g/t Au over 1 m , and 1.08 g/t over 1.5 m

Oct 30, 2020 (Therese Pettigrew) - The Creek Zone is the SW-extension of the Porphyry Hill Zone and occurs along the irregular northern contact of a large quartz porphyry sill and iron formation. Area is strongly carbonatized and cut by numerous quartz stringers. Pyrite is ubiquitous and the best gold values are associated with disrupted iron formation. In the Porphyry Hill Zone, gold is found in sheared, sulphidized iron formation and in shear-parallel quartz stringers within the adjacent felsic porphyry (Assessment report 20000003800). DDH RW-06-101 returned up to 0.046 oz/t Au over 2 feet (1.58 g/t Au over 0.6 m) from a quartz feldspar porphyry with 5-10% disseminated pyrite and pyrrhotite. DDH RW-06-102 retuned up to 0.317 oz/t Au over 2 feet (10.87 g/t Au over 0.6 m) from a brecciated and silicified intermediate-felsic volcanic with 5% pyrite and pyrrhotite. DDH RW-06-103 returned up to 0.057 oz/t Au over 1.5 feet (1.95 g/t Au over 0.46 m) from a quartz feldspar porphyry cross cut by quartz-carbonate veins. DDH RW-06-122 returned up to 0.237 oz/t Au over 1.5 feet (8.12 g/t Au over 0.46 m) from a tuff feldspar porphyry with 5% pyrite (Assessment report 20000005495).

Alteration Comments

Dec 07, 2005 (K R Kettles) - The felsic tuff is sheared and silicified in mineralized sections.
