The Harvey occurrence is located east of Atlin Lake about 13 kilometres south of the community of Atlin.
The McKee Creek area is underlain primarily by cherts and argillites of the Mississippian to Triassic Kedahda Formation (Cache Creek Complex). These are intruded by upper Mississippian to Permian ultramafic plugs (Cache Creek Complex). Mafic greenstone of the upper Mississippian to Permian Nakina Formation (Cache Creek Complex) underlies the Kedahda Formation and some exposures are found at lower elevations.
North trending shear zones, developed in chert and ultramafic rock, were exposed by hydraulic placer mining in McKee Creek, just below its confluence with Eldorado Creek. The Ore zone is 25 metres wide and of unknown length. A second similar zone is present about 150 metres to the northeast of the first. The zones are characterized by pervasive carbonate alteration (listwanite?) of the ultramafics and by intense weathering to red and yellow clay and blue chloritic mud. Blue mariposite coatings occur on fault breccia fragments.
Quartz stockworks occur in the shear zones and host disseminated pyrite, arsenopyrite, and minor galena and chalcopyrite. Chip samples taken on the shear zone did not contain significant quantities of gold.
In 2008, a drillhole (MK8-3) located about 650 metres northwest of the original Harvey showing intersected gold mineralization at depth. The hole was designed to test two distinct targets. The first, a listwanite-altered zone of quartz veining/silicification was planned to be intersected at shallow depth. This zone accompanies a tight, north-northwest striking, steep fault. The second target, designed to be intersected at greater depth, is a zone of strong listwanite alteration situated across McKee Creek approximately 300 metres upstream from its confluence with Eldorado Creek. The hole successfully intersected both zones, although the grades and character of encountered gold mineralization were disappointing; the best intersected interval yielded 1.12 grams per tonne over 0.81 metre (Assessment Report 30818).
In late 2006, Saturn Minerals Inc. optioned the McKee Creek property and became the operator. In 2007, Saturn Minerals completed a rock sampling program which was accompanied by detailed lithological and structural observations; a total of 122 rock samples were sent for analysis. In 2008, Saturn conducted a complementary rock sampling program where a limited number (30 samples) of chip and grab samples were collected from the areas previously sampled in 2007. Four diamond-drill holes totalling 694.03 metres were drilled to test a few selected gold targets located during the Company's 2007 reconnaissance rock sampling program. A total of 171 core samples were collected and shipped for analysis.
