The Sheep Creek Gold District is an orogenic gold district with historical gold production of almost 800,000 ounces at an average gold grade of 14.4 g/t. Margaux Resources has consolidated the claims in this district for the first time ever, to allow systematic, modern exploration of the 10 km long prospective belt.
A recent Geoscience BC Report has shown that veining at Sheep Creek is analogous to that in the Barkerville area. In contrast to Barkerville, the Sheep Creek Gold District has had minimal modern exploration since mining ceased in the early 1950’s.
The area is underlain by sequence of Cambrian metasediments, including argillite, quartzite and limestone, which are intruded by two separate intrusive events, one in the mid-Jurassic and the other in the Cretaceous. As a result of Jurassic accretion, the sediments have been folded into major anticline/syncline pairs with north-trending axial planes. Veins formed in the final stages of the accretion event, and are preferentially hosted within more brittle units within the metasedimentary sequence, or within pre-vein Jurassic intrusives.
In 2017, Margaux completed 19 hole (4039 m) diamond drill program on the Sheep Creek Gold District. Drilling was designed to test a variety of wide spaced, big-picture targets, as opposed to close-spaced definition-type drilling on a single vein. Targets tested in 2017 include: new veins with no previous drilling and no historic production (Maggie Aikens, Kat), the at-depth continuation of veins below the depth of historic mining (Bayonne, Bluestone), and conceptual blind-vein targets in brittle units, at depth in the core of anticlines. The program was highly successful. At least one promising new vein was discovered which requires further drilling. Gold grades were confirmed from 2 previously undrilled targets. Two veins were also shown to continue to depth, with good gold grade, below the limit of historic mining (Bayonne Main, A vein).
Approximately 8000 m of drilling is planned for 2018 to follow-up on the 2017 results and to test additional high-priority targets.
Veins in the Sheep Creek Gold District are high-grade, steeply dipping, sub-parallel, low-sulfide quartz veins. Individual veins averaged approximately 1 m in width and were mined over strike lengths up of up to 550 m and up to 500 m depths.
