The mineralization is related to silica rich listwanite and dolomite rock units as well as with smaller zones of jasperoid developments.
Numerous historical gold showings that lie on trend from Clarks Brook have strong epithermal characteristics including jasperoid development, silica sinters and pathfinder elements such as antimony and arsenic.
The 2019 program objectives are: completion of the South Railroad PFS for the Dark Star and Pinion oxide gold deposits; step out drilling to the east and south of the Dark Star deposit to test for resource expansion potential; exploration drilling of high-value targets at Hidden Star, Jasperoid Wash, Dixie, LT, Ski Track and North Bullion; and in the northern portion of Dark Star, drill testing a newly recognized deep feeder-style target beneath the oxide resource.
Bureau of Land Management ("BLM") approved a Plan of Operations permitting exploration activities on the core group of claims at Kinsley, Pilot Gold has been drilling and constructing road access in three key areas, including the Western Flank, Candland Canyon and the Ken Jasperoid target.
Gold and silver occur within a jasperoid developed along the contact of Mississippian age Joana limestone and Chainman shale.
Specific standards used for the best fit regression calibration for elements of interest include G-2 (basalt), AGV-1 (andesite), GSP-1, SY-2 (syenite), BHVO-1 (hawaiite), STM-1 (syenite), QLO-1 (quartz latite), RGM 1 (obsidian), W-2 (diabase), BIR-1 (basalt), SDC-1 (mica schist), TLM-1 (tonalite), SCO-1 (shale), GXR-1 (jasperoid), all U.S.
Occurrence: In brecciated and hydrothermally rounded jasperoid fragments lightly cemented by late-stage silicification.
The Cedar Hill and Russell Mountain deposits exhibit thinly laminated banded iron formation (BIF) hematite with oolitic hematite laminae and red jasperoid. The oolites at Cedar Hill and Russell Mountain laed us to the conclusion that these bedded ores are of undoubted sedimentary origin.
Float samples of jasperoid taken from the margins of the intrusive contain up to 46 grams/mt of gold.
The later events are characterised by the development of quartz/calcite/adularia veins and breccia veins, jasperoid and jasperoid breccias with epithermal gold mineralisation.
** "Mustang" - a continuation of the property's 1.5 km long gold-in-soil "Moleen", and "Willow" targets, located 600 metres north of the "Stallion Zone" (previously named the "West Zone"), and immediately south of the Jasperoid Wash zone discovered by Gold Standard Ventures ("GSV")
