Bobcat Target

Bobcat Target

The copper-gold Bobcat Target is located 4.5 km southeast of the advanced-stage Tiger Gold deposit, within the 100% owned Rau Project, at the western end of the Rackla Gold Property.

The objective of the phase one 2018 exploration program at Bobcat was to follow up on rock samples collected in 2010 and 2012 that assayed 7.37 g/t gold with 5.90% copper and 13.7 g/t gold, respectively. Two days of mapping and prospecting confirmed the presence of skarn alteration and mineralization likely associated with the under-explored Rackla Pluton 1.5 km due west.

2018 Bobcat Highlights

  • Preliminary hand pitting returned numerous multi-gram gold and multi-percent copper grab samples; including 6.07 g/t Au with 7.41% Cu and 5.08 g/t Au with 3.69% Cu;
  • Open ended 1.5 x 2 km multi-element soil geochemical anomaly associated with a large magnetic low; and,
  • Previous drilling 1 km to the west encountered elevated gold mineralization in potassic-altered granodiorite and skarn similar to that found at Bobcat, but did not receive follow-up drilling.

Bobcat Geology

The Bobcat target is situated below treeline in a moderately vegetated area of mostly gentle relief. Mapping in the area identified significant exposures of limestone and marble, which boundaries remain open. These outcrops lie roughly 1.5 km east of the mapped surface expression of the Rackla Pluton.

The Bobcat exploration target is best defined by anomalous gold, bismuth and tin with sporadic copper highs from soil samples collected from a 1.5 by 2 km area. The Bobcat soil anomaly directly coincides with the skarn targets derived from a desktop geophysical review completed in late 2017. Prospecting near a historical 7.37 g/t gold and 5.90% copper rock sample location identified a 20 x 20 m vegetation anomaly containing abundant skarn mineral vein float from an area of altered limestone and marble bedrock.

Eleven hand-pits were dug within the vegetation anomaly and most encountered mineralized skarn vein material. Highlight Bobcat grab samples are tabulated below.

Mineralization at Bobcat is typically hosted in gold-copper bearing tremolite veins with varying concentrations of chalcopyrite and copper oxides. The mineralization is characteristic of distal, retrograde skarn alteration related to an intrusive center. Marble development mapped locally within the target area further supports a distal environment and suggests this particular locale likely represents the “marble front” or outward boundary of the skarn system. Potential deposit-scale mineralization is likely to occur to the west-northwest, between the “marble front” and the Rackla Pluton. Follow-up work around the Bobcat target and the surface exposure of the Rackla Pluton is highly warranted due to the recent prospecting results and proximity to infrastructure.
