Significant Sediment Hosted Copper Zone Identified In Southern California
K2 Gold Corporation (TSXV: KTO) (OTCQB: KTGDF) has discovered a significant zone of copper mineralisation at the Stega target on the western side of the company’s Mojave project in Southern California.
A total of 99 rock chip and grab samples were collected on the Stega target with 53 samples collected along the Stega copper zone.
Highlights:
- Discovery of significant sediment hosted copper zone at the Stega target.
- Samples of up to 14.2% copper with mineralization associated with locally anomalous gold and silver.
- The Stega Copper Zone is up to 250m in width, 1.8km in length, and is open to the N-NW.
“The discovery of a significant high grade copper zone on the western side of the Mojave project is an intriguing development and speaks to the overall mineral potential of the property,” President and CEO, Stephen Swatton, said.
“Although we were aware that copper was reported from Stega we were surprised at the extent and grades of the mineralisation. We look forward to following up on these preliminary copper results – a mineral of critical importance to the clean energy transition.”
Stega Target
The Stega target is located on the western side of the Mojave property, approximately 3.4km NW of the Newmont target, covering a 1.5km x 2km NW trending zone of alteration and mineralisation in strongly folded and faulted Triassic siltstone, limestone, and shales with at least two generations of porphyritic sills and dikes.
The mineralisation is interpreted as intrusion-related and shows strong similarities to polymetallic skarn, replacement, and/or structurally controlled mineralisation in the Cerro Gordo district, 5.5km to the north.
Stega Copper Zone
A total of 99 rock chip and grab samples were collected on the Stega target with 53 samples collected along the Stega Copper Zone. The sampling was conducted to follow up on historic high-grade copper samples (>1%) and evaluate the target for further exploration.
Individual results from the programme ranged from trace to 14.2% copper and the copper mineralisation is associated with locally anomalous gold (up to 0.18 g/t Au) and silver (up to 72.9 g/t Ag). The highest-grade mineralisation is associated with a series of N-NE trending structures over a 200m wide zone with silicification, quartz veining, strong malachite-azurite-hematite, and, locally, semi-massive chalcopyrite. Individual structures are typically 1-5m in width with alteration and anomalous copper mineralisation (>0.05%) extending up to 30m from the structures.
Combined with historic sampling, the copper zone is up to 250m in width, 1.8km in length, and is open to the N-NW. Including work by the company, 247 samples have been collected on the Copper Zone and includes 28 samples >1% Cu and 68 samples >0.1% Cu (up to 15% Cu).
Numerous historic workings occur along the trend and additional work is in progress to fully evaluate the zone and identify potential drill targets including geologic mapping, soil sampling, continuous chip-channel sampling, and heliborne EM-resistivity (VTEM), magnetic, and radiometric surveys.
A VTEM (+ magnetics and radiometrics) geophysical survey has also recently been completed over the Mojave property, and is currently being processed. The survey consisted of 1036 line-km on 50m spaced lines and covered all known target areas on the property.
