London BTC Company Limited (LSE:BTC, OTCQB:VINZF) announced on 5 October 2026 initial on-site pXRF results from its Black Star gold-critical minerals project in Pershing County, Nevada. A maiden programme collected 69 rock-chip samples along a 2.5km corridor between the Western and Eastern targets. pXRF readings showed antimony up to 0.44% Sb, copper up to 30.0% Cu, bismuth up to 0.73% Bi and silver up to 811 ppm Ag, with the antimony-copper association appearing at both ends of the corridor. The signature mirrors a historical 1985 sample 120m south of the claims (>1% Sb, 2% Cu, 700 ppm Ag). Earlier due-diligence sampling returned up to 16.23 g/t gold and 50.5 g/t silver. Samples are now with MSALABS for laboratory assays, with full multi-element geochemistry including antimony, tungsten and copper to follow. Copper, as a by-product credit, adds strategic appeal under US critical-minerals policy, though results remain preliminary field readings.

Kantra Copper Limited (ASX:KAN) reported underground diamond drilling at its Kanmantoo copper mine in South Australia that extends the Nugent lode 70m below the 2025 Mineral Resource Estimate and 370m beneath the current 950 Level stopping horizon. Hole 26KVUG0949 returned 70m at 1.18% copper and 0.24g/t gold from 507m, including 38m at 1.46% copper and 0.18g/t gold. Nugent, on the deposit's south-western edge, carries generally higher gold grades. By end-August 2026 the company had completed 38,535m of underground diamond drilling, including 12,024m at Nugent, and expects a resource update incorporating about 80,000m of drilling in late October. Kanmantoo is an operating mine that produced 3,170t of copper in the June 2026 quarter; 2026 guidance is 12,750-14,000t of copper, and the deep extension offers low-capital growth from existing infrastructure.

Indonesia and Chile proposed a Green Minerals Partnership to deepen cooperation in copper, aluminium, battery materials, green mining technology and downstream processing, supported by the IC-CEPA.
