Anchorage – – September 16, 2026 -- PolarX Limited (ASX: PXX; OTCQB: PXXXF) reported assay results showing copper grades as high as 14.1% over multi-metre intervals from its Caribou Dome Project in Alaska, part of the Alaska Range Joint Venture with Northern Star Resources Limited.

Drill hole CD26-007 returns 24.8 metres at 9.8% copper

Hole CD26-007 intersected 24.8m grading 9.8% Cu and 14.5g/t Ag from 2.4m depth, including a higher-grade section of 4.4m at 14.1% Cu and 16.9g/t Ag from 11.7m. A separate interval within the same hole returned 4.9m at 13.6% Cu and 20.4g/t Ag from 6.6m.

Hole CD26-004 delivers 22.6 metres at 8.1% copper near surface

CD26-004 intersected 22.6m at 8.1% Cu and 13.5g/t Ag starting from 3.7m, including 5.8m at 12.4% Cu and 21.3g/t Ag from 11.1m. Additional narrower intercepts were logged in holes CD26-003 and CD26-006, ranging from 3.2% to 3.5% Cu.

Dubai and Nouakchott – September 15, 2026 -- RAMINVEST HOLDING is moving into a targeted drilling phase at its Wompou gold project in Mauritania after assay results returned grades of up to 50.14 grams per tonne of gold. Six priority targets, labeled T-01 through T-06, have been defined for the initial test-drilling campaign.

Assay results confirm high-grade gold zones across the Wompou permit

The Wompou site spans 446 square kilometers within the Mauritanides belt and is held by the Group's Mauritanian subsidiary under exploration permit No. 2265B2. Statistical analysis found a strong correlation between arsenic and gold (R = 0.989), validating the use of arsenic as a pathfinder element to refine drill targets.
