- Aircore drilling underway at Pinjin
- Program starting in northeastern corner of drill grid
- Program of up to 225 holes for approximately 10,750m planned
- Program expected to take six weeks
Kalgoorlie Gold Mining (ASX:KAL) has had its confidence in the potential of the Pinjin target in WA boosted by the discovery of previously undocumented subcrop and outcrop during access preparation for a current drilling program.

The subcrop and outcrop of highly sheared granitic gneiss, and possibly highly metamorphosed felsic supracrustal rocks, are considered likely to be part of the highly sheared margin of the Rebecca sequence, the high-grade metamorphic host rocks to Ramelius Resources (ASX: RMS) Rebecca gold deposit, located 20 km along strike to the south.
Notably, the rock types and structures observed correlate with KalGold’s detailed geological interpretation of the region, reinforcing the company’s strong confidence in the LTZ Flexure targets.
The discovery came at the perfect time with the company kicking-off aircore drilling at the Pinjin target to test a number of previously identified targets.
The program of up to 225 holes for approximately 10,750m is centred 3.5 km to the southeast of the recently drilled Kirgella Gift and Providence gold deposits.
The aircore rig is currently drilling in the northeastern corner of the drill grid in a program designed to systematically test a regional-scale flexure in the Laverton Tectonic Zone (LTZ).
KalGold has previously identified a series of aeromagnetic features, including demagnetised zones and structural breaks, coinciding with a shift in LTZ strike from NNW-trending in the north to a north–south orientation in the south.
Significant flexures along regional-scale structures such as the LTZ are considered highly prospective, as these major reorientations in ancient stress fields can create pathways for mineralising fluids in the right geological settings.
The aircore program is expected to take approximately six weeks to complete. Additionally, RC drilling is scheduled to recommence shortly at Lighthorse to test strike extensions of gold mineralisation and follow up on gold intercepts from earlier drilling programs.
Assays results from recent RC drilling at Kirgella Gift and Providence remain pending due to extended laboratory turnaround times and will be reported to shareholders once they become available.
KAL was steady at 3.2¢ with a Mkt cap of $14.58M prior to markets opening.
