Kalgoorlie Gold Mining’s (ASX: KAL) decision to take a stake in the Pinjin project in Western Australia in 2023 looks set to provide a substantial return with the drilling of a promising discovery.

The company’s share price skyrocketed early trading after it announced that it had intersected an extensive, thick section of gold mineralisation and anomalism at the Wessex target at Pinjin.

The highlight intercepts included 28 metres at 1.27 grams per tonne gold from 36m, including 8m at 1.90 g/t gold from 44m and 8m at 2.15 g/t gold from 56m.

Thick mineralisation

“KalGold’s drill program at its Wessex prospect has delivered excellent results,” managing director Matt Painter said.

“Thick, coherent zones of shallow gold mineralisation were defined across the tenement boundary from historically recorded gold anomalism.”

“The shape, geometry and style […] display parallels with Hawthorn Resources’ (ASX: HAW) neighbouring Anglo Saxon gold deposit, located less than 1 kilometre to the north-east.”

“Mineralisation at Wessex is open along strike both to the north and south and down-dip to the east.”

KalGold intends to follow up the Wessex discovery with aircore and/or reverse circulation drilling to define the full extent of the mineralisation footprint.

Prospectivity highlighted

“These results, in addition to the shallow gold mineralisation currently being incorporated into an initial JORC Code (2012) mineral resource estimate at Kirgella Gift and Providence, highlight the incredible prospectivity of KalGold’s Pinjin project,” Mr Painter added.

To date, the gold anomalism at Wessex has been defined over an area of around 800m by 250m, including historic drill intercepts across the tenement boundary.

It remains open to the north, south and east.

Prolific zone

Located around 140km north-east of Kalgoorlie Boulder, Pinjin covers a substantial portion of the southern part of the highly-prolific Laverton Tectonic Zone that further north hosts some of the Eastern Goldfields’ largest gold mines and deposits.

The company made a move in late May 2023 to acquire a 75% interest in a strong portfolio of highly prospective gold tenements, including the Pinjin area, in the Eastern Goldfields.

The acquisition included an option to acquire a 75% interest in tenure at Kirgella and Pinjin South, at the southern end of the Pinjin goldfield, and a 100% interest in tenure at Rebecca West.

Expanded footprint

In mid-December, KalGold further highlighted its confidence in the area when it obtained a new licence at Pinjin covering 38.5 sq km from the WA Department of Mines, Industry Regulation and Safety.

The 100%-owned tenement is located east of Kirgella Gift and Providence, over a distinct regional bend in the Laverton Tectonic Zone.

Mr Painter said the discovery of gold mineralisation at Wessex confirms the company’s interpretation that gold mineralisation continues southward from the outcropping Pinjin goldfield under a thin cover of transported sediment.

KalGold aims to progressively build a mineral resource base throughout the project area that could potentially provide feed to a planned mill to the south.
