Gorilla Gold (ASX:GG8) extends Mulwarrie mineralisation with 700m step-out drilling success

Gorilla Gold has reported high-grade gold intercepts from step-out drilling at its 100%-owned Mulwarrie Gold Project in Western Australia, with results extending mineralisation more than 700m beyond the current 350,000oz @ 3.6g/t Au Mineral Resource Estimate.

The announcement reinforces the scale of the system along strike and situates Mulwarrie within a broader, under-explored corridor supported by expanding geochemical anomalies.

Highlights

• Step-out drilling intersected high-grade mineralisation more than 700m from the existing MRE, including:

  • 3.4m @ 9.0g/t Au from 376.9m (MWEX115)

  • 0.7m @ 24.8g/t Au from 110.3m (MWEX111)

• Current MRE stands at 350,000oz @ 3.6g/t Au (Indicated and Inferred)

• Soil sampling has defined a ~2.5km anomaly northwest of the resource and >11km of anomalies at Mulline

• Strategic tenement acquisition for $200,000 in scrip consolidates tenure between Mulwarrie and Mulline

• Ongoing 150,000m drilling programme, with ~55,000m allocated to Mulwarrie

The latest drilling results represent the furthest step-out tests along strike to date and demonstrate continuity of mineralisation beyond the defined resource envelope.

The long section presented in the announcement shows mineralisation extending along a north-west to south-east trend, with new intercepts reinforcing the potential for further extensions outside the current resource boundary.

Geologically, Mulwarrie is positioned within a 10km wide greenstone belt forming part of the north-west extension of the Coolgardie Line.

Gold mineralisation is associated with structurally controlled quartz reefs and shear zones, with sulphide assemblages including pyrrhotite and pyrite and alteration characterised by biotite, epidote and carbonate.

Mineralisation occurs both in narrow shear-hosted zones and in broader quartz reef systems, contributing to multiple lodes extending from surface to at least 450m depth.

The broader exploration context is supported by soil geochemistry, with gold-in-soil anomalies extending beyond the current resource footprint, where only 1.3km of a 5km mineralised system has been drill tested to date and regional sampling has outlined more than 35km of anomalous strike across the Mulwarrie and Mulline corridor.

These results define a pipeline of targets across a now contiguous tenement package.

Corporate activity has aligned with this geological expansion through the acquisition of E30/561 from Hamelin Gold for $200,000 in GG8 scrip, consolidating tenure between Mulwarrie and Mulline and strengthening continuity along a prospective mineralised horizon.

The consideration will be escrowed for 12 months and calculated using a 5-day VWAP prior to completion.

Operationally, drilling remains the central driver of resource growth, with the company committed to a 150,000m drilling programme, including approximately 55,000m allocated to Mulwarrie and supported by multiple rigs currently active on site.

In parallel, studies and permitting work are underway to define a conceptual development pathway, with the scale of these activities expected to evolve alongside further discoveries.

Gorilla’s Chief Executive Officer, Charles Hughes, stated:

“Intersecting high-grade gold more than 700 metres beyond the existing resource boundary… highlights the potential to materially expand the Mulwarrie Mineral Resource through continued drilling in 2026.”

The project’s proximity to existing infrastructure, including the Davyhurst Mill located approximately 10km away and other processing facilities within trucking distance, provides operational context as exploration advances.

Looking ahead, the company’s focus remains on extending mineralisation at depth and along strike through systematic drilling, while continuing to refine targets across the broader corridor.

The combination of step-out success, expanding geochemical anomalies and consolidated tenure positions Mulwarrie as an active exploration system within the Eastern Goldfields with a defined pathway for further resource growth.
