Key Highlights

Twenty-one RC holes totalling 4,215m were drilled across two prospects.
Hole 26GWRC035: 8m at 11.5 g/t gold, including 4m at 15 g/t.
15m at 1.62 g/t gold from 154m, including 1m at 20.16 g/t.
The three companies reported drilling results.

Three ASX gold explorers released drilling results this reporting period. Austin Metals (ASX:AYT), Marmota (ASX:MEU) and Duketon Mining (ASX:DKM) each published an update that is covered below.

Austin Metals (ASX:AYT): Brunswick Hill Intersections

Hole 26BHRC006 cut 12 metres at 1.67 g/t gold starting at 21 metres, containing a 7-metre zone at 2.70 g/t and a single metre reaching 12.70 g/t. The company says the outcome supports its structural model, with gold in banded iron formation linked to northeast and northwest trending structures.

The best Mt Sandy hole, 26MSRC008, returned 4 metres at 1.07 g/t from 32 metres, while 26MSRC003 hit 2 metres at 1.61 g/t. Gold sits along a west-dipping shear on the upper contact of a high-titanium dolerite sill, a setting the company compares with two known high-grade Western Australian deposits.

Marmota (ASX:MEU): Batch 2 Results

Most extension holes to the northeast met high-grade gold. 26GWRC035 cut 8 metres at 11.5 g/t including 4 metres at 15 g/t, and 26GWRC034 cut 8 metres at 10 g/t including 4 metres at 18 g/t. Other holes include 12m at 4.5 g/t and 4m at 12.5 g/t.

Batch 1 covered the southern Mainwood zone. With both ends now reporting, Marmota says high-grade gold has been followed almost continuously from within 16 metres of the surface, doubling the identified high-grade strike.

Duketon Mining (ASX:DKM): Astro Intercepts

Results include 15m at 1.62 g/t from 154m, 8m at 2.60 g/t from 50m (4m at 4.50 g/t), 4m at 1.01 g/t, 15m at 0.77 g/t, 3m at 1.47 g/t and 2m at 1.54 g/t.

The 20.16 g/t metre sits at about 130m vertical depth. Mineralisation spans over 450m of strike within a 1.8km UltraFine+ soil anomaly.

Why These Updates Could Matter

Austin Metals: Early RC drilling of this kind decides which prospects earn more drill metres. Marmota: Linking both ends creates a continuous corridor rather than isolated hits, widening the area any future resource would cover. Duketon Mining: The soil anomaly is about four times the drilled strike, outlining area left to test.
