Golden Deeps (ASX: GED) Hits 680g/t Silver at New Namibian Target. Could South Ridge Rival Graceland?

A second high-grade exploration target is emerging for Golden Deeps Limited (ASX: GED) in Namibia, with rock-chip sampling at South Ridge returning up to 680 grams per tonne silver and 12.57% zinc.

The results, reported on 10 November 2026, expand the company's exploration potential beyond its established Graceland prospect. However, the critical question is whether Golden Deeps can convert promising surface mineralisation across multiple targets into substantial, economically viable deposits.

Key Numbers Behind the Latest Discovery

• 680g/t silver: Peak silver grade from South Ridge rock-chip sampling, accompanied by 6.67% zinc and 2.07% copper.
• 12.57% zinc: Another high-grade surface sample, containing 98g/t silver.
• 132 samples: Collected across a mineralised corridor extending approximately 1km by 400m at South Ridge.
• 9.2% copper and 417g/t silver: Previously reported peak assay grades at Graceland.
• $3.548 million: Cash reserves at 30 September 2026, following $670,000 in quarterly net expenditure.

The Latest Development: A Second High-Grade Target Emerges

Golden Deeps has identified significant copper, silver, zinc and lead mineralisation at South Ridge within Namibia's Otavi Mountain Land.

Sampling outlined a northeast-trending corridor approximately one kilometre long and 400 metres wide, reinforcing earlier soil geochemistry results.

Notable rock-chip samples included 279g/t silver with 3.3% copper, alongside another returning 11.19% zinc, 97g/t silver and 2.1% lead.

The company interprets the mineralisation as associated with hydrothermal alteration and brecciation, geological characteristics potentially consistent with the region's historical polymetallic deposits.

South Ridge lies along the broader Pavian mineralised trend, which also hosts Golden Deeps' Border inferred mineral resource of 16.2 million tonnes grading 2.12% combined zinc and lead and 4.76g/t silver.

That existing resource provides regional geological context, but does not establish a mineral resource at South Ridge.

Importantly, rock-chip sampling is selective and cannot establish representative grades, mineralised thicknesses or economic tonnage.

What Stands Out: Two Targets, One Funding Challenge

The emerging South Ridge opportunity arrives while Golden Deeps advances deeper drilling at Graceland.

Three diamond holes beneath Gossan 1 have intersected visually identified disseminated copper and zinc mineralisation within targeted geophysical anomalies.

Laboratory assay results are expected within four to six weeks of the November update.

Drilling has also commenced at Gossan 1 East, with subsequent testing planned at Gossan 1 Far East.

We think having multiple prospective targets strengthens Golden Deeps' geological opportunity. However, simultaneous exploration programs could increase spending before either discovery generates a defined economic resource.

At September's expenditure rate, the company's cash balance represented approximately 5.3 quarters of funding, although expanded drilling could shorten that runway.

What Golden Deeps Is Doing Now

Golden Deeps plans channel sampling and trenching across South Ridge's strongest mineralised zones, followed by shallow diamond drilling.

Further induced polarisation surveying may identify deeper sulphide targets.

Meanwhile, drilling at Graceland is investigating whether high-grade near-surface mineralisation extends into larger sulphide systems.

These programs could support future resource definition, but require additional drilling, geological modelling and metallurgical evaluation before development economics can be assessed.

Insight: Could Two Discoveries Transform Golden Deeps' Asset Value?

We think South Ridge meaningfully improves Golden Deeps' exploration optionality, particularly given its proximity to an established mineralised trend. However, the market should distinguish attractive surface grades from commercially recoverable resources. Graceland remains the more advanced test of the company's geological strategy, while South Ridge adds a second opportunity requiring systematic drilling. With limited cash relative to potential development requirements, exploration discipline will be essential. A defensible valuation depends on demonstrating deposit scale, metallurgical recovery and credible project economics, rather than extrapolating isolated high-grade samples.

What Happens Next?

The immediate catalyst is laboratory assay results from Graceland's deeper diamond drilling, expected in the coming weeks.

At South Ridge, channel sampling and subsequent drilling will determine whether surface mineralisation continues beneath the outcrop.

Together, these results could materially strengthen Golden Deeps' exploration portfolio or expose limitations in mineralised continuity.

For shareholders, the crucial issue is whether Golden Deeps can establish economic scale across its Namibian discoveries before further exploration expenditure creates a need for additional capital.
