Bulgera Resource Swells to 501,000 Ounces as Norwest (ASX: NWM) Advances Strategy for Gold

Key Highlights

• Norwest Minerals (ASX: NWM) lifts Bulgera Gold Project resource to 501,000 ounces
• Heap leach tests deliver gold recoveries as high as 92%
• Rapid extraction rates and low reagent consumption strengthen economics
• Company advances development pathway amid record Australian gold prices
• Shares rise 8.33% in Friday trade

Gold miners have spent the past year chasing one powerful idea.

Can lower-grade deposits become highly profitable in a world where gold prices are hovering near historic highs?

For Norwest Minerals (ASX: NWM), the answer increasingly appears to be yes.

The junior explorer on Friday delivered a significant technical update from its Bulgera Gold Project in Western Australia, confirming strong metallurgical recoveries while simultaneously expanding the project’s mineral resource to more than half a million ounces.

Shares in Norwest Minerals (ASX: NWM) climbed 8.33% to 1.3 cents in afternoon trade as the market responded to what many see as a major de-risking event for the company’s long-term development ambitions.

At the centre of the update was one critical outcome.

The gold is proving easy and relatively cheap to extract.

Recoveries above industry benchmarks

For mining investors, resource size alone is rarely enough.

The real question is whether the metal can be recovered economically.

That is where Norwest’s latest test work stood out.

Heap leach metallurgical testing at Bulgera returned gold recoveries ranging between 86% and 92%, well above the roughly 70% benchmark generally considered commercially viable for heap leach operations.

The standout result came from transition ore crushed to 12.5 millimetres, which delivered a 92% recovery rate.

Oxide material returned recoveries between 86% and 89%.

Equally important was the speed of extraction.

Norwest said approximately 75% to 80% of the gold was recovered within the first 72 hours, suggesting rapid leach kinetics that could improve operational efficiency and shorten processing times.

The company also highlighted exceptionally low reagent consumption during testing, reporting cyanide use of just 0.38 kilograms per tonne and lime consumption of 1.3 kilograms per tonne.

In simple terms, that points to lower operating costs.

And in mining, costs often determine whether a project survives downturns or becomes highly profitable during commodity booms.

Chief executive Charles Schaus said the results strongly support the company’s preferred development strategy.

“These metallurgical results are exactly the combination we look for in a commercially robust heap leach operation,” Schaus said.

“We are rapidly building the technical foundations needed to advance Bulgera toward a development decision.”

Why heap leaching matters in today’s gold market

Heap leaching has become increasingly attractive as gold prices surge.

Unlike traditional carbon-in-leach processing plants, heap leach operations generally require significantly lower upfront capital and simpler infrastructure.

That can dramatically reduce development risk for smaller companies.

Instead of constructing expensive mills and processing circuits, miners stack crushed ore onto lined pads and slowly recover gold using chemical solutions.

The trade-off is that heap leach projects typically work best on deposits with lower grades but large tonnage.

That dynamic is now working in Norwest’s favour.

The company revealed the Bulgera resource has expanded to 23.8 million tonnes grading 0.65 grams per tonne gold for 501,000 ounces.

The increase was largely driven by lowering the project’s cut-off grade from 0.6g/t to 0.24g/t under updated economic assumptions tied to the current gold environment.

Australia’s gold price has surged toward A$5,000 per ounce in recent months, fundamentally changing the economics of many deposits previously considered marginal.

Material once classified as waste can suddenly become profitable ore when gold prices rise sharply.

That shift is now reshaping development strategies across Australia’s junior mining sector.

A changing tone from exploration to development

The language inside Friday’s update also reflected a subtle but important transition.

Norwest is increasingly talking less like a pure explorer and more like an emerging developer.

The company confirmed additional column leach tests are underway to simulate full-scale heap conditions and help finalise future pad design and operating cost estimates.

Environmental and engineering groundwork is also progressing.

Importantly, the proposed heap leach facility sits within an area already disturbed by historical mining activity.

That may simplify future permitting and environmental approvals compared with greenfield developments.

Around 71% of the tested near-surface material also falls within the higher-confidence “Indicated” resource category, giving the company greater certainty as it advances technical studies.

Gold’s resurgence reshaping the junior sector

Norwest’s timing also reflects a broader shift taking place in global commodity markets.

While battery metals and lithium stocks have cooled following years of rapid growth, gold has quietly regained momentum as geopolitical tensions, inflation concerns and central bank buying continue supporting prices.

According to the World Gold Council, central banks globally purchased more than 1,000 tonnes of gold for a third consecutive year in 2025, reinforcing demand for safe-haven assets.

At the same time, many major producers are struggling with declining reserve grades and rising operating costs.

That has increased market attention on smaller developers capable of bringing lower-cost ounces into production.

For Norwest, Bulgera may now be entering that conversation.

The project is still at a relatively early stage compared with established Australian gold operations, but Friday’s results suggest the technical pathway forward is becoming clearer.

Schaus said the company remains focused on systematically progressing the project.

“The combination of strong recoveries, fast leach kinetics and low reagent consumption gives us increasing confidence in Bulgera’s development potential,” he said.

A project beginning to take shape

Junior mining stories often rise and fall on one central question.

Can the geology become a business?

For Norwest Minerals (ASX: NWM), Friday’s update suggested Bulgera may be steadily moving closer to that transition.

The company now has scale, encouraging metallurgy and a development model aligned with today’s elevated gold market.

And in a sector where many projects stall long before production decisions arrive, proving the economics early can often matter just as much as finding the gold itself.
