Cobalt Blue Holdings Puts Refining at Centre of its Critical Minerals Strategy

Kwinana First, Broken Hill Later

A key point in Cobalt Blue’s recent corporate materials is sequencing.

According to the company profile and investor presentations, the company is aiming to develop the Kwinana Cobalt Refinery first, followed by the Broken Hill Cobalt Project. That order is notable because it places refining and processing infrastructure at the front of the development plan, rather than treating it as a later-stage addition to a mining project.

For a market increasingly focused on where critical minerals are processed, not just where they are mined, that strategy gives investors and industry observers a clearer sense of how Cobalt Blue sees its role in the sector.

The company has also pointed to its Broken Hill Technology Centre as part of that plan, with the facility intended to help demonstrate and validate processing technology and feedstock options. In practical terms, that means the technology centre sits between concept and commercial development, supporting the company’s refining ambitions with technical work.

Broken Hill Central to Long-Term Picture

Although Kwinana is being prioritised, Broken Hill remains a central asset in the company’s portfolio.

The Broken Hill Cobalt Project in NSW underpins Cobalt Blue’s original identity as a cobalt-focused developer. While the company is currently placing emphasis on downstream refining, Broken Hill still provides the longer-term mining component of the broader strategy outlined in company materials.

That combination—mine development plus refining capacity plus technology validation—is what gives Cobalt Blue a different profile from explorers focused only on discovery or resource growth.

Refreshed Halls Creek Scoping Study

Outside cobalt, Cobalt Blue holds a 51% earn-in interest in the Halls Creek Project in WA, encompassing the Onedin and Sandiego deposits.

The project received a major update following the release of a refreshed Scoping Study, injecting robust economics and a clear development blueprint into the company's secondary portfolio.

The Refined Concept

Feedstock material from two nearby deposits. Onedin (open cut) and Sandiego (underground), will be mined in sequence and treated via heap leaching using a common processing plant at Onedin.

The flowsheet targets the production of copper cathode, zinc oxide and silver doré, with silver recovery evaluated as a third revenue stream for the first time.

Management notes that the common processing plant also acts as a scalable platform for district-wide growth, with future assessments set to examine regional feedstocks to extend mine life and optimise project economics.

Project Economics (100% Basis)

• Pre-tax NPV10 of A$317 million and a pre-tax IRR of 47%.
• Initial capital expenditure estimated at A$75 million, with a rapid payback period of approximately 3 years.
• Production profile averaging roughly 4,000 tonnes of copper, 13,000 tonnes of zinc and 130,000 ounces of silver per annum over an ~11-year mine life.
• A diversified revenue mix weighted 56% to copper, 37% to zinc and 7% to silver, underpinned by a conservative long-term price deck (US$13,000/t copper; US$3,100/t zinc; and US$50/oz silver).

While cobalt remains the primary strategic theme for the group, Halls Creek adds a complementary operational engine. The project provides shareholder exposure to electrification and data-centre-aligned metals (copper, zinc and silver) while serving as a practical demonstration of the Broken Hill Technology Centre's technical capabilities in applying proprietary processing innovations to third-party assets.

What Recent Company Materials Show

Cobalt Blue has released a series of presentations over the past year, including its June 2025 corporate presentation, September 2025 corporate presentation, November 2025 AGM and conference presentations, December 2025 investor presentation, and further corporate updates in January, April, August and November 2026.

Taken together, those materials show a company continuing to present itself as part of the critical minerals and battery materials supply chain, with refining at Kwinana, project development at Broken Hill, and now advanced base-metals scoping at Halls Creek forming the pillars of the story.

Why Cobalt, Processing, and Base Metals Matter

Cobalt remains part of the broader critical minerals discussion because it is used in battery chemistries and sits within a supply chain that many Western governments and manufacturers have been trying to diversify. At the same time, metals like copper and zinc are facing structural demand tailwinds driven by global electrification and expanding digital infrastructure.

In recent years, policy attention has increasingly shifted from raw material extraction alone to midstream processing, refining capacity and supply-chain resilience. That has created a backdrop in which projects linked to domestic or allied-country processing have attracted attention across Australia, North America and Europe.

For companies like Cobalt Blue, that macro setting is relevant because it places greater focus on how and where critical and base metals are converted into usable chemical and refined products. It also explains why recent corporate updates give prominence to the Kwinana refinery concept, processing technology work at Broken Hill, and the commercial optimisation of assets like Halls Creek.

Early-Stage Developer in a Policy-Driven Sector

Cobalt Blue is still a development-stage company. As outlined in background company information, the group has no material operating revenue and remains dependent on project development, grants, equity funding and strategic partnerships.

That places it in a category familiar to many ASX small-cap resources investors: a company with exposure to crucial commodity themes, but where progress is tied to studies, commercial arrangements, financing pathways and delivery milestones rather than current production.

For readers looking at the company for the first time, the clearest takeaway is that Cobalt Blue is not simply pursuing a single-commodity strategy. It is positioning itself as an Australian critical and base metals developer with active ambitions across downstream refining, project development, and advanced processing technology, anchored by Kwinana, backed by Broken Hill, and diversified through Halls Creek.
