Unlocking the Julimar Deposit: Chalice Mining’s Critical Minerals Breakthrough

Understanding Chalice Mining and the Julimar Deposit: Australia's Critical Minerals Breakthrough

The Julimar deposit represents one of Australia's most significant mineral discoveries in decades. Located approximately 70km northeast of Perth, this discovery by Chalice Mining (ASX:CHN) in March 2020 marked the largest nickel sulfide find globally in over 20 years and the most substantial platinum group elements (PGE) discovery in Australian history. The initial drill hole that intersected significant mineralization transformed what was previously an overlooked exploration area into a world-class mineral resource.

What is the Julimar Deposit and Why is it Significant?

The Discovery That Changed Everything

The Julimar discovery story began when Chalice Mining took a bold mineral exploration approach in an area that had previously received little attention from mining companies. Despite Western Australia's rich mining history, the geological potential of the Julimar region had remained largely unexplored until Chalice's strategic drilling program.

The first diamond drill hole at the Gonneville prospect returned extraordinary results, intersecting substantial high-grade PGE-nickel-copper-cobalt mineralization. This discovery hole immediately signaled the potential scale of the deposit, triggering one of the most successful mineral exploration stories in recent Australian history.

Unlike traditional discoveries that often follow established geological models, the Julimar find demonstrated that significant mineral deposits can still be uncovered in relatively accessible areas using innovative exploration techniques and geological reinterpretation.

Julimar's Impressive Resource Profile

Following extensive drilling campaigns, Chalice Mining has defined a remarkable mineral resource at the Julimar deposit. The Gonneville prospect contains an estimated 560 million tonnes at 0.54% nickel or approximately 1.7g/t palladium equivalent. This translates to:

• 17 million ounces of 3E (palladium, platinum, and gold combined)
• 960,000 tonnes of nickel
• 540,000 tonnes of copper
• 96,000 tonnes of cobalt

When converted to equivalent terms, this represents approximately 3 million tonnes of nickel equivalent or 30 million ounces of palladium equivalent. Notably, 55% of this resource falls within the Measured and Indicated categories, with the remainder classified as Inferred.

The deposit features multiple mineralized zones with varying metal concentrations, including both oxide and sulfide components. The sulfide mineralization exhibits excellent metallurgical characteristics, with initial testing indicating good recovery rates for the primary minerals of economic interest.

Strategic Location Advantage

The geographical positioning of the Julimar deposit represents one of its most compelling advantages. Located just 70km northeast of Perth, Julimar enjoys proximity to:

• Major transportation infrastructure
• Established power and water networks
• A skilled local workforce
• Processing and refining facilities
• Export terminals and shipping routes

Unlike many major mineral discoveries that occur in remote locations, Julimar's proximity to Perth—just one hour's drive away—provides significant logistical and operational advantages. This location eliminates the need for fly-in, fly-out (FIFO) arrangements, allowing workers to commute daily and reducing infrastructure costs substantially.

The deposit also benefits from being situated in Western Australia, a jurisdiction with well-established mining regulations, transparent permitting processes, and a history of supporting resource development while maintaining environmental standards.

How Does Julimar Support the Green Energy Transition?

• Regulatory Process: Environmental approvals and permitting still in progress

Securing this level of capital investment represents a substantial challenge, even for a deposit of Julimar's quality. The company will likely need to explore multiple financing options, including:

1. Strategic partnerships with end-users or processors
2. Government development funding or loan guarantees
3. Traditional equity and debt markets
4. Potential joint venture arrangements
5. Staged development approaches to reduce initial capital requirements

The extended timeline from discovery to production is typical for major mining projects but presents challenges in maintaining investor interest and adapting to changing market conditions over a multi-year development period.

Market and Commodity Price Volatility

The project economics are heavily influenced by commodity price fluctuations:

• Price Sensitivity: The original scoping study assumed palladium prices of US$2,000 per ounce, while current prices are approximately half that amount
• Battery Metals Downturn: Recent declines in nickel and other battery metal prices have impacted investor sentiment
• Offtake Uncertainty: Despite the resource's size and quality, no binding offtake agreements have been secured

This price volatility creates significant uncertainty in financial modeling and investment returns. Particularly challenging is the current palladium market, which has seen prices decline substantially from their 2022 peaks, impacting the projected economics of the Julimar operation.

The multi-commodity nature of the deposit provides some natural hedging against individual metal price fluctuations, but also creates complexity in marketing and offtake arrangements, as different buyers may be interested in different elements of the production profile.

Project Development Status

The project remains in relatively early stages of development:

• No Preliminary Feasibility Study (PFS) has been completed yet (expected by end of 2025)
