Updates
28/08/2025: Cyprium Metals Limited has raised $80m of equity funding through the combination of a $74m placement and a $6m rights issue.
Company Overview
Cyprium Metals Limited (ASX: CYM) is an Australian copper mining and development company focused on restarting the Nifty Copper Mine in Western Australia. Cyprium’s flagship Nifty Copper Complex was historically a copper producer and hosts a remaining resource of over 1 million tonnes of contained copper. In addition to Nifty, the company controls the Maroochydore copper deposit and extensive exploration tenements in the Paterson Province, as well as the Cue Copper-Gold Project in the Murchison region of WA. The company has publicly stated an objective to become a mid-tier copper producer in Australia.
History and Corporate Development
Cyprium Metals underwent a corporate transformation in 2021 by acquiring a portfolio of copper assets from Metals X Limited for A$60 million. This February 2021 transaction included the Nifty Copper Mine (a brownfield operation on care-and-maintenance since late 2019) along with the Maroochydore Copper Project and related exploration tenements in the Paterson region. The Nifty mine had been in operation from 1993 until its 2019 shutdown, producing over 700,000 tonnes of copper metal during that period. Prior to this, Cyprium Metals was known as Arc Exploration Limited until a name change in 2019, marking the company’s shift in focus toward copper and base metals.
After acquiring Nifty and Maroochydore, Cyprium’s strategy pivoted to restarting copper production at Nifty. In mid-2023, new leadership joined, including Matt Fifield (appointed to the board and later Executive Chairman), and Cyprium raised A$31.6 million in capital by September 2023 to bolster its balance sheet. Fifield outlined a goal for the turnaround, stating that the Company is aiming to grow into a mid-tier ASX copper company with scalable assets in the Paterson and Murchison provinces.
Cyprium’s share price had fallen around 96% from its 2021 highs (above $0.30 in May 2021 to under $0.02 by early 2024). With a different management team and additional funding, Cyprium relisted on the ASX in June 2023 and continued to focus on delivering a restart at Nifty.
Nifty Copper Complex – Flagship Project
The Nifty Copper Mine (often referred to as the Nifty Copper Complex) is the centerpiece of Cyprium’s asset base. It is located on the western edge of the Great Sandy Desert in the Paterson/Pilbara region of WA, approximately 350 km southeast of Port Hedland. Nifty was historically developed as an open-pit mine (with a later underground phase) that produced copper from both oxide ore (via heap leaching and SX-EW cathode production) and sulphide ore (via flotation concentrate). The mine has existing infrastructure already in place, including an existing solvent extraction and electrowinning (SX-EW) plant and other facilities from its prior operations. Because Nifty is a brownfield site with a long operating history, the Company believes a re-start of operations would benefit from historical invested capital, a large on-site dataset, established camp and airstrip, and current environmental and mining permits that remain in force. The Company considers these advantages to be key to its redevelopment plans, which leverages existing site infrastructure and permits as typical of a brownfield operation.
Resource and Reserve
As of the latest estimates, Nifty contains a JORC Mineral Resource of approximately 1.04 million tonnes of contained copper in situ (inclusive of oxide and sulphide material). In November 2024, Cyprium released a Prefeasibility Study (PFS) for the Nifty restart, which for the first time defined an Ore Reserve of 797,000 tonnes of contained copper metal to be mined. This reserve underpins a potential 17-year mine life, with life-of-mine production projected at around 718,000 tonnes of copper payable. The November 2024 PFS reported an average ~37,000 tpa of copper over the first 10 years, based on the study’s assumptions (see ASX releases for details). Nifty’s remaining resources are considered to be largely in sulphide ore below and adjacent to the historic open pit, in addition to a mineral inventory of ~91,000 tonnes of copper already contained in the existing heap-leach pads on site.
Restart Development Plan
Cyprium’s redevelopment plan for Nifty involves a two-stage approach, tackling both the existing oxide dumps and the deeper sulphide resource:
Stage 1 – Heap Leach & SX-EW: The Company considers the reprocessing of the old heap leach pads to produce copper cathode by SX-EW to be the quickest, low-cost opportunity for early production. The PFS confirms the viability of retreating the heaps (Pads 1–6) to generate cathode, with an estimated capital cost of about US$30 million (plus contingency, ~US$46 million total including working capital) for refurbishing the SX-EW plant and associated infrastructure. This small-scale restart (targeting ~5,000 tonnes per annum of copper cathode initially) would capitalise on material already mined and leached, providing near-term cash flow while larger plans are finalised.
Stage 2 – Open Pit & Concentrator: In tandem, the company is planning an open-pit mine development to exploit Nifty’s sulphide copper resource. The 2024 PFS outlines refurbishing and expanding the previous concentrator plant on site and constructing a new open-pit operation. The estimated pre-production capital cost for the full concentrator and mine development is ~US$239 million (including plant refurbishment, new mining fleet, and infrastructure upgrades). The Company's envisioned plant would produce a copper concentrate (containing copper metal in sulphide form) for sale to smelters. The PFS stated a Net Present Value (NPV) of US$1.13 billion (pre-tax, 8% discount rate) and an Internal Rate of Return (IRR) of 28.9% pre-tax (23.6% post-tax). The PFS outlines a combined approach of reprocessing existing heaps (Stage 1) and developing an open-pit with concentrator (Stage 2).

Strategic Partnerships and Funding
To execute the Nifty restart, Cyprium brought on strategic partners and secured interim funding. In July 2024, the company announced a partnership with global commodities group Glencore, focused on supporting the restart of Nifty. Under this alliance, Glencore will purchase Nifty’s copper output under offtake arrangements to purchase copper production. In addition, Cyprium closed a A$40 million senior secured loan facility with Glencore in September 2024 as part of the deal. This funding is being used to advance Nifty’s early works, ongoing feasibility studies, and general corporate needs related to the project. The Glencore partnership also encompasses technical collaboration (e.g., leveraging Glencore’s smelting and processing expertise) and inputs like sulphuric acid supply for the SX-EW circuit. The Company believes Glencore's involvement supports the project's potential for development.
In early 2025, Cyprium signed an Early Contractor Involvement (ECI) agreement with Macmahon Holdings Ltd, a leading mining services contractor. Under this strategic alliance, Macmahon is taking the lead role in completing the bankable feasibility study (BFS) for Nifty’s redevelopment and is working closely with Cyprium on project planning. The ECI contract grants Macmahon an exclusive period to advance the feasibility and to negotiate a life-of-mine mining services contract for the future operation. Macmahon’s engineers and specialists are embedded in the study phase as they are contributing mine design, scheduling and cost estimation work, and are also tasked with identifying opportunities to accelerate first copper production using the existing infrastructure on site. According to Cyprium, Macmahon’s involvement brings real-world mining experience to the Nifty feasibility process, which the Company states is intended to support project execution.
With the PFS completed and partnerships in place, Cyprium’s immediate focus is securing the full project financing and final approvals from its Board to commence the Nifty restart. The company has also indicated in the past that it may consider selling up to a 30% interest in the Nifty project to a strategic investor or joint-venture partner to help fund development. Overall, Cyprium is targeting first production by 2026 and a ramp-up thereafter, which if successful, would mark the return of the Nifty mine as an Australian copper producer.
Maroochydore Copper Project
The Maroochydore Copper Project is located ~85 km southeast of Nifty in the Paterson region and represents Cyprium’s second major copper asset. Maroochydore is an undeveloped sediment-hosted copper deposit discovered in 1984 by Exxon (Esso) and delineated through multiple exploration campaigns over the decades. Cyprium acquired 100% of Maroochydore in March 2021 as part of the same Metals X deal that included Nifty.
Maroochydore hosts a substantial Mineral Resource defined in 2025: 370.8 million tonnes @ 0.43% Cu (Inferred category), containing approximately 1,595,000 tonnes of copper metal. The deposit also carries cobalt credits with the resource averaging ~227 ppm Co, for roughly 84,000 tonnes of contained cobalt in situ. The copper is predominantly in primary sulphide mineralisation at relatively shallow depths, with oxide and transitional zones near surface. Drilling to date indicates the orebody remains open along strike and at depth, which the Company suggests may have the potential to further grow the resource with additional exploration.
Currently, Maroochydore is at an advanced exploration and study stage. Cyprium’s has stated that it could undertake further infill and extensional drilling, as well as detailed metallurgical testwork, to better understand the deposit and optimise a processing flowsheet. By generating new core samples and conducting modern testwork, Cyprium aims to determine the best treatment route (e.g., conventional flotation to produce a concentrate vs. heap leaching for oxide portions, etc.). Given its scale, The Company believes Maroochydore could in the future become a standalone project or a satellite operation supplying feed to a Nifty-area processing hub. However, the Company has stated that development is not expected until Nifty is successfully restarted, as the Company considers Maroochydore to be a longer-term growth opportunity. Cyprium has stated that “refreshed views” on Maroochydore will be formulated after Nifty’s ramp-up, and that this project is not a high priority in the immediate term while the company’s resources are concentrated on Nifty.
Paterson Exploration Project
The Paterson Exploration Project is a package of exploration-stage tenements surrounding Nifty and Maroochydore, covering roughly 1,938 km² of the Paterson Province in WA. This district is considered by the Company to be prospective for copper and gold, hosting world-class deposits such as the giant Telfer gold-copper mine. Cyprium’s Paterson tenements were originally part of the 2021 Metals X acquisition and subsequently became subject to a farm-in joint venture with IGO Limited (ASX: IGO) in late 2020. Under that JV, IGO could earn up to 70% by spending $32 million on exploration over ~6.5 years. IGO invested heavily in exploration from 2020 through early 2025, with approximately A$24 million spent, including extensive geophysical surveys and over 36,000 metres of drilling targeting new copper discoveries. This work generated an extensive geological dataset and identified multiple targets within the Paterson ground, which the Company considers to be complementary to the known deposits at Nifty and Maroochydore.
In April 2025, IGO elected to withdraw from the joint venture, choosing not to proceed to the earn-in stage. As a result, 100% ownership of the Paterson Exploration Project reverted back to Cyprium Metals (effective 30 April 2025) with IGO retaining no interest. This development gave Cyprium full strategic control over the asset, which had been improved following several years of IGO’s exploration data. Cyprium management noted that they are incorporating the new data into a strategic review to prioritise targets for follow-up. Among the targets identified by IGO were various geochemical and geophysical anomalies, including prospects in the vicinity of the Nifty mine as well as more grassroots targets elsewhere on the tenure.
The Paterson exploration package includes multiple granted mining leases and exploration licences – in fact, it encompasses the mining leases for both Nifty and Maroochydore themselves, plus surrounding exploration licences. With the entire district now under one owner, Cyprium believes it has the potential flexibility to explore and develop the region holistically. The Company believes that any new discovery in this area could potentially leverage Nifty’s infrastructure in the future.
Cue (Murchison) Copper-Gold Project
Outside of the Paterson region, Cyprium also holds an interest in the Cue Copper-Gold Project in the Murchison district of Western Australia. The Cue project is an 80:20 joint venture between Cyprium (80% owner and operator) and Ramelius Resources (20%), covering approximately 118 km² of tenure near the town of Cue. This ground lies within a historic copper and gold mining area and includes the Hollandaire copper-gold deposit discovered in the 2010s. Hollandaire has an established Mineral Resource of about 2.8 million tonnes @ 1.9% Cu, 0.32 g/t Au, and 6.4 g/t Ag, containing roughly 53,000 tonnes of copper along with gold and silver credits.
Cyprium initially acquired its interest in Cue (including Hollandaire and nearby prospects like Nanadie Well) prior to the Metals X deal, and these Murchison assets were part of the company’s early copper exploration portfolio. In March 2025, Cyprium announced a proposed sale of the Cue Project to private company Q Resources Pty Ltd as part of a strategy to monetise non-core assets. However, a month later – after Cyprium regained the Paterson exploration ground from IGO – the company cancelled the Cue divestment by mutual agreement with the buyer. Management cited that with 100% of Paterson back in hand, they needed to re-evaluate the strategy for “non-core greenfield exploration assets,” and decided to retain Cue at least until that strategic review is completed.
At present, the Cue Copper-Gold Project is not a development priority for Cyprium, given the focus on Nifty. The company has acknowledged that its Murchison projects (including Cue and Nanadie Well) will likely be revisited once Nifty is in production and generating cash flow.
Corporate Strategy
Having consolidated a suite of copper assets, Cyprium Metals’ core strategy is to restart copper production at Nifty as a potential springboard for further growth. The successful execution of the Nifty restart by 2025–2026 is important for the Company's stated plans, as it would transition Cyprium from an explorer into a producer. The next steps involve completing the Bankable Feasibility Study (BFS) (expected in 2025) and arranging the project financing needed to cover the estimated capital expenditure.
If Nifty’s development proceeds as planned, first copper cathode from the heap-leach reprocessing could potentially be produced during the early ramp-up (targeting late 2025 or 2026), followed by first copper concentrate in 2026 after the concentrator commissioning. The Company holds key operating permits as disclosed in ASX announcements. Additional approvals, if required, will be sought in accordance with applicable regulations.
In terms of longer-term growth, management has emphasised that Maroochydore and the Murchison (Cue) project, while sizeable resources, will be advanced in the future only after Nifty is fully developed and generating stable cash flow (if successful). The Company has indicated that discoveries in the district may be evaluated for potential integration with existing infrastructure, subject to studies and approvals.
In summary, public disclosures indicate the Company’s current focus is progressing the Nifty restart in line with its published studies and plans. Readers should refer to ASX announcements for assumptions and risks. Development and other risks still remain (typical of any mining development). If Cyprium can deliver on Nifty, it would mark a significant milestone, not just for the company, but also for the Australian copper sector, as Nifty would resume its role as an important domestic source of copper metal.
