History
Renascor grew from a uranium explorer into a graphite developer, funding Siviour through repeated share raisings and holding about A$94m cash by mid-2026 while awaiting a final investment decision.
2010-2012: A uranium explorer lists
The company, then called Renaissance Uranium, listed on the ASX in December 2010 after an $8.0 million IPO of shares at 20 cents. It held eight uranium projects in South Australia and the Northern Territory. Its first drilling, at Pirie Basin in 2011, found thick sands of the kind that suit uranium recovery, but no discovery. A rotary hole at Glensea returned 12 metres at 0.42% copper, and gold drilling at Cutana in 2012 gave modest results, with two of five targets finding nothing significant. Gairdner, a test described as the "company maker", found limited sulphides in its magnetic targets in November 2012. In February 2012 chairman David Macfarlane retired and Stephen Bizzell took over.
2013-2015: Copper at Eastern Eyre, then setbacks
After a long wait for Defence Department access, drilling at Eastern Eyre in 2013 found a copper-cobalt-silver zone at 1050 East, with 44 metres at 0.61% copper in one hole and 13 metres at 1.45% in another. The company renamed itself Renascor Resources in December 2013 to reflect a multi-commodity focus. Money was tight: it raised about $1.08 million at $0.05 in 2014, and shallow follow-up holes found only low-grade copper that management said was not economic. Extension Tank drilling in 2015 was downgraded after finding only low-level sulphides. Renascor raised $1.5 million at $0.02 and sold four Olary tenements for $250,000. Shares on issue rose from 136.9 million at the end of 2014 to 216.7 million a year later.
2015-2017: The pivot to graphite
In late 2015 Renascor bought the Munglinup graphite project and took an option on Eyre Peninsula Minerals, which held the option over the Arno graphite project. Drilling at Siviour in early 2016 hit shallow graphite, and a maiden resource of 16.8 million tonnes at 7.4% graphite followed in March 2016. Further drilling lifted it to 60.8 million tonnes in October 2016 and 80.6 million tonnes in March 2017. Funding came in small, cheap raisings, including $1.1 million at $0.015, options exercised for about $1.9 million, and about $3 million at $0.017 in 2017. Renascor took full ownership of Eyre Peninsula Minerals by issuing about 42 million shares and 15 million options. Richard Keevers became chairman from January 2017. A scoping study in May 2017 showed an after-tax NPV10 of A$551 million. Shares on issue reached 667 million by the end of 2017.
2018-2020: Studies, Ausmin and thin cash
A prefeasibility study in March 2018 gave a maiden Ore Reserve. Renascor raised $6.5 million at 2.7 cents and later bought Ausmin, the owner of Siviour, for about 187.6 million shares. It also signed a partnership with Royal IHC and was granted the Siviour mining lease in April 2019. The definitive feasibility study in November 2019 showed a post-tax NPV10 of A$388 million, well below the earlier spherical graphite study because prices were cut. Cash ran low, and the company raised $1.4 million at 1.1 cents in December 2019 and added a share purchase plan. The auditor flagged a going-concern uncertainty in March 2020. In 2020 Renascor engaged an adviser for debt financing, received support letters from Export Finance Australia and Atradius, and raised $3.6 million at 1.1 cents. It signed its first spherical graphite MOU, with Minguang, and a Rio Tinto farm-in on Marree.
2021-2022: Offtake MOUs and a funded balance sheet
MOUs followed with Zeto, Hanwa and POSCO, though none was binding. Renascor raised about $15 million at $0.08 in April 2021 and $65 million at $0.27 in April 2022. Export Finance Australia conditionally approved a A$185 million loan in February 2022. The Siviour resource was upgraded in August 2022. South Australia approved the mining program in November 2022, and a A$70 million placement at $0.275 followed in December, bringing pro-forma cash to A$140 million. Shares on issue grew from 1.88 billion at the end of 2021 to 2.52 billion at the end of 2022.
2023-2026: Optimised study and demonstration plant
The optimised study of August 2023 showed a post-tax NPV10 of A$1.5 billion, with upstream start-up capital of A$214.5 million. The Ore Reserve rose to 61.8 million tonnes and the Mineral Resource to 123.6 million tonnes. The company bought the freehold land over the deposit, signed an Indigenous Land Use Agreement with the Barngarla in 2024, and won a $5 million grant towards a $10 million demonstration plant. Contractor submissions in March 2025 raised the plant capital estimate by 4.7%. Bolivar received provisional planning approval in June 2025, and the bulk sample gave concentrate at 96.8% carbon. The demonstration plant began processing graphite with reagents in June 2026 and was opened in July. As of July 2026, Renascor had about A$94 million cash, no debt and about 2,541 million shares. The Export Finance Australia loan was still awaiting due diligence and documentation, no binding offtake had been signed, and no final investment decision had been announced.
