The funding package included a A$5m ($3.9m) placement, under which RCF would subscribe for 16.67 million shares in Vimy, at a price of 30 cents each.
An additional 1.5 million shares would also be issued in satisfaction of the up-front fee related with the overall funding package being offered.
RCF had also offered, in principle, a further A$25m ($19.7m) in funding to Vimy, comprising A$10m ($7.8m) in cash in exchange for a 1.15% royalty on all revenue produced from the Mulga Rock project, and a A$15m ($11.8m) unsecured bridge loan, with a March 2017 repayment date.
Vimy CEO and managing director Mike Young said: "We are very happy to have RCF’s support for the Mulga Rock Uranium Project. The recently released Scoping Study confirmed our belief that we have one of Australia’s best undeveloped uranium projects, viable at today’s long term pricing.
"RCF’s funding package will provide the funds we need to complete our studies and secure project financing for the MRUP."
A scoping study estimated that the project will generate average yearly earnings before interest, taxes, depreciation and amortisation of A$161m ($126m), at a uranium price of $75/lb uranium oxide.
It will have a pretax net present value of A$764m ($602m) and an internal rate of return of 39%.
