The West Perth-based company produced a pre-feasibility study (PFS) for the project in September 2018, finding it could produce a pre-tax US$1.4 billion free cash flow if it opted for a 9.5 million tonnes per annum throughput model.
Cardinal’s DFS is being funded through a US$25 million facility provided by globally-renowned resource investment outfit Sprott through Sprott Private Resource Lending.
Cardinal’s study demonstrated Namdini contained 4.76 million gold ounces from a maiden probable ore reserve estimate of 129.6 million tonnes at 1.14 g/t gold with a 0.5 g/t cut-off.
Speaking at the time, Cardinal managing director & CEO Archie Koimtsidis said the company had a compelling business case to move into the DFS phase for the throughput processing facility based on the optimum return on capital employed (ROCE).
He said: “The [definitive] feasibility study is fully-funded and will form the basis for the development of our Namdini project in Ghana with completion anticipated in Q3, 2019.
“The PFS study confirms the Namdini project as one of Ghana’s and Africa’s most promising undeveloped, large gold assets.
“The financial modelling of the project shows it to be technically sound and financially viable.”
The PFS used a US$1,105 an ounce gold price to provide a life-of-mine optimised pit converting 73% of the 6.5 million ounces of indicated mineral resource to probable reserves.
It estimated an 86% metallurgical recovery for the starter pit and 84% for the life-of-mine with ongoing optimisation test work.
A 38% post-tax internal rate of return (IRR) was generated through a US$1,250 gold price financial model.
The spot gold price was US$1,289.49 an ounce on Tuesday, January 15, 2019.
All-in sustaining costs (AISC) of US$599 per ounce were determined for the first 2.5 years, inclusive of a 1.8-year payback period.
The capital development cost for the 9.5 million tonne per annum throughput plant was US$414 million, down from US$426 million.
Ndongo East offers upside for Namdini
Drill results released since the Namdini PFS was published have continued to confirm the significance of a Ndongo East discovery, 24 kilometres south of Namdini.
Positive results reported in November 2018 included a 9-metre intersection grading 23.3 g/t from an initial 450-metre strike length of strong, shallow gold mineralisation which is open along strike and at depth.
Ndongo East has the potential to add further high‐grade gold ounces to Namdini’s maiden probable ore reserve of 4.76 million ounces.
Key figures sit on board
Cardinal MD Koimtsidis has been joined on the board of directors by a number of new faces.

The Centamin plant had a similar flowsheet to Namdini’s proposed flowsheet.
Schultz was a resident of Ghana for six years.
Four months ago, Ken Thomas & Associates Inc project development and metallurgy president Dr Kenneth G Thomas joined the board as non-executive director.

MD Archie Koimtsidis has more than 20 years' experience in gold exploration, discovery, production, and refining in West Africa and South America.
Koimtsidis has been instrumental in acquiring Ghanaian projects for Cardinal.
The MD has a strong understanding of West African and Ghanaian resource projects and was deputy country manager of Ghana for PMI Gold Limited before joining Cardinal.
