Pensana Rare Earths Plc (LSE: PRE, ASX: PM8) is pleased to announce a substantial upgrade to the Mineral Resource estimate for its Longonjo Project.
International mining industry consultants SRK Consulting has reported an upgraded Measured, Indicated and Inferred Mineral Resource estimate of:
313 million tonnes at 1.43% REO including 0.32% NdPr for 4,470,000 tonnes of REO including 990,000 tonnes of NdPr
*NdPr = neodymium+praseodymium oxide. REO = total rare earth oxides. A 0.1% NdPr cut is applied. Tables 4 to 7 summarise the estimate at a range of cut off grades, material types, resource categories and individual rare earth oxide grades.
The upgraded estimate:
· contains more than 2.3 times the previous estimate of the Measured and Indicated resources used in the Preliminary Feasibility Study1 (announced ASX: 15 November 2019).
· has increased the proportion of the resources reported in the Measured and Indicated categories from 31% to 68%;
· and has increased the overall contained NdPr by 35%;
At a 0.2% NdPr lower grade cut, the Measured and Indicated Mineral Resource estimate for the Weathered Zone is:
39.9 million tonnes at 2.38% REO including 0.52% NdPr for 948,000 tonnes of REO including 208,000 tonnes of NdPr
A 0.2% NdPr cut is applied. Weathered Zone Measured and Indicated categories only, and is contained within and is a subset of the Total Mineral Resource estimate.
----------------------------------------------
If you take 208,000 tonnes of NdPr at 27% conversion rate through as reserves and then recovered after final production equals 14 years at 4,000 tonnes of NdPr through Saltend processing. The COOLA inferred resources have yet to be converted to resources but were expected to add a further 7 years to give 21 years of mine life. The 27% figure is highly conservative on conversion rate which in theory could be as high as 54%. However, the price variation in the market place is volatile and could range between $50,000 a tonne to $200,000 a tonne. Some may choose a 40.5% conversion metric with a mid-point $125,000 per tonne. After that you would need to run models on margin rates like at 33%, 25% and 17% to give different profit profiles and then you could estimate on enterprise values and pay back on the construction debt which is listed on the company website.
