On 1 December 2020, Allegiance Coal Limited announced a four year off-take contract with Mays to acquire 30,000 tonnes per month of Pratt seam coal increasing to 60,000 tonnes per month, to blend with New Elk's Blue seam coal at a ratio of ~53% Blue to ~47% Pratt. Following CSR tests undertaken on the Pratt, lower than expected results were received reducing the status and value of the Blue Pratt blend ­ the calculated CSR was 50 against a CSR test result of <40. Mays could not therefore deliver the CSR specification of 50 under the terms of the off-take contract. Allegiance and Mays have agreed to replace Pratt coal with NPA coal supplied by Yellowhammer Energy Solutions, LLC., a Mays related entity, on generally the same terms and conditions except the fixed price component increased by around 20% reflecting the significantly better coal quality, off-set in part by an increase in the bonus payment threshold from >USD 110 per tonne to >USD 115 per tonne. The Blue NPA blend is less complex at 50:50, and materially improves the quality of the blended product to the point where the blend is on the cusp of high vol A coking coal, likely to be priced as a tier two high vol A (due mostly to the CSR not being closer to or in excess of 60). Platts quotes for high vol A and B (FOB US East Coast) at the close of last week were USD 190/tonne and USD 167/tonne, respectively. Platts guideline specifications for high vol A and B are: HVA: ash 7.5%; vols 32.25%; sulphur 0.9%; and HVB: ash 8.0%; vols 36.00%; sulphur 1.0%.
