Jameson Resources has released the results of its coke strength after reaction (CSR) tests for coal quality at the south block of its Crown Mountain metallurgical coal project in British Columbia.
The company had previously released CSR results for the north block of the project, which ranged between 73 – 76.
The results are from sole heated oven (SHO) testing. The first three CSR results received for south block have ranged from 67 – 74. The company confirmed that these results indicate the Crown Mountain product is expected to be a hard metallurgical coal.
Samples analysed were taken from (a) hole CM11-22-CH seam 10 blend, (b) hole CM11-22-CH seams 8, 9, and 10 blend, and (c) hole CM13-15-CM seam 10 blend. The CSRs are 68.7, 66.8, and 74.4, respectively.
CSR is one of the most important and widely accepted properties of metallurgical coal. In the Elk Valley, typical coal shipments run between 68 and 72 CSR. The Crown Mountain CSRs indicate a hard metallurgical coal similar to the high quality produces shipped from neighbouring mines. While further work (such as pilot oven testing) will be required to confirm these initial CSR results, Jameson Resources said that SHO CSRs are generally reliable and widely accepted as indicative of a coal’s metallurgical properties.
The company said it was “very pleased” with the CSR results and remains enthusiastic regarding the potential of the Crown Mountain project. The prefeasibility study continues to progress, with a completion date expected by June/July this year.
