SOMA REPORTS POSITIVE ORE SORTING RESULTS
Soma Gold Corp. has released positive results from a preliminary ore sorting study conducted on a bulk sample of mineralized material from the Cordero mine in Antioquia, Colombia. An evaluation of sensor-based sorting technology was carried out at the Steinert Latinoamericana Test Center in Pedro Leopoldo, Brazil, on a 1,200-kilogram bulk sample. The objective of the testwork was to achieve the highest possible metal upgrade by rejecting up to 50 per cent of gangue material.
A series of calibration samples, representing four grade bins, was scanned with four standard sensors. These data were used to inform the decision to utilize the 3-D laser and XRT sensors for the bulk sample test. The sample was crushed and screened to provide two size fractions for sorting. These samples were processed with a cascade method using 3-D laser and XRT sensors.
The data for the coarse fraction alone indicate up to 40-per-cent mass rejection and 94-per-cent metallurgical recovery while the data for the middling sample indicate up to 50-per-cent mass rejection and 86-per-cent metallurgical recovery. The fine material (fewer than 12 millimetres) was not processed through the sorter, but a representative sample was assayed to determine the metal contribution to the bulk sample.
Considering only the final sorted product from the coarse and middling samples, the 1,200-kilogram sample was reduced by 70 per cent to 570 kiograms, effectively increasing the grade by 275 per cent from 7.45 grams per tonne to 20.44 grams per tonne, while accounting for 90 per cent of the gold in the bulk sample. The results demonstrate that Cordero mine ore is amenable to sorting and that SBS technology can achieve desired gold-grade targets with high mass recovery, minimizing the amount of metal lost to the reject stream.
Mark Bren, Soma's vice-president, operations, stated: "We are extremely pleased with the results of the sorting test. Ore sorting has the potential to significantly impact our operation by allowing us to increase gold production without adding plant capacity. Of course, this is the first step, and we will study the results to optimize the metal recovery and rejection curves to find the proper operating scenario. The next step is to install a pilot plant to process ROM material at a commercial level, enabling us to adjust algorithm parameters to optimize the sorted product for plant feed. Installing this equipment at each of the El Bagre and El Limon mills could effectively double throughput and ounces produced, reducing reliance on either mill to maintain planned production levels."
