Very happy to read today’s RNS having been disappointed by ARCM results this morning . Appears Mr.Colin Bird knows the area better than most . Following taken from today’s RNS .
In July 2019 the Company undertook a preliminary confirmatory sampling programme along three hand-dug trenches across the tailings dumps. Two trenches were opened within the main tailings facility, while the third was within the swamp area, for a total of 420m. Trench depths ranged from 1.0m to 3.5m. 93 samples were collected, approximately every 5m along the trenches, by sampling vertical channels from top to bottom at each location. The sampling was planned to represent average sample values over a period of time during the historic mining operation. Sample weight was generally 2-3kg.
All samples were submitted for analysis to the SGS Kalulushi geochemical laboratory in Zambia. The laboratory is accredited to ISO/IEC 17025 standard for copper analysis.
Analytical results received for copper and silver yielded an average grade of 1.03% Cu, 4.44ppm Ag for all samples, with copper values ranging from 0.59% to 2.48%. Average grades were consistent through all three trenches although higher grade zones were delineated within each trench. Encouragingly, results overall support the copper grades reported in the 2013 resource estimate.
