Strongbow Exploration announced the discovery of high-grade copper-tin mineralization at its United Downs project.
Strongbow Exploration (TSXV:SBW) announced the discovery of high-grade copper-tin mineralization at its United Downs project. The asset is located in the UK, and the mineralization is between the historic United mine and Consolidated mines.
As quoted in the press release:
- Diamond drill hole GWDD-002 was drilled by Cornish Lithium to test the potential for lithium in brine at United Downs, within the historic Gwennap copper and tin mining district;
- Gwennap was the richest copper producing region in Cornwall (and the world) in the 18th and early 19th centuries, and at that time was referred to as “the richest square mile on earth”;
- GWDD-002 intersected semi-massive sulphide mineralisation between 90.60m and 105.29m downhole depth;
- Assays returned 14.69m grading 7.46% Cu, 1.19% Sn, and 0.15% Zn from 90.60m to 105.29m downhole length;
- Further drilling is required to confirm true width, as well as the strike and dip of the mineralised zone;
- Three individual sample intervals returned assays greater than 20% Cu – final results for these overlimit assays are pending, and will be reported when received;
- The semi-massive sulphide mineralisation is similar in style to that mined at Wheal Jane and Mount Wellington mines, located 1.5km along strike to the east; and
- Copper grades reflect recorded historical mine production from United Mines located approximately 200m to the south.
