Pan Global Resources Inc. (TSXV: PGZ | OTCQB: PGZFF) has announced successful results for preliminary metallurgical test work from the La Romana copper-tin-silver discovery at the company’s Escacena Project, Spain. The metallurgical test work reported was completed by Wardell Armstrong International (United Kingdom), under the coordination and management of SCYPI (Spain).
“The high copper recoveries and concentrate grades achieved at this early stage are highly encouraging. It is not just the recoveries and concentrate grade that makes these results very good, it’s the combination along with low deleterious metals and coarse primary grind size, particularly when compared to what we know of the other deposits in the area, and potential for lower final energy consumption. We are looking forward to the results from the ongoing tin metallurgy test programme and variability tests on the copper and tin mineralization from different parts of La Romana, including areas of higher-grade mineralization,” said Tim Moody, Pan Global’s president and CEO.
The metallurgical testing programme was conducted by Pan Global using representative core from the 2022 La Romana drilling campaign to establish copper recoveries and concentrate grades. The company has stated that whilst the metallurgical test work is ongoing, the results achieved for the first phase of testing demonstrate the potential for a conventional flotation process flowsheet capable of recovering copper into a saleable concentrate.
In its report, SCYPI commented: “As compared to the average of the Pyrite Belt deposits, La Romana mineral has shown lower energy requirements for crushing and grinding and better flotation process performance for copper (both concentrate grade and recoveries) using conventional circuits and chemical agents, anticipating moderate operating costs related to the process.” In addition: “Pending receipt of the detailed analysis of the concentrates, the low grade of deleterious elements (As, Sb, Bi, Hg, Cl and F) together with additional credits from Ag, will contribute to a higher NSR value.”
The test results to date indicate that a simple conventional flotation process flowsheet will be suitable for the La Romana copper mineralization. Follow-on work will include settling/dewatering tests and environmental characterization tests. A tin metallurgy programme has also commenced to determine processing and recovery options using representative samples from drill core in the areas of La Romana that reported higher grades of tin. A variability test work programme is also planned on samples from various parts of the deposit with varying copper and tin grades, including the higher-grade parts of the deposit.
Pan Global believes the results from the metallurgical test work further reinforce the positive attributes of the Escacena Project. Together with the ongoing test work, these results will form the basis for advancing the La Romana discovery towards a resource and future PEA.
The company has been operating three drill rigs in 2023 at the Escacena Project. The final hole is in progress on a planned 10-hole infill plus step out drill programme at the La Romana discovery.
Pan Global expects results for the first three drill holes at its Romana Deep target to be reported shortly and drilling at its Zarcita target is ongoing with additional results are anticipated over the coming weeks.
Pan Global has also reported that discussions are advancing with local land owners on access to potential near surface extensions of the La Romana mineralization along strike to the west and to the east, which remain untested.
