Zacapa Resources (TSXV: ZACA | OTCQB: ZACAF | DE: BH0) has completed an inaugural drill campaign at its 100% owned Red Top Porphyry copper exploration project in the Superior Mining district, 8km northwest of Rio Tinto/BHP’s Resolution development project.
Initial drilling at the Red Top project has revealed an exciting new discovery of a quartz monzonite porphyry intrusive cut by copper-bearing veins occurring in association with low-temperate quartz-sericite-pyrite (QSP) alteration. This style of QSP alteration is consistent with alteration peripheral to the centre of a porphyry copper intrusive system and is typically low in overall copper grade. So, the company was encouraged by hole RT-21-001 which displayed copper-bearing veins in association with a distal alteration assemblage. The Resolution copper deposit, 8km to the southeast, displays similar copper-rich zones within its QSP alteration halo.
Based on this early success the planned 2-3 hole, 3,000m drill program was rapidly expanded to 6 holes and 5,000m. The final two holes RT-22-005 (920m) and RT-22-006 (817m) were completed in April and May respectively. Alongside this expanded drill program the company carried out additional staking, geologic mapping, hyperspectral remote sensing, and airborne magnetic and MT geophysical surveys to help vector in on the core of the intrusive system.
Porphyry style veins, predominantly with similar QSP alteration assemblages were encountered over significant thicknesses in each drill hole, with varying abundance of veins containing copper, lead, zinc, and molybdenum sulphide minerals. Assay results from RT-21-001 and RT-22-002 have been received and confirm the presence of elevated Cu, Pb, Zn, Mo, Au, and Ag within discrete vein sets, although none of the intercepts yet have intercepts that would be considered economically significant. The presence of copper-sulphides within the distal QSP alteration assemblage is encouraging in its similarity to the mineral system at Resolution. Assays from the remaining four drill holes are pending and the full incorporation of all the new data sets is in progress.
Adam Melnik commented, “The technical team has done an excellent job of rapidly expanding the scope at Red Top to fully evaluate the potential of this project and maximize our time with the available drill rig. We tested a 1.5 × 1.1 × 0.9 km area and encountered veining and alteration throughout and are looking forward to integrating the abundance of new data we have available and planning the next phase of work at Red Top. The team has already begun transitioning to focus on our upcoming drill program at our South Bullfrog project while we wait for final results and interpretation of the Red Top drill campaign.”
