New Porphyry Mineralization With First Drill Hole At Red Top In Arizona

VANCOUVER - Zacapa Resources Ltd. announced that drill hole RT-21-001 has been completed to a depth of 1,042 meters at its 100% owned Red Top porphyry copper project in the Superior Mining District, Arizona. Drill hole RT-21-001 was designed to test for porphyry copper mineralization beneath a large (>3.5 kilometer by 1.5 kilometer) outcropping zone of quartz-sericite-pyrite alteration with a core of advanced argillic alteration (pyrophyllite-illite-sericite). RT-21-001 encountered hydrothermal alteration and veining from surface to end of hole at 1,042 meters, including numerous intervals containing visible sphalerite, galena, chalcopyrite, bornite, and locally molybdenite. Assays are expected in the coming weeks.

Porphyry style alteration and veining throughout RT-21-001 confirms the presence of a new copper and molybdenum bearing porphyry system in Arizona's Superior Mining District only 8 kilometers northwest of Rio Tinto/BHP's Resolution mine development project (1.8 Bt @ 1.5% Cu). The first diamond drill hole completed at the Red Top porphyry copper project to a depth of 1,042 meters, including visible copper minerals throughout most of the hole.  Second hole underway 500 meters to the east-southeast.

"The alteration and mineralization observed in RT-21-001 is consistent with the alteration footprint of a porphyry copper intrusive center and suggests that we have drilled the periphery of a new porphyry copper system," said, CEO & Director, Adam Melnik. "The presence of chalcopyrite and bornite in the distal porphyry copper environment indicates that the core of the system has potential for high-grade copper sulphide mineralization."

RT-21-001 encountered copper sulfide mineralization and previously unknown porphyritic intrusions that are not present at surface. The original planned depth for the hole was 800 meters, but it was continued to 1,042 meters, based on recurring copper mineralization in the drill core. The drill hole demonstrates that much of the hydrothermal system is hosted in favorable rock units (porphyry intrusions) and that the observed alteration (dominantly sericite and chlorite with variable pyrite), and vein styles (sericite ± chlorite ± quartz) are consistent with the periphery of a typical porphyry copper deposit footprint.
