After its discovery, the size and shape of the Hapa target was defined by infill soil sampling on a 100m X 100m grid in the abnormal zone (Figure 2). To date, rock chip and channel samples along streams have assayed up to 1.29% copper and 0.33% molybdenum. Copper and molybdenum mineralization occurs as disseminations and bubbles in granodiorites, sets of porphyry-style quartz veins and sulphide-rich ribbon veins including pyrite, chalcopyrite, chalcocite, covellite and molybdenite (Figure 3). Native sulfur was also noted in the outcrop and a high sulfur anomaly in the soil coincides with copper, molybdenum and tungsten anomalies in this soil study data, all indicative of porphyry mineralization. The copper-molybdenum anomaly forms an irregular “bull’s eye” with a diameter of approximately 1000 m when profiled at 400 ppm copper and 20 ppm molybdenum. Host rocks are hydrothermally altered and locally faulted granodiorite, granodiorite porphyry and diorite magmas. Zamora batholith. Late and localized porphyry dykes cut intrusive rocks.

Geological mapping along the streams at Hapa has delineated an elliptical zone of sericite-quartz (phyllic) alteration, approximately 1 km in diameter, which coincides with soil anomalies in copper and molybdenum. Near the center of the phyllic zone is a narrow window of potassium alteration (potassium feldspar (Figures 4 and 5). Outside the phyllic zone, the hydrothermal alteration becomes propylitic, characterized by a chlorite-epidote mineral assemblage. carbonate-magnetite This concentric zonation of hydrothermal alteration minerals is typical of copper porphyry deposits.

Luminex interprets that a porphyry copper intrusion is located below the Hapa geochemically anomalous zone, indicating good preservation of the phyllic and underlying potassium alteration zones and the potential for secondary copper enrichment. The target area is centered on a rugged hill, possibly the product of differential uplift between two formative faults which facilitated the establishment of the porphyry system (see Figure 5).
