Osena – Gold & Copper
738 km²
K92 – Kainantu Gold Mine
Exploration
South Pacific’s Osena Project, covering 738 km² of strategic ground, is located southwest adjacent to the Au-Cu-producing K92 Project in the mineral-rich Kainantu District. A major NE trending structural corridor known for high-grade Au-Cu-Ag veins is interpreted to extend into Osena’s land holdings. Focus prospects include Ontenu, a large-scale cluster of five intrusive Copper-Gold porphyry, vein and skarn complex extending over 5 km x 3 km. Recent results from Ontenu Central confirm gold-bearing breccias and include a 79 m trench averaging 0.75 g/t Au, including 4 m at 4.52 g/t Au with a high up to 8.82 g/t Au. Historical rock samples targeted for follow-up include 73 g/t Au, 960 g/t Ag, 3.17% Cu & 10.6% Zn (in different locations). More than half of the project tenure remains unexplored.
738 km² land package adjacent to the Au-Cu-producing K92 Project in the Kainantu District, featuring a major NE structural corridor hosting high-grade Au-Cu-Ag veins
This corridor includes over 15 porphyry, skarn, and epithermal occurrences, with multiple mineralized NE structural zones extending across a 50×30 km district
Priority prospects include Ontenu and Tirokave, with numerous additional targets identified across a distance of more than 45 km
Osena hosts more than 15 Au-Cu porphyry, epithermal, breccia and skarn occurrences with numerous targets across a distance of more than 45 km. Ontenu and Tirokave prospects are characterized by large mineralization and alteration footprints with coincident geophysical and topographic anomalies in complex structural settings. Exploration program currently being prepped.
Ontenu represents a large-scale, multi-intrusive Copper-Gold porphyry, vein and skarn complex extending over 5 km x 3 km, with a cluster of five highly-prospective geophysical targets with correlating surface Cu-Au anomalies.
Ontenu Central: Classically zoned porphyry system with widespread propylitic to advanced argillic (with narrow structural zones of potassic alteration associated with hydrothermal breccias and bornite (copper sulphides)). This is suggestive that Ontenu is at the top of a preserved major porphyry system with a large Cu-Au porphyry target at depth (approximately 250 m below surface):
Ontenu Northeast: Visible gold identified in stream sampling from 1985, draining this topographic high that is also a coincident apparent conductivity-magnetic geophysical anomaly. Historic work by RGC identified phyllic and propylitic alteration proximal to this feature and completed limited soil sampling returning anomalous Au and Cu. They interpreted the area to be prospective for lode-gold type mineralization (they were pursuing bulk-style gold only). This is a top-priority prospect.
Strong evidence of potentially mineralized NE structural zones covers a broad 50×30 km district. The property hosts multiple, large Au-Cu mineralization and alteration anomalies (up to 6×3 km) associated with the intrusion of the Elandora Porphyry (a known mineralizing intrusive regionally).
