Test pit exploration by Angkor Gold Corp at the Okalla West project in Cambodia has revealed a north trending gold anomaly at least 320 metres in length and 45 metres in width. Okalla West is within the company’s Banlung licence in Ratanakiri province.
Ongoing exploration in this area is being conducted by Angkor in cooperation with Blue River Resources.
The test pit program began in January. Near-surface samples were analysed using a screened metallic process.
The anomaly occupies the southern lobe of the larger 4sqkm surface gold anomaly and sits on top of clay-weathered bedrock. The gold anomaly is located over diorite intruding gabbro.
Assay of vein material found in and under the deeply weathered surface layer returned values from 0.18 to 11.5 g/t gold.
The program involved the excavation of pits one metre by two metres. The pits were dug through to the bottom of the deeply weathered surface layer. Samples were collected for pan concentration testing and for metallic screen analysis. An auger hole was drilled from the bottom of each pit as deeply as possible and was designed to identify the underlying geology and sample the bedrock.
Two 100kg near-surface samples from new pits dug on lines 2 and 5 were collected. The samples were pan concentrated and have been sent to Canada for testing to determine the potential for bulk sampling and test processing. Near-surface samples analysed using a screened metallic process returned values from 0.15 g/t to 1.16 g/t.
Quartz vein material collected from the pits near or within the north trending anomaly returned highly anomalous results for gold. The vein material displays at least three phases of quartz mineralisation.
The first phase is massive white quartz and returned 0.18 g/t. The second phase consists of white and grey quartz breccia with abundant pyrite and returned 2.32 g/t. The third phase consisted of grey microcrystalline quartz in breccia with abundant pyrite. It returned 11.5 g/t.
The multiple phases of quartz and sulphide brecciation and deposition with visible gold indicates a typical structurally controlled ‘crack and seal’ system of gold mineralisation.
“The trenching results from Okalla West show good results on surface reflecting a bedrock hosted system just below,” said Angkor Gold CEO Mike Weeks. “We are excited to continue our exploration on this prospect.”
