Trenching work by Angkor Gold Corp at the Okalla West exploration prospect in Cambodia has revealed visible gold. This discovery has prompted the company to expand the trenching program.
The Okalla West surface gold zone is within the company’s 150sqkm Banlung Exploration Licence. Work on this prospect is done under an agreement with Blue River Resources.
Exploration continues within the previously discovered 4sqkm surface gold anomaly. Interpretation of previous testing results suggests two structural fault systems with the possibility of multiple quartz veins. Grab samples from field mapping show evidence of a quartz vein system in the surrounding area.
New trenching at Okalla West, which consists of a series of pits dug on lines at 15 metre intervals, has exposed significantly larger pieces of the vein material under the laterite on Line 5. Visible gold has been observed in vein material found in Pit 6 on Line 5.
While the veining and mineralisation appears to be typical of the occurrence, the amount of visible gold seen confirms the nugget effect previously observed. Vein material with pyrite in silica boxwork was found in Pit 4.
Recent exploration on Pit 9 has discovered pyrite rich material coming out of auger samples.
These field observations confirm the presence of vein material that further assists in the understanding of the larger geological structure underlying the previously identified gold anomalies. The appearance of the gold and the abundance of the silica material suggest a close source and a large system.
“Finding visible gold is always exciting,” said Angkor senior geologist Dennis Ouellette. “Finding it at the bottom of a small trench in a field with no outcrop is especially exciting. The extension of Pit 6 will allow us to determine more about the character of the gold mineralisation and hopefully lead to the discovery of more veins within the alteration zone.”
Angkor is extending the size of Pit 6 to follow and map the vein material. Digging of new pits will continue eastward until the company no longer observes evidence of mineralisation.
Exploration will also likely expand to another short line to the south and some infill trenches between lines to the north. So far, 13 pits have been dug on Line 1, 12 on Line 2, 24 on Line 3, 24 on Line 4 and 17 pits on Line 5.
The grab samples have not been assayed because they were selected for detailed examination of the mineralogy, not for chemical analysis, and the company cautions that grab samples are selected samples and may not be representative of the mineralisation hosted on the property.
Under an agreement with Angkor, Blue River Resources has the right to participate initially in up to a 50% interest of the Banlung licence from Angkor after the completion of a total investment of US$3.5 million in exploration expenditures over a 4-year period.
Blue River may then exercise its option on an additional 20% interest of the Banlung tenement through the commission and completion of a bankable feasibility study on the property or portion thereof.
