"An investment in knowledge pays the best interest."



Blue River Resources Ltd. (BXR.V) has released results from a recent gravity survey conducted on the four-square-kilometre Okalla West surface gold zone, within the 150-square-kilometre Banlung exploration tenement in Cambodia in joint venture with Angkor Gold Corp.

The gravity survey results indicate a 4 km2 gravity high that directly coincides with the previously delineated 4 km2 surface gold zone. The high gravity results, combined with surface gold anomalism indicate the potential for a large, sub-surface, Intrusive Related Gold system (IRG) underneath the Okalla West prospect zone.

Drilling and Trenching Plans for Okalla West

The next phase of exploration on the Okalla West Gold zone will consist of trenching and drilling across 5 lines each of approximately 200 to 360 meters in length. The trenching program is designed to test the potential for the overburden to contain near-surface gold mineralization, as indicated from extensive termite mound sampling and augering. It will consist of drilling and pit excavation along the trenching lines.

The drilling program will consist of drilling 30 holes to 40 meters in depth, along the 5 trenching lines, for a total of 1200 meters.

"With the grade of the gold increasing with depth, ranging up to 2.45 g/t", this follow-up exploration program will test these large anomalies by drilling at least 40 meters below surface and trenching" states Jonathan Soper, P.Eng. Chairman of the Advisory Board for Blue River Resources. "The previous auger program, explored only a fraction (0.67 km2 ) of the 4 km2 surface gold anomaly area and did not reach the targeted depth of the contact between the overburden and bedrock". .

BETEC geophysical company ran four lines, totalling 30 line kilometres over the intrusive complex, as shown below.

Not surprisingly, the gravity profiles very closely mimic the magnetic profiles.

The study enabled a fair model of the probable geology to be created, in two dimensions, but with some confidence, as depicted below.

In the sections modelled above, the sedimentary rocks, which are mostly sandstones and siltstones are shown in yellow, with a specific gravity of 2.60, gabbro is dark blue, with a density of 2.82 t/m3 diorite is pale blue, with a SG of 2.72 and the ultramafic olivine pyroxenite is red with a SG of 3.08. Significantly, the gold index anomaly coincides with the gravity and aeromagnetic low, over the diorite intrusive.

A gravity low, complex structure and visible gold surface anomaly in the same overlapping area, within the Mafic Intrusive Complex, are all good indicators for the potential presence of a felsic, Intrusive Related Gold system (IRG), beneath the surface of the Okalla West prospect area.
