BLUE RIVER REPORTS DISCOVERY OF GOLD MINERALIZATION AND EXPANSION OF TRENCHING PROGRAM ON OKALLA WEST ZONE
Blue River Resources Ltd. is providing an exploration update from the Okalla West exploration prospect in Cambodia.
The Okalla West surface gold zone is within the 150-square-kilometre Banlung exploration licence in Cambodia. Work on the Banlung property is done under an agreement with Angkor Gold Corp, which is the operator.
As previously reported (see release dated Jan. 23, 2017) - exploration continues within the previously discovered 4 km2 surface gold anomaly at Okalla West. 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 15m 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 mineralization 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. Exploration this week 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 mineralization 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 mineralization. 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. Please see the location map that accompanies this release for details.
Assay results from trench and auger samples will be reported as they are received. The grab samples described above 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 mineralization hosted on the property.

PIT / TRENCH METHODOLOGY
Trenches consist of lines of pits laid across identified gold in soil anomalies in irregular east/west orientation. Individual pits are approximately 1m wide and 2m long, dug to the depth of the laterite. Pits are hand dug every 15 m centre. Each pit is sampled from the top to the bottom of the laterite for pan concentration. The pan concentration samples are a minimum of 15 kilograms. A second smaller sample is collected and will be sent for metallic screen analysis. In addition, the bedrock is sampled by an auger hole from the bottom of the pit. The last 50 centimetres of the auger sample will be sent for analysis. The auger holes test as deep as is possible into the weathered bedrock. The deepest so far has been 7.2 metres measured from the surface profile.
Angkor's QA/QC protocol requires calibration standards and blanks be inserted at a rate of 10 per 100. In addition, periodic checks are run on a selected spectrum of samples at ALS laboratories. All soil and rock samples are submitted to ALS Mineral-Australian Laboratory Services (Cambodia) Co. Ltd for preparation in Phnom Penh, and gold analyses are done by ALS by standard fire assay in their Vientiane laboratories. All other analyses are by ICP-ME and ICP22 in their Australian laboratories. Initial assays use their Au-ICP22 method of standard fire assay with an ICP-Atomic emission spectrometry finish on a 50gm aliquot, which has a detection range of 0.001 to 10 g/t. Check assays use the Au-AA26 method of standard fire assay with an ICP-Atomic absorption spectrometry finish again on a 50gm aliquot, which has a detection limit of 0.01 to 100 g/t. Metallic screen analysis, using their Au-SCR22 method of standard fire assay with an ICP-Atomic absorption spectrometry finish after screening to 75 microns use a 1kg nominal weight sample, with assay of the entire oversize fraction and duplicate assay on 50gm aliquots of the undersize fraction. This last method has been done at the recommendation of the laboratory to avoid over or under-estimating gold grades because coarse gold was suspected.
