BHK MINING CORP. BHK Mining Corp. conducted a 33 hole auger drilling program to test for gold mineralization near surface on the company's 100% owned, 2,000 square kilometre, Ndjole Licence, in central Gabon. A total of 146 auger samples were submitted to ALS Chemex in Johannesburg South Africa for fire assay.
During the initial, completed auger drill program at the North East target, three lines of auger holes were drilled to intersect the projected surface expression of a high-grade gold intercept from core drilling completed by Silver Bull Resources Inc. This northeast gold mineralization also trends towards another gold intercept from 2011 core drilling (NDD0007 - 1m @7g/t). The northeast mineralization trend defines a walk-up drill target over 1 kilometre in strike length that will be drilled during the second half of 2015. Auger holes are drilled vertically using a manual auger machine and samples collected at 1 metre intervals.
The auger drill tubes are cleaned between samples however there is a possibility of contamination between samples as this is an open hole method. These auger samples are air dried, crushed and then split. The split sample, which weighs approximately 300 grams, is submitted to ALS Chemex Laboratory in Johannesburg for fire assay analysis.
Certified standards, blanks and field duplicates are inserted into the sample batches at a rate of 1 standard, 1 blank and 1 duplicate for every 30 samples. These quality control assays are inspected and reported on for each batch of assay results received. The auger samples were submitted for gold fire assay at ALS Chemex Johannesburg, which is an ISO9001: 2000 accredited laboratory for provision of assay and geochemical analytical services.
Crushing - >70% of sample passes 2mm screen; Pulverising - > 85% of ring pulverized sample passes 75 micron screen; and analysis method Au-AA23: 30g nominal sample weight by fire assay and AAS. Method Precision +/- 10%. Reporting Limits 0.005 -10ppm.
