Richfield Ventures Corp. (TSX.V:RVC) has reported drill results for four diamond drill holes on the 100% owned portion of its Blackwater Gold Project approximately 100 km south of Vanderhoof, BC.
Drilling is focused on testing the continuity and size of the bulk tonnage gold system.
BW 87 is 163 metres southeast of the collar of BW 59 (361 metres of 1.25 g/t Au within 455 metres of 1.03 g/t Au - see NR May 6, 2010), 350 metres east of BW 68 (227 metres of 1.51 g/t Au including 66 metres of 3.65 g/t - see NR July 26, 2010) and 269 metres northwest of BW 74 (231.96 metres of 0.75 g/t Au - see NR Sept 2, 2010).
BW 85 was drilled 50 metres west of BW 87. BW 86 and BW 88 were drilled along the south edge of the Richfield Zone. BW 88 returned anomalous gold grades.
Mineralization is dominated by fine grained pyrite and sphalerite disseminated through variably hydrofractured and silicified lapilli tuff and andesite-dacite. Sections with the strongest silicification are generally more strongly mineralized than less silicified sections. Visible gold occurs in the most strongly mineralized part of BW 87 about 135 m deep. It forms anhedral, equant grains about a millimeter across in fracture fills and irregular veinlets.
Peter Bernier, President and CEO observed "These latest results support our interpretation that higher grade near-surface gold occurs in at least three broad zones of plus 1 g/t gold."
Richfield is well-funded and logistically prepared to carry on drilling with two rigs through the winter months. Holes will be targeted to further explore and delineate the bulk gold deposit which is developing at the Blackwater Gold Project. All four holes were drilled vertically.
Widths reported are drill widths; true widths are unknown. Assays are uncut, length-weighted average values.
Quality Assurance
Richfield has implemented a rigorous quality assurance/quality control program at the Blackwater property using best industry practice and supervised by Dirk Tempelman-Kluit. The program includes chain of custody of samples from drill to laboratory. Drill core is sawn in half at the property and for each sample half of the core from one metre intervals is placed in plastic bags and sealed. The remainder is retained in core boxes stored at the project camp.
A standard sample, a blank sample, or a duplicate sample is inserted into the sample stream every tenth sample. Five certified ore assay laboratory standards are used in the program, and are supplied by CDN Resource Laboratories Ltd., an independent laboratory located in Langley, BC. Samples including the blanks, standards and duplicates, are shipped by bonded courier to Eco Tech Stewart Group Laboratories in Kamloops, BC, an internationally recognized analytical services provider. Rejects selected at random are sent to Acme Labs of Vancouver, BC for check assays. In total 222 quality control samples (14.5 % of all 1534 samples) were analyzed. Richfield detected no significant QA/QC issues during review of the data.
