Dorex Completes Sampling & Soil Grids - Strawberry Flats Gold Project
Vancouver, B.C. - - - Dorex Minerals Inc. (“Dorex” or the “Company”) has completed the Phase I rock, silt and soil geochemical sampling program on the Strawberry Flats Gold Project, Southern British Columbia, approximately 20 kilometers northwest of the historic Rossland Mining Camp.
Over 1,200 soil samples, 28 rock samples and eight (8) silt samples were collected by Dorex employees and contractors during the 10 day, on-the-ground program in late summer 2010. The Phase I exploration program was designed to confirm, infill and expand the historic gold-in-soil geochemical anomalies reported by previous workers as well as to ground truth the surface and underground workings on the Strawberry Flats Gold Property.
The bulk of the Phase I program consisted of a large geochemical grid covering an area of approximately 1.8 km by 1 km with 50 m spaced lines sampled on 25 m to 50 m centres. This grid was focused on expanding the historic geochemical grids to the North towards Astral Mining Corp’s contiguous Jumping Josephine Project. In addition, one detailed geochemical grid was established near the known anomalies on the Strawberry Flats Gold Project during this program. This detailed grid covered an area of approximately 120 m by 140 m with 20 m spaced lines and sampled on 10 m centre.
All collected samples were shipped to ACME Analytical Laboratories in Vancouver, B.C. where they were sent for analysis by Group 1EX ICP-MS for 41 elements and a 30 gram Fire Assay Finish (Group 3B01) on all samples.
Assay results are expected to be received shortly, and once compiled, these results will be used to define and prioritize targets for a Phase II follow-up mechanized trenching program planned for later this fall. Phase II will also concentrate on additional sampling from the historic anomalies as well as any newly generated geochemical anomalies from the Phase I program.
The Company’s 2010 exploration programs are primarily designed towards delineation of future drill targets for a Phase III diamond drilling program by confirming and expanding on the historical work from the Property including a trenching program completed by Cameco in 1989-1990.
The 1989-1990 programs were conducted to follow up on a potential bedrock source of gold-in-soil anomalies within the Strawberry Flats Gold Project. Cameco's “Trench No. 5” averaged 7.04 g/t Au (from continuous one-metre-long chip samples) over its 12 metre length and exposed a 7 metre wide fault zone with heavily silicified and pyrite chalcopyrite-galena-sphalerite-iron carbonate veined sections, with the a single 2 metre section reported to average 39.16 g/t Au and 6.55 g/t Ag.
Cameco's report indicated that the seven-metre-wide, west-northwest-trending mineralized structure exposed in Trench No. 5 is of sufficient grade to warrant follow-up along strike in both directions and at depth.
The Strawberry Flats Gold Project adjoins the Jumping Josephine gold project owned by Astral Mining Corp. and Kootenay Gold Inc. Drilling results from Astral on the Jumping Josephine main zone have included 10 metres of 9.95 g/t Au and 8 metres of 8.31 g/t gold.
