Rokmaster Resources Corp. [RKR-TSXV; RKMSF-OTC; 1RR-FSE] reported assay results of diamond drill holes RR21-34 to RR21-40 and wedge drill holes RR21-28a and RR21-28b. The results once again conclusively demonstrate the strong lateral and vertical continuity of gold-enriched massive sulphides in the Revel Ridge Main zone (RRMZ) and silver-zinc mineralization hosted within the Revel Ridge Yellowjacket zone (RRYZ) and related mineralized zones. The 100%-optioned Revel Ridge Project is located in southeastern British Columbia.
Results show a potential onset of mineralogical zonation, with the development of strong gold mineralization effectively occurring in the absence of arsenical sulphide phases within the Revel Ridge hydrothermal and structural system, suggested by drill hole DDH RR21-40.
Higher-grade mineralized zones are forming strongly consistent, predictable mineralized shapes or solids at production stope scale (validated by the use of controlled drilling practices and wedged drill holes).
A third mineralized silver-zinc-rich sulphide zone is developing in the southeastern deposit area between the RRMZ and Revel Ridge Footwall zone (RRFZ). This mineralized solid is currently identified as the Revel Ridge 28 zone (RR28Z). In the RR28Z, silver-zinc mineralization may occupy much of the interval between the RRMZ and RRFZ, which effectively merges the two zones and produces a thick, precious-metal-enhanced sulphide intersection.
Significant gold intersections have also been obtained from the RRFZ zone, which are typically cored 20 to 30 metres below the RRMZ.
There was significant expansion of known RRYZ silver-zinc mineralization. Drill hole RR21-28a returned 3.08 metres of 7.19 g/t gold equivalent (AuEq) or 545.38 g/t silver equivalent (Ag-Eq). Hole RR21-28b returned 4.85 metres of 4.95 g/t AuEq or 375.29 g/t AgEq.
These intersections are followed by significant silver-zinc mineralization in the new RR28Z.Â Hole RR21-28a returned 4.25 metres of 5.31 g/t AuEq or 398.09 g/t AgEq. RR21-28b returned 25.58 metres of 3.60 g/t AuEq or 271.16 g/t AgEq, including 2.30 metres of 10.95 g/t AuEq or 816.95 g/t AgEq.
There were successful RRMZ intercepts over broad step-outs beyond the current resource. Hole RR21-34 returned 4.64 metres of 3.94 g/t AuEq. Hole RR21-36 returned 5.50 metres of 3.65 g/t AuEq. Hole RR21-40 returned 3.00 metres of 11.48 g/t gold with no obvious association with arsenical sulphides (0.04 per cent arsenic).
John Mirko, president and CEO, commented: “The nine drill holes in this news release compile the final results of 42 underground drill holes of the 16,400-metre Phase 1 underground drill program at Revel Ridge. Over a short nine-month period, underground drilling at Revel Ridge continues to establish this gold-rich, polymetallic sulphide resource as one of the premier undeveloped gold deposits within the Western Cordillera. Within this large-scale structural and hydrothermal system spanning several kilometres, we have discovered the development of a previously undiscovered mineralized zone – the RR28Z – in addition to new southeast extensions to the RRYZ, and have the first indications for the development of gold mineralization within the RRMZ with a greatly reduced association with arsenical sulphides. As we move into the first phase of the surface drill program, we begin to target new gold-mineralized zones at very shallow depths with full knowledge that mineralization in this environment extends at the kilometre scale, both along strike and at depth.”
