VANCOUVER, British Columbia, Sept. 12, 2017 (GLOBE NEWSWIRE) -- OK2 Minerals Ltd. (TSX-V:OK) (the “Company”) is pleased to announce surface sampling results from the Kinskuch Property have now been received. Field crews completed a month long mapping plus silt and rock sampling program which included visiting all three targets within the Kinskuch claim package: Big Bulk, Golden Mickey, and the VMS claims. More than 300 rock samples and five silt samples have been collected to date in 2017.
Highlights
- 42 samples over 2.25km trend at Big Bulk Target average 0.57% Cu and 0.35 g/t Au
- Notable values include 2.84 g/t Au, 1.79% Cu (D00015631) and 2.02 g/t Au, 1.54% Cu (D00015624)
- New model suggests target is a much larger gold rich calc-alkaline porphyry system than historical work indicated
- High grade sample from Golden Mickey target include 24.2% Cu, 7,688 g/t Ag, 16.5 g/t Sb, and 1.45% Zn
The 2017 program was designed to test a new interpretation developed in conjunction with the BC Geological Survey (BCGS) and University of British Columbia (UBC) that indicates that the system is tilted with a surface expression of over 3.5 km. Historical work has assumed that the Big Bulk porphyry system is an upright and a lower tonnage alkalic porphyry system. Based on this summer’s exploration, the company now believes the target is a much larger gold rich calc-alkaline porphyry system.
The new interpretation of the porphyry system being tilted on its side, means that deeper core zone alteration and mineralization which is typically tested with deep drilling is now present at surface. Sampling and mapping was focused on identifying and characterizing core zone alteration which consists of sheeted quartz veins with disseminated and vein hosted chalcopyrite within a chlorite altered diorite host. Historical sampling on the property largely targeted what is now believed to be late mineral intrusive bodies and downgraded phyllic alteration zones.
New rock sampling from outcrops in these regions of interest has returned very promising results over 2.25km of trend with 42 outcrop grab samples returning an average of 0.57% Cu and 0.35 g/t Au. Notable grab samples (Table 1) include values as high as 2.84 g/t Au, 1.79% Cu (D00015631) and 2.02 g/t Au, 1.54% Cu (D00015624). These rock samples come from areas with limited or no historic sampling and some are from areas of recent glacial retreat.

| Sample No | Au (g/t) | Ag (g/t) | Cu (%) |
| D00015624 | 2.02 | 9.31 | 1.54 |
| D00015631 | 2.84 | 6.74 | 1.79 |
| D00015638 | 0.51 | 5.93 | 1.25 |

| D00015653 | 0.65 | 2.32 | 1.02 |
| D00015658 | 0.42 | 12.3 | 1.42 |
Sampling outside of these stockwork zones also returned significant values up to 12.5% Cu (D00015665) from poddy chalcopyrite mineralization within silicified diorite as well as quartz veins and epithermal veins. Table 2 highlights several of these samples.

| Sample No | Au (g/t) | Ag (g/t) | Cu (%) |
| D00015665 | 0.09 | 30.1 | 12.5 |
| D00015615 | 2.39 | 3.38 | 5.12 |
| D00015616 | 2.7 | 13.3 | 3.77 |
Field crews spent two days visiting the Golden Mickey target examining the area around a historic adit and to confirm the style of mineralization present. One sample (D00015534) returned 24.2% Cu, 7,688 g/t Ag, 16.5 g/t Sb, and 1.45% Zn. The mineralization is characterized by a 30cm wide lens of massive tetrahedrite, chalcopyrite, and malachite within argillites that dips at a shallow angle into the cliff face. Given the proximity to the Dolly Varden Silver property and their ongoing success, this area remains of interest.
Due to poor weather conditions for helicopter access, limited work was performed on the VMS claims. An attempt was made to locate areas of sericite altered volcanics with the best sample returning (D00015656) 0.11 g/t Au, 5.91 g/t Ag, and 3.08% Zn. In addition, one of the five silt samples collected this summer from the VMS claims from creek contained entirely with the company’s claim block, returned a value of 0.65% Cu and 0.65 g/t Au. Follow up mapping and sampling is required in the area of this anomalous silt sample result.
OK2 Minerals is awaiting results from its Airborne ZTEM survey being flown in conjunction with the Hecla Mining Company. Future drill targets will be selected based upon the interpretation of these results in conjunction with anomalous rock and silt samples and new interpretations derived from geological mapping.
