RNC Minerals Drills 21m of 7.09g/t gold at Beta Hunt Extending Western Flanks Gold Mineralization at Depth; Provides Exploration Update

TORONTO, June 26, 2017/ - RNC Minerals (TSX: RNX) ("RNC") announces continued positive infill and extension drilling results at its Beta Hunt Mine in Western Australia.

"The latest drill results from the Western Flanks Zone continue to demonstrate the immense potential to multiply the existing gold resource at Beta Hunt. The latest drilling confirms the extension of Western Flanks mineralization at depth in multiple holes, nearly doubling the vertical extent of Western Flanks mineralization to 190 metres below the contact. Current drilling has yielded the best intersections yet in the Western Flanks as hole WF18-028 returned 7.09 g/t gold over a downhole length of 21 meters. Infill drilling at Western Flanks and the A Zone Extension continue to return excellent results in terms of both grade and thickness, and we have added a second drill to allow us to accelerate our resource expansion efforts," said Mark Selby, President and CEO of RNC.

Drilling highlights at Western Flanks since RNC's news release dated April 10, 2017 include the following gold intersections:

Western Flanks (depth extension): (See Table 1 for full assay highlights)

WF18-010 – 17.85 m at 4.28 g/t including 3.00 m at 6.46 g/t

WF18-014 – 9.00 m at 3.35 g/t including 3.00 m at 4.20 g/t

WF18-028 – 21.00 m at 7.09 g/t including 16.25 m at 8.18 g/t

Western Flanks (infill): (See Table 2 for full assay highlights)

WF18-003 – 13.10 m at 4.53 g/t including 3.30 m at 7.55 g/t

WF18-007 – 2.90 m at 14.97 g/t including 0.60 m at 69.90 g/t

WF18-012 – 7.80 m at 5.82 g/t including 1.30 m at 26.50 g/t

See Figures 1, 2 and 3 showing location and proximity to existing development.

Additionally, further definition drilling to support the mine plan in the A Zone Extension has returned more positive results for defining a resource, including:

A Zone Extension (extension): (See Table 3 for full assay highlights)

WFE17-15 – 2.15 m at 8.47 g/t including 1.15 m at 13.17 g/t

WFE17-16 – 3.00 m at 4.57 g/t including 1.00 m at 8.02 g/t

WFE17-19 – 4.20 m at 4.08 g/t including 0.95 m at 14.70 g/t

See Figure 1 and 4 for location and proximity to existing development.

Beta Hunt A Zone Extension and Western Flanks depth extension and infill drilling

Additional drill holes completed since RNC's news release dated April 10, 2017 highlight the continuity of gold mineralization in the southern extension of the A Zone where RNC previously announced the extension of the strike length of 1.2 kilometres by a further 500 metres or more than 40%. The southern extension occurs directly below the previously mined contact-related historical Hunt nickel deposit (see Figure 4). Significant assays from the recent drill holes are provided in Tables 1, 2 and 3.

At the Western Flanks Zone, recently completed drill holes confirm the extension of Western Flanks mineralization at depth in multiple holes and locally extends mineralization by 90 metres below the deepest previous intersection. This increases the known vertical extent of Western Flanks mineralization by 90% to 190 metres below the ultramafic/basalt contact. The drilling also highlights the continuity of gold mineralization within the known resource and demonstrates gold mineralization extends well below the known resource and remains open at depth.

RNC recently added a second diamond drill at Beta Hunt to support infill and exploration drilling plans. Results will continue to be released as assays become available and will be utilized to update resource models.
