White Rock drill Intersections extend mineralisation at Red Mountain

White Rock Minerals Ltd announced that assay results for massive sulphide mineralisation intersected in the first two diamond drill holes targeting the down plunge extension of mineralisation in the Discovery lens and the Fosters lens of the Dry Creek deposit at its 100% owned high-grade zinc VMS project at Red Mountain in Alaska. The Discovery lens interval corresponds with the visible sulphide mineralisation previously reported, as shown in Figure 1.

1. The first two drill holes of the 2018 program to test the down plunge extension of mineralisation at both the Discovery lens and the Fosters lens at the Dry Creek deposit have returned exceptional zinc, lead, silver and gold grades:

o 4.7m @ 19.5% zinc, 7.8% lead, 466g/t silver, 6.9g/t gold and 1.5% copper for 49.7% ZnEq(see Note below) (DC18-79), including 1.6m @ 18.5g/t Au.

o 4.3m @ 4.8% zinc, 2.3% lead, 1,435g/t silver, 2.2g/t gold and 0.5% copper for 43.2% ZnEq(see Note below) (DC18-77).

2. The Discovery lens hole (DC18-79) intersection is the best result of all the historic holes drilled into the Discovery lens.

3. This drilling extends the high-grade Fosters and Discovery Lenses and highlights the exceptional growth potential as the mineralisation remains open.

The diamond drilling results are part of White Rock's maiden drill campaign at the Red Mountain project. Drilling is now targeting extensions of the two existing deposits, Dry Creek and West Tundra, which already have a Resource base of 16.7Mt at 8.9% ZnE including a high-grade component of 9.1Mt @ 12.9% ZnEq.

Mr Matt Gill MD & CEO said that "This drilling represents a significant extension to the Dry Creek deposit and notably down dip at both the Fosters and Discovery lenses. These first two extension drill holes highlight the upside potential for a significant expansion to the Resource at Dry Creek, both in terms of grade and size. Dry Creek is an exciting VMS deposit as it shows great variation in thickness that has the potential to rapidly add to the Resource. These current drill holes also highlight the potential for significant high-grade gold and silver with individual assays up to 25g/t Au and 1,795g/t Ag. In addition, we are continuing to see more copper as we explore to the east, supporting an early interpretation that the VMS system may be improving towards the east and at depth, where improving zinc grades could also be expected. And all this before we have really got our teeth into testing some of the best of the more than 30 already identified regional exploration targets within our 143km2 land package."

The drill program continues to test extensions of the Discovery lens with a further two drill holes completed and another drill hole underway. The long-section and cross-section presented in Figures 2 & 3 illustrate the upside potential for down-plunge mineralisation extensions. The Dry Creek deposit shows typical pinching and swelling of mineralisation as is often encountered in other VMS deposits, underlining the upside potential for down-plunge and along strike Resource expansion through drill testing.

In addition to drilling at the Discovery lens, results for the first drill hole testing the down plunge extension of mineralisation at the Fosters lens of the Dry Creek deposit have also been received. DC18-77 intersected two zones of semi-massive sulphide mineralisation. The lower zone returned exceptional silver mineralisation.
