- VMS deposits typically occur in clusters ("VMS camps"). Deposit sizes within camps typically follow a log normal distribution, and deposits within camps typically occur at regular spacing. The known deposits at Dry Creek and West Tundra Flats provide valuable information with which to vector and target additional new deposits within the Red Mountain camp.
- Interpretation of the geologic setting indicates conditions that enhance the prospectivity for gold-rich mineralisation within the VMS system at Red Mountain. Gold mineralisation is usually found at the top of VMS base metal deposits or adjacent in the overlying sediments. Gold bearing host rocks are commonly not enriched in base metals and consequently often missed during early exploration sampling. This provides an exciting opportunity for potential further discoveries at Red Mountain.
- White Rock sees significant discovery potential, given the lack of modern day exploration at Red Mountain. This is further enhanced by the very nature of VMS clustering in camps, and the potentially large areas over which these can occur.
Note: ZnEq = Zinc equivalent grades are estimated using long-term broker consensus estimates compiled by RFC Ambrian as at 20 March 2017 adjusted for recoveries from historical metallurgical test work and calculated with the formula: ZnEq =100 x [(Zn% x 2,206.7 x 0.9) + (Pb% x 1,922 x 0.75) + (Cu% x 6,274 x 0.70) + (Ag g/t x (19.68/31.1035) x 0.70) + (Au g/t x (1,227/31.1035) x 0.80)] / (2,206.7 x 0.9). White Rock is of the opinion that all elements included in the metal equivalent calculation have reasonable potential to be recovered and sold.

About White Rock Minerals Ltd
White Rock Minerals Ltd ( ASX:WRM ) is an Australian listed minerals exploration and development company with projects located in northern NSW (gold and silver) and central Alaska (zinc, silver, lead and gold). The White Rock vision is to explore and develop both precious and base metal projects.
White Rock's cornerstone asset is the Mt Carrington epithermal gold-silver project in northern NSW. The Mt Carrington project has great leverage to the Australian gold and silver prices with a positive scoping study providing a path towards feasibility studies and development in the near term.
White Rock is also exploring the Red Mountain project in Alaska. Red Mountain is a globally significant advanced VMS project with high grade zinc and silver in two deposits. White Rock is exploring for additional high grade deposits that will enhance the projects leverage to an upturn in the fortunes of zinc and silver.
