Commences Field Assessment of Regional Zinc VMS Targets
Leading into the 2018 field season, White Rock identified a number of high priority VMS targets outside the known high-grade zinc - silver - lead - gold VMS deposits at Dry Creek and West Tundra (refer ASX Announcement 13 September 2016 "White Rock identifies multiple zinc-silver VMS targets"). These high priority VMS targets are conductors located within zones of anomalous surface geochemistry that are indicative of proximal VMS mineralisation.
The VMS targets were identified utilising an assessment done by Dr Jim Franklin, a recognised global VMS expert, of existing surface geochemical data, in conjunction with a detailed interpretation by Condor Consulting, Inc., recognised experts in the field of airborne electromagnetics ("EM"), of an existing EM and magnetics survey.
Both Dr Franklin and Condor were able to use the known deposits at Dry Creek and West Tundra Flats to calibrate their assessment of the regional data. The resulting geochemistry assessment prioritises the Dry Creek West, ReRun, West Tundra, Rod, Smog and Glacier target areas as highly prospective for additional VMS deposits (see Figure 1 in link below), and Condor identified a number of high priority conductors as having the potential of being caused by massive sulphide mineralisation (see Figure 2 in link below). The highest priority conductors are located within the geochemical target areas, some of which are coincident with strong base metal and precious metal anomalies from historic sampling (Conductor 1 to 30).
Field crews have now commenced their field assessment at the highest priority targets with the intention of undertaking mapping and surface sampling prior to selecting targets for drill testing throughout the 2018 campaign (see Figures 3 and 4 in link below).
Field crews have already been able to assess conductivity targets 2, 3, 4, 5, 6, 8 & 9 as well as the associated proximal soil geochemical anomalies. Detailed mapping and sampling of prioritised prospects will now commence ahead of drill testing. It is anticipated a handheld XRF will be utilised to rapidly validate the location and tenor of historic surface zinc, lead, silver and copper anomalism prior to locating drill holes to test the new targets, without the need for samples to be submitted to the laboratory and subsequent long lead time to surface geochemistry results.

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.
