PepinNini Minerals (ASX: PNN) is pleased to advise that it has completed reconnaissance vacuum soil

PepinNini Minerals Limited is a diversified ASX listed Exploration Company focused on developing and discovering major new mineral deposits. The Company has secured strategically located exploration tenements in the Musgrave Province of South and Western Australia, the Woolgar Goldfield/Georgetown Inlier of North Queensland and the Robinson Range Iron Ore Province of Western Australia. A portfolio of prospective exploration tenements

has recently been established in

Argentina.

geochemical drilling at the Central Plains-Wandilla Prospect which is part of the company's Caroline Project in the Musgrave Region of South Australia (Fig. 1). The project is being explored for magmatic nickel-copper sulphides associated with layered mafic intrusions within Caroline EL5220 (100% PNN).

The recent program of vacuum drilling at the Central Plains - Wandilla prospect area(ASX announcement 21 April 2015) to collect soil and regolith samples has been completed. The activities were designed to investigate subsurface geochemical distributions within the regolith to enhance bedrock geological mapping, reinforce geophysical target selection, and detect zones of geochemical anomalisms. The programme involved 253 vacuum drill holes (for a total 3004metres) across previously unexplored portions of the EL5220 tenement (fig. 2).
One hundred seventy one(171)reconnaissance holes at 100-200m centres were completed along widely spaced traverses across prospective geological and structural environments identified from airborne magnetic mapping. Regolith samples from ten of the holes have returned weakly anomalous nickel-copper-cobalt +/- platinum group element (Ni-Cu-Co - PGE) geochemical results which may indicate
fertile mafic stratigraphy in the underlying basement rock (Fig. 3). Maximum results of 265ppm Ni, 216ppm Cu, 196ppm Co, 5ppb Au,
7.1ppb Pt and 16ppb Pd were returned from the batch of samples analysed. Anomalous sample results are presented in Table 1.
The most encouraging results form a northwest-southeast trend of Ni- Cu-Co-PGE anomalism extending across on three adjacent traverses with a potential length exceeding three kilometres (Figure 3). These anomalous results include:

VCS0037 : 217ppm Ni, 89ppm Cu, 196ppm Co, 15.1ppb PGEsVCS0161 : 265ppm Ni, 71ppm Cu, 43ppm Co, 16.1ppb PGEsVCS0148 : 47ppm Ni, 216ppm Cu, 35ppm Co, 19.1ppb PGEs

(PGEs = Au+Pt+Pd, see also table 1)

Follow up vacuum soil drilling has been conducted to infill and extend the geochemical coverage around these target zones. Eighty two (82)additional holes were completed and regolith samples have been collected and are being submitted for analytical testing as soon as possible.

The vacuum drilling activities have assisted the mapping of cover soil-sand and is adding to the validation of interpreted bedrock mapping derived from the historic airborne magnetic data.The results will, in conjunction with the CSIRO airborne electromagnetic surveys scheduled to commence in the next two months, help identify and rank magmatic nickel-copper targets for more extensive bedrock drill testing using the company's diamond drill rig.
