Papua Mining, a UK company focused on the exploration for and if commercially feasible, development of gold and copper deposits in PNG, has delineated the Tripela prospect on New Britain as its primary focus in the search for a buried porphyry copper-gold deposit. This follows the first phase of drilling on Tripela which was completed in early May.
Papua has approximately 2400sqkm comprised in 12 exploration licences in Papua New Guinea. Eleven of these licences are on the island of New Britain. Extensive 'boots on the ground' exploration has been carried out across the licensed area and the company has defined three main anomalies, namely the Flying Fox, Junction and Tripela drill targets in the EL1462 tenement area.
In total, just over 4000 metres of diamond drilling has been completed at the Junction, Flying Fox and Tripela targets, and drilling in mid-2013 at Junction intersected strong indicators of porphyry development, but at deeper levels than drilled at that time.
The recent drilling program at Tripela has collected essential vectoring geological information to map the alteration halo of the inferred porphyry target.
In addition, assay results have been received for rock samples collected by the company's reconnaissance geological team on the EL2051 tenement area during March and April. Of the 326 samples collected, 28 returned gold values greater than 1 gram/tonne. A maximum grade of 35.5 grams/tonne was returned from an outcrop sample.
Soil and rock sampling at Tripela, followed by geological and alteration mapping, culminated in the commencement of a relatively shallow, vector drilling program in January 2014, designed to test for alteration mineralogy and other data which would enable Papua Mining to vector towards the buried porphyry body interpreted from geological evidence. That initial shallow vectoring program has been completed for a total of 2100 metres of drilling. A number of holes in this program intersected broad zones of visible copper mineralization which, although not of economic grade, represent further positive vectors towards the projected deeper porphyry.
These results combined with the surface discovery of high grade copper mineralization in outcrops, many of which are interpreted as D Veins, point to the likely presence of a porphyry nearby. The company is now using these results to update the geological model for the target.
While drilling at Tripela was ongoing, Papua Mining continued with a modest but focused regional exploration program on its other licences. www.papuamining.com
