Drilling Update

Highlights:

• The drilling programme at Tripela on Exploration Licence 1462 (the “Tripela Prospect”) is progressing with the most recent four deep drillholes all intersecting inner-propylitic alteration. Due to these continuing positive results, the planned programme  for 4,000 metres has been extended with 4,600 metres already completed since June

• Independent analytical testwork on core samples from recent drilling at the Tripela Prospect confirms probable proximity to a fertile mineralised copper porphyry.

Papua Mining plc (“Papua” or “the Company”) a UK company focused on the exploration for and if commercially feasible, development of gold and copper deposits in Papua New Guinea (“PNG”) presents this update in respect of its drilling activities at the Tripela Prospect.

Tripela Drilling

Since the commencement of our drilling programme at the Tripela Prospect, we have completed approximately 6,800 metres of drilling.

Table 1: Diamond drillhole parameters for the Tripela Prospect drilling programme.

The initial drilling programme at Tripela, which was undertaken between January and May 2014, was designed to seek evidence confirming underlying porphyry emplacement in the area where our field teams had discovered significant occurrences of metal rich veins at surface.  The principal aim of that relatively shallow drilling was the recognition of the zonation of argillic, phyllic and propylitic alteration at Tripela that would lead us to an inner-potassic alteration zone which is in turn believed to be at the core of the porphyry deposit.

The first deep hole, DDH012, was completed in early-August 2014. DDH013 was completed in mid-September and DDH014 was completed on 17 November.   DDH015 commenced on 21 November and is now at a depth of approximately 1,070 metres.

The results at the Tripela Prospect have been consistently positive.  In particular, extensive epidote alteration, intersected in the last four holes drilled, has allowed us to start to define an inner propylitic alteration halo. It is stressed however that we have not yet intersected the mineralised potassic zone.

In early December we submitted rock and core samples for test work at CODES (ARC Centre of Excellence in Ore Deposits) at the University of Tasmania in Hobart.  CODES is undertaking cutting edge research on epidote chemistry in porphyry copper deposit environments. This new research is studying changes in the chemical composition of crystals of the mineral epidote around porphyry copper deposits.  Although at an early stage, the research is pointing to the possibility that the chemical signature of epidote could become a diagnostic tool for vectoring towards and assessing the fertility of porphyry copper deposits.

In late-December we received a preliminary report from CODES on the samples Papua took from the Tripela Prospect, Mt. Visi (Licence EL2051) and Ainbol (Licence EL2146) areas.  The key findings in the preliminary report are as follows:

• All samples from the Tripela Prospect contain epidote with a chemical signature which suggests either a very proximal position (<0.5 km) from the centre of a small porphyry deposit or a position proximal to the centre of a large deposit

• The sample from the Mt. Vesi Prospect contains epidote with chemical characteristics suggesting it originated around 1-2 km from a medium-sized porphyry centre.

Although this is new research in early stages of development, the findings are consistent with our own previously reported interpretations based on our drilling at the Tripela Prospect.  We also believe that the interpreted proximity of the Mt. Visi sample to a porphyry centre is potentially equally significant.

We now intend to drill an additional wedged daughter hole off the current drillhole as part of the current programme at the Tripela Prospect.  We expect that our drilling programme at the Tripela Prospect will be concluded in March 2015 and a full drilling report will be produced following completion of drilling activities.
