Quarterly Activities Report September 2018
WETAR COPPER PROJECT (FINDERS 74.1%)
OH&S
At the end of the September quarter Wetar operations achieved 1.8 million hours without a lost time injury resulting in the twelve-month rolling Lost Time Injury Frequency Rate (LTIFR) at the end of the September 2018 quarter falling to 0.36 versus 0.70 in the corresponding September 2017 quarter. There were no lost time injuries recorded during the quarter and the Total Injury Frequency Rate (TRIFR) has reduced to 1.07, versus 4.20 in the corresponding September 2017 quarter.
Production
Mining and stacking of fresh ore increased over the quarter as remining of existing heaps tapered down in August and September in particular. This has resulted in an increase of 78% of total copper metal mined over the previous quarter (15,846 versus 8,903 contained tonnes of copper). Higher copper grades than anticipated in the lower levels of the Kali Kuning pit have positively contributed to this increase in contained metal mined. While there was a 4.4% increase in the recovered copper to 4,459 tonnes it does not correspond to the increase in stacking due to the longer leaching time and more complex metallurgy of the deeper ore. Mining and processing production data for the Wetar Copper Project is summarised in the following table:

Quarterly Activities Report September 2018
Mining
During the quarter, ore supply from the Kali Kuning open pit totalled 497,230 tonnes at a grade of 3.19% copper. The increase in ore supply represents the reduction of heap leach pad re-mining activities and the prioritisation of crushing and stacking of fresh ore as discussed further below.
A second major slip occurred on the north wall of the Kali Kuning pit (ASX announcements 3 October 2018 and 18 June 2018). Remediation works to remove approximately 300,000 bcm of waste have commenced and are expected to be completed over the fourth quarter. This additional waste movement may reduce the ore mined over the December quarter by 10%, however, it is not expected to lead to any delays to the commencement of the 2019 mine plan. No injuries were sustained during this incident. The Stage 6 cutback of the Kali Kuning western wall has commenced to facilitate access to ore in the Kali Kuning pit during the slip remediation works.

An updated Mineral Resource and Ore Reserve Estimate as at 30 June 20181 on a 100% owned basis was released to the ASX on 22 October 2018 and included:
§
198kt of copper metal contained in a 9.39 million tonnes mineral resource estimate at an average grade of 2.11% copper; and

§
188kt of copper metal contained in 9.06 million tonnes ore reserve estimate at an average grade of 2.08% copper.
The previous estimate was effective as at 1 December 2017 update. No additional data has been collected or recalculated since this last estimate, with changes reflecting mining depletion only. The Ore Reserve to actual ore mined reconciliation continues to remain positive. As at 30 September 2018 an additional 10.7% ore (551,830 tonnes) and 20.8% copper metal (24,041 tonnes) have been extracted from the pit and placed on the heap leach pads compared to the Ore Reserve. Competent person statements for this Ore Reserve update is available on the findersresources.com website.
Heap Leaching Operations
The rate of leaching is slower than projected by the feasibility study leach curve. Studies and analysis are ongoing to understand the reasons for this and whether terminal recoveries will be achieved. To compensate for slower leach rates the rate of stacking is being accelerated. Approximately 440,231 tonnes of fresh ore was crushed and stacked during the quarter, placing 14,739 tonnes of copper on the heap pads, up 60% from the previous quarter. Copper metal leached totalled 5,090 tonnes, being 91% of the previous quarter, due to heap re-mining activities. The daily leaching rate for the quarter was 55 tonnes per day. Accelerated stacking rates are expected to result in higher copper leach rates in the coming quarters.
Works have also commenced to extend the heap pads in the Kali Kuning Valley at KK1/2 and KK06 areas.

SX-EW Plant Production
Copper stripped was 4,459 tonnes versus 4,273 tonnes in the June 2018 quarter. This represents a slow but steady increase on the low of 4,100 realised in the December 2017 quarter. These improvements are attributable to better availability of the neutralisation plant and some benefits through optimising the neutralisation process.
However, the key constraint to increasing copper plating rates continues to be the level of free acid, which impacts SX plant extraction efficiencies. The average efficiency of the solvent extraction plant remains around 46% (vs budget 80%) as the free acid level continues to be persistently above 40 g/L. Neutralising plant capacity remains insufficient to reduce this free acid level and a major upgrade to the neutralising plant is scheduled for the first quarter of 2019.
As noted above an increase in the rate of mining, crushing and stacking fresh ore to increase the leached copper inventory has been undertaken. The resulting higher PLS copper grade should gradually improve production at higher acid levels, albeit at lower plant efficiency.
