Exploration

The Selinsing Gold Mine area exploration programs aim to further discover sulphide resources and Inferred into Indicated Resource, to optimize the economic results of the sulphide project and increase the life of mine, while locating more oxide and leachable sulphide mineralization to increase current mill feed.

Selinsing/Buffalo Reef/Felda

At both Selinsing and Buffalo Reef deposits the sulphide mineralization is still open down dip mainly, and also along strike. Exploration drilling was done testing and confirming the continuity of the mineralisation at Buffalo Reef deposits and of the high grade zone just beneath Selinsing Pit IV floor, also confirming the accuracy of the current Resource blocks’ locations and continuity of the gold high grade zone. Underground potential has been identified for high gold grade sulphide mineralisation at >3 g/t Au at both deposits, encouraging the development of sulphide deep drilling programs.

Exploration trenching and surface sampling were designed to verify opportunities for oxide supply to the current processing plant. Geo-metallurgical modelling for Buffalo Reef North (“BRN”) and BRS was completed. The estimated potential leachable gold for oxide and transition zones encourages follow-up confirmation work. Metallurgical testwork was also completed for BRC, and is being used for modeling and reconciliation exercises.

Exploration at Felda Block 7 aims to define oxide and sulphide resources to convert Inferred to Indicated Resources, discover new resources and enable the Buffalo Reef Central and Buffalo Reef South open pits to be extended at depth. Geo-metallurgical modelling has been completed for Felda, identifying significant blocks of leachable material within existing Felda Resource. High grade non-leachable blocks of transition sulphide mineralisation have been identified, which could be mined and stockpiled for the future sulphide flotation plant.

The significant drill intersections are in the table below, and additional drill results are listed in Table 1 in the news release dated April 11 2016.

Peranggih

The Peranggih area is located about 10km north of Selinsing and is in the same regional shearing structure as the Selinsing and Buffalo Reef gold deposits. Peranggih was historically mined in the late 1980’s and into the early 1990’s by local artisanal miners.

A drilling program at Peranggih together with previous exploration has successfully delineated a zone of higher grade gold material. The 2018 infill and extension drilling program is designed to cover strike and down dip extensions of the high grade mineralization area at an historical mining site at Peranggih North. This mineralization of 150m strike length x 80m width was identified in a 2017 drill program. The aim of the 2018 drilling is to test continuity of the mineralization, and to verify extension down dip and along the strike for other zones trenched and drilled previously including Peranggih South, North 114 and NW.

The recent 2018 drilling program completed so far confirmed the down dip extension and boundary refinement of several high gold grade (HG) zones surrounded by a main low grade gold (LG) halo in Peranggih North, and the identification of HG bodies that can be surrounded or not by LG halos at Peranggih South area. The more continuous significant drill intersections (Au >2.0 g/t & >2.5m length) are presented in the table above. The full set of drill results for the holes with significant intercepts are listed in Appendix A and Appendix B in the News Release dated July 16, 2018.

Figure 1 below shows the location of the 2018 drilling program completed for Peranggih in relation to the four mineralization zones, highlighting significant intercepts. Figure 2 below is the cross-section N479980 looking north, showing interpretation for LG and HG domains, and significant intercepts at HG domain.

The Company plans to carry out a 10,000t bulk sample testwork through the existing Selinsing oxide gold processing plant to establish the average grade of the close spaced drilled area at Peranggih North; and test the metallurgical performance at plant scale. This work can commence as soon as the access road has been prepared. Further infill/extension drilling targets have been identified around the higher to medium grade intercepts especially for Peranggih South. The extension drilling in the NW Peranggih area has also been planned to understand mineralization structure and to identify regional exploration targets.
