The Segilola deposit comprises a single style steep dipping vein-hosted gold deposit.

The mineralized lodes generally comprise highly silicified fine-grained foliated biotite gneiss typically intruded by both discordant and concordant pegmatitic quartz-feldspar veins.

Minor sulphides, typically pyrite, is associated with the lode. Macroscopic observations show that sulphide grains and blebs are often aligned with foliation, commonly following either biotite-rich laminae or near pegmatite boundaries.

There is also, however, a common generation of pyrite occurring along fractures or as quartz-pyrite tension gashes, highly discordant to the foliation. Cursory examination suggests most of these do not contain pyrrhotite, but this needs to be confirmed. These either relate to a late episode of mineralisation, or to remobilization of sulphides.

Visible gold is commonly logged as occurring both in altered wall rock (usually gneiss) and in quartzfeldspar veins. Hansa GeoMin reported that native gold occurs with petzite (a silver gold telluride) within pyrite and quartz veins. Typical size of native gold blebs about 10 microns.

Shearing, fracturing and alteration influence the locality of gold mineralization. At Segilola, this is not a complicated relationship and it has generated a single long zone of gold mineralization hosted by a shear now represented by chlorite and calcite alteration, together with quartz veining and pyrite development. Gold, either as native grains, flakes and blebs occurs together with gold-on-pyrite in alteration zones, along tension gashes, hair-like fractures, joints and minor faults. The mineralized zone forms essentially a single elongate body varying from a 2 metres to over 20 metres thick, is 2,000 metres in strike and between 70 and 200 metres in depth.

The northern extension of mineralization is pinching out and the northern-most 5 boreholes intersected poor veining and no gold. The southern extension appears to plunge below the village of Iperindo, though there are also thinner intersections and poor grades in the southern-most
boreholes.

The planned open pit is 1,600 m long, 140 m to 430 m wide, 55 m to 210 m deep, and covers an area of 43 ha. Three pushbacks are planned, The proposed open pit mining method utilises an excavator and truck fleet for both ore and waste. A large part of the mined material will require drill and blast.

Mining operations last for 45 months, with processing continuing for a further 19 months. Sizable stockpiles are created, allowing processing to continue for some time after mining ends. Mining in advance of the processing demand allows the ore supply to be smoothed out and also allows better grades to be processed earlier in the overall schedule.

A detailed mining schedule has been developed that requires minimal pre-stripping prior to plant commissioning. Production will initially commence from the high grade northern pit, which outcrops at surface and along with the Stage 2 pit which commences after nine months will return an average head grade of approximately 6.3g/t for the first 12 months of operation. Stage 3 commences in month 14 upon the completion of Stage 1, with a cut back of the southern wall of the Stage 2 pit to the final pit design. The mining schedule incorporates stockpile management such that processing plant feed grade is smoothed in order to optimise project cash flows.

The processing plant will have a throughput rate of 625,000 tonnes of ore per annum. ROM ore will be delivered from the mine to the processing plant, which consists of a conventional crush, grind, gravity, and leach process, followed by carbon adsorption and then elution at high pressure and temperature, electrowinning, and doré bar production by induction furnace. Leach tailings will be treated using the SO2/air process to destroy cyanide in the tailings, prior to being pumped to the TMF. Water will be recovered and pumped back from the TMF to the processing plant for re-use in the process. The plant will operate on a 365 day/year, 24 hour/day operating cycle. Gold is to be extracted by conventional carbon in pulp, to produce a gold dore via elution, electrowinning, and smelting. Life of mine average recovery is estimated to be 97% resulting in life of mine production of 393,400 ounces.
