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 mine is to be developed in three stages, incorporating two interim stage pits. Mining operations will be carried out using conventional drill and blast and load and haul mining methods with 3.5Mt of ore and 62.0Mt of waste being extracted over a period of seven years.

ROM ore will be delivered from the mine to the processing plant, which consists of a conventional crushing circuit and a single stage grinding circuit to achieve a target grind size P80 of 106 microns. The plant will operate on a 365 day/year, 24 hour/day operating cycle with a design plant availability of 91.3% for a nominal ore throughput of 62.5 tph resulting in a throughput rate of throughput rate of 500,000 tonnes per annum. Gold is to be extracted by conventional carbon in leach, to produce a gold dore via elution, electrowinning, and smelting.
