Segilola is an orogenic-style lode gold deposit which occurs within a regional-scale shear zone.

Host rocks comprise an overturned sequence of high-grade amphibolite-facies metasediments intruded by a large, possibly differentiated, granodiorite sill-like body. The mineralisation is developed within a series of steeply dipping, tabular, very continuous, late stage quartz-pegmatite veins that do no exhibit any form of significant deformation such as folding or faulting. The geological and mineralogical characteristics of the mineralised veins are consistent throughout both the strike and down dip extents of the known resource.

Drilling results demonstrate that gold mineralization occurs in fractured pale to dark grey coloured smoky quartz veining, sheared pegmatite, and silica/chlorite/carbonate alteration. The mineralization is hosted in three steeply dipping vein sets or lodes; the Hanging Wall Lodes (Lodes 100 and 300, and minor lodes 400, 500 and 600) and the Footwall Lode (Lode 200). Together these form an elongate mineralized zone striking 010° and dipping 60° to 70° towards the west within a developed shear zone, primarily in biotite gneiss. The currently drilled mineralized zone is approximately 2,000 m in strike length, between 70 m and 200 m in depth, and between 2 m and 18 m in true thickness.

The mineralogy of the Segilola deposit is characterised by its general simplicity and consistency. The gold is entirely non-refractory and co ........

The project is a conventional open cut operation utilising a fleet of drill and blast, load and haul equipment. SROL has engaged SINIC as the primary contractor to manage the mining contract which entails drill and blast, load and haul summarised accordingly:
• Owner; SROL.
• Principal Contractor; SINIC.
• Sub-Contractors; Sino-Hydro (Load and Haul) – Auxin (Drill and Blast).

Grade Control
Conventional open pit grade control practices will be used at Segilola Mine, incorporating RC drilling and sampling on a suitably designed drilling pattern and to cover three successive 6.0 m benches (6 x 3.0 m mining flitches).

Drilling and Blasting
Blasthole drilling will be conducted with track-mounted mobile drill rigs PowerROC D55 and the XuanHua 370 for the production and presplit drilling respectively. Current blast design is based on a 127 mm diameter hole. Blastholes are drilled for a 6 m bench height, with a 1 m sub-drill. Drilling for 6 m bench height is done with 115 mm diameter holes when required, with a 0.5 m sub-drill. However, it is possible to use a tighter space drill pattern using 89 mm diameter blast holes where the need for a high degree of selectivity is beneficial when attempting to minimize ore loss and dilution. There are several rock types and three weathering types in the pit that differ in the required powder factor to effectively break the rock so as to optimize blasting efficiency and fragmentation.
