Laiva is classed as an orogenic gold deposit.

Mineralization comprises sheeted quartz-sulphide vein arrays within multiple, sub-parallel, mylonitic shear zone, hosted in metavolcanic and quartz diorite rocks. Mineralization occurs in two main bodies, the North Pit with Eastern Extention in the north, and the South Pit in the south.

At the North Pit, mineralised shear zones can be traced over a strike length of up to 600m, with the mineralized zone (including the Eastern Extention) occurring over an area of 1300 m by 450 m. In the South Pit area, mineralization occurs over an area of 500 m by 400 m. Mineralization has been intercepted at depths of up to 250 m below surface and is open down pit, apart from the western part of the North Pit where mineralization is truncated by the granite pluton. In both the North and South Pits, the mineralized shear zones vary in windth between <1 m to >10 m.

The mineralised shear zones display distinct structural trends in differetn parts of the deposit, with the orientation being dependent on proximity to the Red Shear Zone. West of the Red Shear Zone, mineralised shear zones strike east-northest and dip steeply (78 degrees to 85 degrees) south-southeast. Immediatly east of the Red Shear Zone, mineralised shear zones strike east-northest and dip steeply west- southwest, transitioning to av almost easterly strike wuth southerly, steep dip progressively to the east.

The Laiva Project is composed of a single project with three mining areas: the previously developed South Pit in the southwestern portion of the project; the previously developed North Pit area in the northern portion of the project; and the East Pit area located east of the North and South pit areas.

Standard mining technology has been utilized to create an open pit at each of the two mining areas. The South Pit has approximate dimensions of 620 m south to north by 540 m east to west and a maximum depth of 200 m below current ground level. The South is composed of three mining phases. The North Pit has approximate dimensions of 840 m south to north by 600 m east to west and a maximum depth of 170 m below current ground level. The North Pit is composed of four mining phases. All of the pit shells were selected from the Whittle open-pit optimization discussed below and were used to guide the design of two mining areas.

A mine contractor has been engaged by OTSO who will be used for most mining activities including site preparation, haul road construction and maintenance, mineralized material and bulk waste drilling and blasting, excavation and haulage of mineralized material and waste, management of waste dumps, oversize breakage, and pit dewatering. The mine contractor will provide all mining equipment. The contractor will provide operator training, supervision, mine consumables, and maintenance facilities for contractor’s operations.

The mineral processing plant is located approximately 1 km northeast from the South and North open pits on the LGP site. Processing consists of three primary circuit components, including: crushing and grinding, pre-concentration by flash flotation and gravity concentration, followed by High and Low grade CIL leach circuits. Design throughput rate is 250 tons per hours (6,000 mtpd / 2 M mtpy).

Flash Flotation and Gravity Circuits
From the sieve, the undersized flows by gravity to a sump and is pumped to the flash flotation circuit. The Flash Flotation unit (Metso Unit Cell RCS 30) produces high grade concentrate of gold-bearing sulphide minerals including arsenopyrite and pyrite. Copper sulphate (CuSO4) is added to activate arsenopyrite and PAX (Potassium Amyl Xanthate) and Aerophine 3418A are used as collectors. The produced concentrate is directed to the concentrate regrind circuit for onward direction to the high grade CIL circuit.
