DISTRICT GEOLOGY
The Almas Gold Project is situated in an historical gold mining area with numerous small artisanal mines (garimpos) and the former Vale Paiol Gold operation. Gold occurs in sheared metavolcanic rocks within the greenstone sequence, as well as in sheared felsic intrusive rocks. The rocks are, in general, Paleo-Proterozoic in age (~2.2 billion years old) and have undergone regional metamorphism ranging in intensity from greenschist- to amphibolite-facies. The metamorphism resulted in deep-seated, shearhosted, mesothermal, gold deposits which have more recently been referred to as orogenic gold deposits. The gold-mineralized zone occurs in the core of hydrothermal alteration zones, generally associated with variable amounts of quartz, carbonate, albite, sericite and sulphide minerals.

DISTRICT MINERALIZATION
Gold mineralization is found in three groups of rocks, in metabasalts of the Córrego Paiol Formation, in metasedimentary rocks of the Morro do Carneiro Formation and in granite-gneiss complexes.

Several occurrences of gold are hosted in the metabasalts, mainly south of Almas, the most important being that of the Córrego Paiol mine. The occurrences hosted in metasedimentary rocks are dominant in the southern portion of the terrain, Conceição do Tocantins region, while the occurrences in granite-gneissic rocks are distributed throughout the granite-greenstone terrain.

MINE OPERATION
The mining operation concept for the Almas Gold Project is conventional open pit mining with production schedule that provides an initial 0.6 Mt stock of ROM with 0.92 g/t Au content, equivalent to six months. Commercial operation is scheduled to start up in July, 2022 with a ramping up until October, 2022.

The mine development is planned to allow access to those grade levels to maximize gold production and provide operational flexibility by mining several benches simultaneously. The number of pits mined simultaneously will be no more than two pits.

The waste rock comprises soil, saprolite, weathered and fresh rock. The excavation of these deposits requires the use of drill and blast.30% of saprolite will require explosives. Load and haulage will be performed by a combination of front-end loaders, hydraulic excavators, and on-road trucks.

Benches will be configured as follows:
• A minimum mining width of 30 m on a 10 m-high bench has been maintained for Cata Funda, but Vira Saia and Paiol include a final bench access incorporating an operational mining width of 15 m to maximize access to the mineralized zone.
• The waste and ore benches will be mined as 5 m thick layers, leaving a designed 10 m maximum bench height.
• The ore and waste zones have been analysed and it is possible to operate with a proper berm width and in-pit dumping operational space.
• The benches will have a slight de ........

OVERALL PROCESS DESIGN
The process design is based on the results of several testwork programs. This includes testwork completed for the feasibility study and historical testing. Historical testing evaluated different flowsheet options.

The flowsheet selected for the feasibility study is based on typical industry unit operations for gold processing plants. The flowsheet includes primary crushing followed by grinding to achieve a particle size distribution of 80% passing 75 µm. Part of the cyclone underflow will be processed in a gravity circuit and the cyclone product (overflow) will feed a pre-leach thickener, with the underflow processed through a leach/carbon in leach (CIL) circuit. CIL tailings will be treated for cyanide destruction. The carbon from CIL will go to elution, regeneration and the final solution will go to electrowinning and the gold room.

Key process design criteria are listed below:
• Nominal throughput of 3,560 t/d or 1. ........
