Further development of Amaam North, which includes an upgrade of mine site infrastructure, the Beringovsky Port and Coal Terminal and to be supplemented by the construction of a coal handling and preparation plant (“CHPP”), will enable the Group to produce and sell higher-value coal and is expected to increase coal sales up to 1.4Mtpa. |

Summary:
Amaam North is part of a tectonic basin of the Cenozoic Anadyr-Koryak fold system. The basin is a symmetrical graben structure with large fold structures, and evidence of both normal and thrust faulting is present. Basement sediments of the Project F syncline are made up of the regionally extensive Baryskoskaya and Koryak Formations.
The lower Chuckhi sub-formation is represented mainly by sandstones, conglomerates, and to a lesser extent, siltstones, mudstones, tuffs, and the Project F Coal Seams. The thickness of the sub-formation varies from 200 to 400m, averaging 300m (Fandyushkin et al, 2017).
The seams extend along approximately 8km of strike, generally dipping towards the north, but also wrapping around an east west oriented anticline in the west. The deposit is open along strike to the east, and at depth to the north. The portion of the resource amenable to economic extraction via open cut methods has been limited to 300m depth. The underground extractable portion of the resource extends to an approximate maximum depth of 400m.
Summary:
The current mining method for the project is truck and shovel open cut.
A preliminary limit for eventual economic extraction via this method has been determined as: The lesser of 25:1 (BCM waste:tonnes coal) vertical in situ strip ratio or 300m depth.
All coal seams that meet this limit, and have a raw ash of <= 50% have been included in the resource estimate.
Beyond this limit, Seam 4 only has been considered to have potential for eventual economic extraction via underground methods.
Summary:
Seam 4 is currently being mined and sold as a bypass product.
In October 2020 TIG signed a contract for supply of a modular CHPP with DPCI. Work under the contract is proceeding on schedule for delivery to Beringovsky in June 2021. Detailed engineering works and preparation for civil construction are also underway. TIG expects commissioning works to be finished in 2021 so as to allow the first SHCC product to be sold during the 2021 shipping season.

Reserves at November 24, 2020:
A raw ash cut-off of 50% has been applied to all seams, which is in line with the generally accepted definition of coal.
