The maiden resource for the project consisted of 32Mt indicated and 189Mt inferred.
The Middle Gobi update follows a recently announced maiden JORC resource upgrade of 63.1Mt at its South Gobi project, bringing the total JORC-compliant resource for its Mongolian projects to 248Mt of coking and thermal coal.
To date, geologists working at the Middle Gobi project have mapped approximately 4km of coal seam outcrop on the Tsakhiurt Gobi deposit (EL12929X).
Guildford said drilling at the deposit would recommence in March next year following shutdown for the winter period.
The Middle Gobi project, comprised of two exploration licences in the Dundgovi province, is located approximately 200km south of Ulaanbaatar and more than 200km west of the Mongolian railway grid.
Guildford said coal from the Middle Gobi project could be trucked to the Trans-Mongolian railway, where it could then be transported by rail to Chinese and Russian markets.
The two Middle Gobi project exploration licences have an approximate area of 36,000 hectares and are located in the coal-bearing Ongi Gol Basin.
Meanwhile, Guildford’s South Gobi project area consists of five exploration licences located in the South Gobi province (Umnigovi Aimag) of Mongolia.
The licences are situated approximately 1000km southwest of the Mongolian capital of Ulaanbaatar and approximately 60km from the Chinese border station of Ceke, where coal from Mongolia is transported through to China.
