ization and Deposit Types

The Korean Peninsula
is situated on the eastern margin of the North China-Korea Platform, which corresponds to a craton composed of three blocks: Archean
metamorphic rocks, the Nangrim-Pyeongnam Block and the Gyeonggi and the Yeongnam Massifs. These blocks are separated by the northeast-trending
Imjingang and Okcheon mobile belts of Phanerozoic age. The Sangdong Mine is located within the northern sector of the Okcheon Fold Belt,
occupying the Cambro-Ordovician Joseon Supergroup of the Taebaek Basin.

The Sangdong Mine
is situated on the gently dipping southern limb of the east-west orientated Triassic-age Hambaek Syncline. This structure consists
of a thick sequence of sedimentary rocks of the Taebaek Series, composed of Cambro-Ordovician interlayered limestones, shales and quartzites
of the Joseon System. This sequence is unconformably overlying the Pre-Cambrian schist and gneiss basement of the Yulri Group of the
Yeongnam massif. The stratigraphy in the Sangdong area is mainly composed of the basal Jangsan quartzite, Myobong slate and the overlying
Pungchon limestone formations with Cambrian age, which belong to the Joseon Supergroup.

The tungsten mineralization
of the Sangdong deposit is contained in several tabular, bedding-conformable skarns in the Myobong Shale formation. The ore deposit is
strata-bound, with the strike and dip of the hosting formations. These skarns have been interpreted as comprising carbonate-bearing horizons
that were hydrothermally altered and mineralized by fluids ascending from the underlying Sangdong Granite.

From uppermost to
lowermost, the mineralized horizons are termed as Hangingwall, Main, and Footwall horizons, as shown in Figures 7-4 and 7-5 below. The
Footwall and Main horizons have thicknesses that typically range from 1 to 4 m. As well as the main mineralization on these beds, there
are often thin calc-silicate layers developed on the upper and lower contacts of the Main and Footwall horizons.

The Hangingwall horizon
is located near the upper contact of the Myobong shale and varies in thickness from approximately 5.0 to 30.
