Summary:
The Jinlonggou gold deposit lies within a low, north-west trending, mountain range (Tanjianshan) composed of Wandonggou and Tanjianshan Group rocks, with Early Palaeozoic gabbro intruding the Proterozoic rocks and Late Paleozoic porphyritic plagiogranite intruding all older units.
The Jinlonggou gold mineralization lies within Member 1 of Formation B of the Wandonggou Group. The host rock sequence is dominated by carbonaceous phyllites that commonly contain porphyroblastic chiastolite. The rocks are dark grey to black and display a well-developed foliation. In the central and southern parts of Jinlonggou, a number of orange brown sandstone bands are also present and act as key marker horizons.
Two intrusive rock types occur within the limits of the mineralization and are both of probable intermediate composition. The dominant intrusive is a fine grained phyllic altered diorite that is either light orange or light green in colour. The intensity of alteration has been used to sub-divide the diorites into three classes – D1, D2, and D3. Diorites where original textures are still visible are classified as D1, where partly obscured, D2 and where completely altered, D3. In some specimens earlier silicification has preserved some of the euhedral plagioclase phenocrysts. Acicular amphiboles (actinolite) are visible in D1 samples. The diorites have been further altered in areas of mineralization.
The second intrusive type is quartz-feldspar porphyry ( ........
Summary:
All ore and waste will be mined via conventional, open pit mining methods, using mining contractors. The operation is planned to utilize selective mining techniques to separate ore and waste. The mining equipment that is considered to be suitable for the TJS would include 20 tonnes to 75 tonnes back hoe excavators for ore zone mining and offhighway haul trucks with a payload capacity of between 10 to 50 tonnes.
