Mining in Cambodia
Indochine recently transferred their Cambodian projects, which were owned by Indochine Resources pre IPO, to an alternative company, Capital Mining (AS:CMY). As from 2014 Capital Mining is solely responsible for exploration development of the Ratanakiri project.
The Ratanakiri Project lies in the remote far north-east of the country. Similar intrusive centres have been mapped here as well as older metamorphosed rocks exposed along the Laos and Vietnamese borders. Alluvial gold workings and favourable host rocks for large tonnage deposits make this area very prospective for delineating economic occurrences.
Subsequent to securing tenure on these projects exploration commenced in 2007. Indochine has built up a solid exploration base, beginning with the acquisition of high definition satellite imagery, and the completion of an airborne magnetic and radiometric survey.
Regional scale structural, geological and alteration interpretations identified initial high priority targets for follow-up exploration. Field based exploration activities have followed including mapping, geochemical sampling of streams and soils, and diamond drilling.
Cambodian Regional Geology
Most of Cambodia is part of a stable, continental tectonic plate known as the Kontum Massif that is mostly covered by a sequence of Triassic-Jurassic sandstones and siltstones of the Khorat Basin. These sediments are primarily terrestrial in origin and contain extensive bedded non-fossiliferous sediments. The Permo-Carboniferous Truongson and Loei Fold Belts bound the Kontum Massif to the north and west respectively. These fold belts contain arc type volcano-sedimentary sequences including andesitic volcanics and limestones.
The Kontum Massif and the Khorat Basin sediments have been intruded by a suite of small to medium sized dioritic to granitic plugs. The range of composition suggests a fractionating magma source. Most of the intrusives have large irregular hornfels halos indicating that the roof zones of the plugs are only partially exposed. Several hornfels areas without apparent intrusives indicate the presence of plugs at a shallow depth below the current erosion surface. This is an ideal environment for the development of intrusion related gold deposits.
The Ratanakiri Project area in the north is an older and more deeply eroded zone of typically Permo-Triassic meta-sediments, volcanics and intrusives. This is bounded by younger Jurassic and Tertiary terrestrial and near shore sediments. It forms a high standing mountainous block on the Cambodian - Laos - Vietnamese borders. The northern part of this older block is sutured to the north and south on to a block of Jurassic sediments.
The Ratanakiri Project comprises fourteen (14) licences covering an area of 2,900km2 (Table 2). The first 12 of these Licenses listed in the table below are held by IRL (Table 2). The Company has also recently entered into an Agreement with Ratanakiri Consulting Company Pte Ltd as they are the Licence holder of the two (2) Licences.
