Pangea DiamondFields has nineteen exploration and small mine permits in the Kasai Occidental Province of the DRC. Thirteen of these permits are located in the Tshikapa River and Longatshimo River Project Areas, two in the Luebo Project Area and four in the Kasai Project Area.

The Longatshimo River Project comprises six exploitation permits along the Longatshimo River.

History
The Tshikapa Diamond Field is situated within the West Kasai Region of the DRC in the Kasai-Occidental Province, within the Congo-Angola diamond province. The Tshikapa Diamond Field lies directly downstream of the alluvial diamond fields of the Lucapa Graben in northeastern Angola.

Production from the diamond field was dominated by the Belgian company Societe Internationale Forestiere et Miniere du Congo (“Forminiere’) until independence in the early 1960’s. Since then, official records of production are sketchy and unreliable as artisanal miners took control of mining in the area. Historical production from the diamond field was primarily sourced from active rivers and alluvial terraces along the river banks and, to a lesser extent, from the Kwango Formation conglomerates.

Local Geology
The local geology of the Tshikapa area comprises flat Cretaceous sediments un conformably overlying the basement rocks. The Cretaceous sediments are comprised of the Loia and Bukungu Series. The Loia comprises a basal conglomerate dominated with basement clasts followed by arkoses and fine orange-brown sandstones and the Bukungu contains sandstones and local conglomerate. These formations are not diamondiferous. The Loia and Bukungu are overlain by the diamondiferous Kwango Formation. This formation is comprised of a deltaic basal conglomerate succeeded by sandstones. The Kwango Formation is covered by Kalahari Supergroup sands.

Location & Access
The project is located near the town of Tshikapa in southwestern DRC. Tshikapa has an airstrip, which is serviced by five small commercial airline companies and private carriers. In addition a bush airstrip providing access for relatively large freight aircraft has been established within a reasonable distance from the Longatshimo River project and in addition the town of Kamonia lies within 15 km of the camp and is serviced by commercial flights from Kinshasa. Transport by air for smaller items is the most effective, quickest and reliable method of travel within the DRC. The roads in the country are in poor condition and many are impassable. River crossings are often problematic due to the poor state of repair of bridges and ferries.

In order to access both the Tshikapa and Longatshimo River projects, PDF pioneered a 4700km over land route from South Africa through Namibia and Angola into the Southern DRC. This included the replacement or repair of bridges as well as the construction of new sections of road where these were either in disrepair or in some places non-existent.

Infrastructure
PDF set up a permanent camp on the Ikulu project area mid 2007. The camp provides tented accommodation, ablution and mess facilities for 65 staff. Water is obtained from the nearby river and purified for potable purposes. Electricity is provided by a generator. Two 10tpd jigs are also situated on site for processing samples. Access to project areas within the concessions is traversed by motorbike and four wheel drive vehicles as roads are limited. Exploration is ongoing by digging mega pits by hand and using the jigs to process this material.

A major road convoy containing the necessary earthmoving equipment and processing facilities to establish a bulk sampling operation at the Longatshimo River project was dispatched late in August and has recently commenced arriving on site. A plant site has been determined and site preparation has commenced. It is anticipated that the Bulk Sampling operation will be commissioned early in Q1 2008.

Recent Exploration
Exploration commenced in 2005 on the Yusufu and Ikulu licenses, on the Longatshimo River. The aim of the exploration programme was to identify target areas with sufficient gravels to be classified as inferred resources and more specifically to identify follow up targets for the bulk sampling campaign scheduled to commence early in 2008.

The exploration programme included surface mapping and pitting, sampling and processing as well as classification of gravels. This programme is ongoing with the aim of continuing to develop the resource base in the project.

Future Exploration
Exploration is aimed at delineating resources on all licenses throughout 2008. The bulk sampling facility is expected to be commissioned early in 2008 and the short term goal of the programme is to produce a valuation parcel of diamonds to determine the average sales price of diamonds in the resource.
