Koolgarra is a Mineral Exploration and Mining Development company with exclusive rights to explore and develop a 4,000 square kilometre site located in a mineral rich area of Central North Queensland, Australia. 

Koolgarra is conducting an extensive geological examination and assessment of the entire site using airborne and ground based geological survey techniques.  A number os prospecctive Gold and Diamond exploration targets have already been prioritized. 

When a full examination of the project has been completed, Koolgarra will seek additional development capital on the international markets to further develop mining operations of any confirmed base metal discoveries, as well as the proven deposits of silica.

Current Operations

Koolgarra currently has a number of mining lease applications in process. The Lighthouse high purity silica and the Mourilyan high purity silica sand projects are scheduled to be operational in 2009. Koolgarra through its wholly owned subsidiary, Calcifer Industrial Minerals Pty Ltd, has AUSIMM JORC compliant resource estimates for both the Lighthouse and Moruilyan projects. Lighthouse has 1.8 MT of high purity quartz and Mourilyan has 6.8 MT of high purity silica sand.

Location

The Koolgarra tenements are situated 250 kilometres inland from the tropical north coast of Queensland midway in-between Townsville and Cairns.

The site is 38 kms North East of Georgetown, 65kms North West of Mount Surprise, and 75 kms North of Einasleigh. The mineral exploration leases cover a northern portion of the Palaeoproterozoic Georgetown Inlier and are traversed in a north westerly direction by a 25 kms long ancient Paleochannel. The region is underlain by basement rocks some 2000 million years old.

The O’Brien Gemstone Fossicking area is adjacent to Koolgarra and the western edge of the Undara Lava flow traverses the site. 

Previous Exploration Activity

There is a long history of valuable base metal minerals having either been mined or discovered on or near the Koolgarra site by previous mineral exploration companies that have explored this remote area since the 1950’s.

Previously small-scale alluvial mining operations have recovered diamonds, gold, silver, tin, titanium, tungsten, molybdenum, copper, zinc and semi-precious gemstones. Diamonds finds have been regularly reported from the area, as well as sapphires, topaz, garnets, agates and chrysoprase.  Diamond recoveries were mainly recorded during tin mining operations; a simular circumstance to diamond finds in Northern New South Wales.     

Major explorers, notably BHP, Getty Oil and CRA, were seeking immediate large occurrences of minerals using rapid regional survey techniques.  The present Koolgarra operation intends to use more modern methods aimed at locating quality targets that may lead to significant larger finds.  These methods include systematic sampling and mapping of key heavy mineral distributions, including cassiterite, titanium group minerals, zircon, garnets and gem minerals.

Most of the previous small-scale mining operations were restricted to alluvials across the northern area of the tenements. The southern areas expose a major felsic volcanic complex some 250 million years old, which is very poorly known; this we are calling the Mount Direction Complex. The Queensland Government Department of Mines and Energy (DME) records show that little if any mineral exploration has been conducted across these areas.  Elevated signatures for Uranium and Thorium were recorded by Mega Uranium across the western part of the volcanic complex and these will be further investigated.
