Caldera Resources Inc

Gold - Diamond - PGM projects in Australia & Albania.

Caldera Resources Profile

Caldera Resources Inc, Montreal, Quebec, TSX.V : CDR, The principal aim of the Company is to discover an economic mineral deposit. This is being pursued through “grassroots” and advanced stage exploration activities at eight diamond projects in Western Australia. The Company is also engaged in gold/ base and precious metal exploration in Western and South Australia.

The Company’s diamond projects include two advanced stage projects, namely the Ellendale East and South Projects and the Runton Project, and five “grassroots” stage projects. Promising gold mineralization has been found in the Cromer Cone project which will be further explored.

The Mt. Carulina project is located at the north-east margin of the Gawler Craton in South Australia and this property is being explored for iron oxide, copper-gold mineralization.

The Abminga Project is considered to have potential for uranium, nickel and/or platinum group metal mineralization.


Canbiomine Resources is a wholly owned subsidiary of Caldera Resources. Canbiomine division focuses on developing bioleaching projects in Southeastern Europe, namely Albania and Serbia.

Canbiomine is developing the Gjegjan Copper Project, with the goal to produce over 20,000 tonnes of copper cathode by using bioleaching process with its partner BacTech Mining Inc (BM:tsx-v).


Caldera Resources Inc. has been exploring for diamonds in Australia for several years. Caldera has 1 property of merit and 2 advanced diamond exploration projects.


Mt. Sarah and Mt. Narlee

The Mt. Sarah and Mt. Narlee Basemetal Projects are located approximately 75 kilometres northwest of the town of Oodnadatta in northern South Australia and with a further Exploration Licence being made in January 207, now comprises of two Exploration Licences.

Mt. Carulina

The Mt. Carulina Gold/Basemetal Project is located in northern South Australia. The Mt. Carulina tenement is held by the Corporation through Caldera Resources Pty Ltd. as to 75% and Ellendale as to 25%.

Gjegjan Copper Project, Albania JV with ECHO-T shpk, Albania

The historic Gjegjan mine produced 5Mt of 3% Cu. A published exploited resource estimate quotes 6Mt at 3.51% Cu, 0.9% Zn and 0.07% Co. The Mine opened in 1961 and closed in 1993, and involved both underground and open pit mining. Historical records indicate that the cut off grade for mining was 1% and a smelter cutoff of 2.5% The geology is described as massive pyrite with silica and chalcopyrite.

ECHO-T performed a successful bioleach study at The Institute of Environmental Geology and Geoengineering in Rome, Italy in 2003. ECHO-T had taken sample in 2003 and was evaluated at 0.30% copper. (not 43-101 compliant)

CanBiomine hired GWP Consultants to prepare an initial 43-101 compliant report and make recommendation for a scope study to be implemented in spring 2009. Initial site visit was completed on September 20, 2008. A final report will be available in early December.


Bioleaching is the extraction of specific metals from sulphide minerals and refractory ores through the use of bacteria. Bioleaching technology used by Caldera has been successfully deployed by BacTech to extract gold and copper.

BacTech's technology takes bacteria cultured from the environment and applies them in a way that speeds up the natural process of sulphide degradation by up to 500,000 times. There is no "re-engineering" or manipulation of these natural bacteria, but BacTech uses its' knowledge and experience of how to isolate and apply the bacteria, and create the perfect environment for them to operate effectively. This converts a slow natural process into a commercial economic process for metal extraction, while protecting the environment by not using the alternative techniques such as roasting. The only byproduct of bioleaching is an inert iron or iron arsenate precipitate, which is environmentally benign.

The front-end of the technology can take low quality concentrates and process them through bioleach reactors to produce metals. Precious metals typical are removed from solids, and other metals such as copper reside in a liquor which can then be recovered through Eletrowinning process.
