Dr. Wayne Taylor has reported that chrome spinels which have been recovered from two previously untested depth intervals, 64-66m and 71-72m, of drill-hole R2-2, are of high interest and their compositions resemble kimberlitic spinels. This opinion confirms the findings of Caldera's consultant, Martin Jackson, who also considers the previously reported chrome spinels to be of high interest, the majority of which are indicative of a diamond stability field source. Additional chrome spinels have also been recovered from a composite sample collected from 46-90m in the same drill hole. A pyroxene pyroxene (pī`rŏksēn), name given to members of a group of widely distributed rock minerals called metasilicates in which magnesium, iron, and calcium, often with aluminum, sodium, lithium, manganese, or zinc occur as X in the chemical with an inclusion of perovskite Perovskite (calcium titanium oxide, CaTiO3) is a relatively rare mineral on the Earth's crust. Perovskite crystallizes in the orthorhombic (pseudocubic) crystal system. , a mineral commonly found in kimberlites and some lamproites, has been recovered from 64-66m. During November and December 2004, the Company reported the recovery of one pale yellow micro-diamond from a 4.4 kg caustic fusion sample obtained from 88-90m, and high interest chrome spinels from 46-48m and 88-90m, in drill-hole R2-2. The chrome spinel spinel, magnesium aluminum oxide, MgAl2O4, a mineral crystallizing in the isometric system, usually as octahedrons. It occurs as an accessory mineral in basic igneous rocks, in aluminum-rich metamorphic rocks, and in contact-metamorphosed chemistry suggests that the majority have been sourced from the diamond stability field. Modeling of 200m line-spaced aeromagnetic data by Barrett Geophysical Exploration Consultants indicates a minimum depth extent of 600 metres and almost vertical inclination for the anomaly drilled. Hole R2-2 was completed to a depth of 91 metres and the Company plans to complete a deeper drill program during 2005 to intersect fresher material. The drill material recovered at 91 metres is too fine for petrological identification. The intersection of "fine-grained" material from which abundant chemically high interest chrome spinels and micro-diamond have been recovered, suggests the possible presence of crater facies facies /fa·ci·es/ (fa´she-ez) pl. fa´cies [L.] 1. the face. 2. surface; the outer aspect of a body part or organ. 3. expression (1). material forming part of a large and deep intrusive complex.

The caustic fusion sample was processed by Striker Resources' laboratory in Perth. Caldera continues to investigate the merits of joint-venturing this project, which covers an area of 200 square kilometres, or to retain 100% project ownership.

A further three Exploration Licence's covering 600 square kilometres, which adjoin the Runton Project to the south, will be incorporated into the Cromer Cone Project to give a project area of 1,750 square kilometres. A 100 metre infill airborne magnetic survey will be completed in the second quarter of 2005 over areas identified from the 400 metre line-spaced aeromagnetic survey of 2004 as having potential to contain kimberlite kimberlite: see diamond. kimberlite or blue ground Dark, heavy, often fragmented igneous rock that may contain diamonds in the rock matrix. or lamproite intrusives. This high resolution survey will provide the necessary definition of magnetic anomalies to complete a sampling program, and subject to positive results, a drill program.

The recovery of diamond and abundant spinels of interpreted diamond association from drilling at Runton, suggests the broader region to be highly prospective for kimberlites and lamproites.

Caldera is engaged in diamond exploration in Australia through five projects. Two projects are located in the Pilbara region of northern Western Australia, one of which is joint ventured with Mr. Ronald Winston of Harry Winston Inc. The Company also has two projects located adjacent to the Ellendale Lamproite Field in the Kimberley region of Western Australia. Both of these projects are also joint ventured under separate arrangements with Mr. Ronald Winston. One project is located on the Yilgarn Craton of Western Australia which is joint ventured with SouthernEra Diamonds Inc. (TSX:SDM SDM - Schematic Data Model ). Caldera also has four base metal/gold projects in South Australia. One of these projects is the Mt. Carulina Project which is an Olympic Dam - style base metal/gold target.
