See ITU-R BT. ) is pleased to announce the results of the Runton aircore drill program totalling 371 metres carried out in September 2005 on the 100% owned Runton Project which covers 200 square kilometres. Results have been delayed due to difficulties in interpreting rock types and establishing the possible sequence of geological events at the Runton Project area. The technical staff and consultants are encouraged and surprised at the diversity of rock types encountered to date. For shareholder assistance, an aeromagnetic image of the project will be posted on the Company's website to show the extent and nature of the intrusions within the project area. The following are the key targets of interest. - Northern Dyke - additional high interest chrome spinels recovered from overlying overlying suffocation of piglets by the sow. The piglets may be weak from illness or malnutrition, the sow may be clumsy or ill, the pen may be inadequate in size or poorly designed so that piglets cannot escape. tuffaceous rocks verify results from the 2004 drill program and confirm the size extent of the intrusion and the associated tuffaceous rocks. - Southern Dyke - an extremely weathered ultrabasic ul·tra·ba·sic adj. Containing magnesium and iron and only a very small amount of silica. Used of igneous rock. ultrabasic Containing magnesium and iron and only a very small amount of silica. rock identified along with the recovery of chrome spinels and high interest clinopyroxenes have been recovered. The mineral chemistry of these clinopyroxenes indicates a probable kimberlite/lamproite source. This discovery of ultrabasic rock represents a major break through for the project. - Centre Anomaly - evidence of extensive carbonate mineralisation in the overlying tuffaceous rocks. These zones, rich in carbonate, contain numerous micron-sized grains of gold, chalcopyrite, galena galena (gəlē`nə) or lead glance, lustrous, blue-gray mineral crystallizing usually in cubes, sometimes in octahedrons. It is the most important ore and the principal source of lead. , sphalerite sphalerite (sfăl`ərīt, sfā`–), mineral composed of zinc sulfide, usually containing some iron and a little cadmium. It occurs in crystals of the isometric system but more generally in cleavable, compact masses. and zinc oxide zinc oxide, chemical compound, ZnO, that is nearly insoluble in water but soluble in acids or alkalies. It occurs as white hexagonal crystals or a white powder commonly known as zinc white. identified in drill chips. The interpretation of this mineral assemblage indicates an underlying heat source and possibly the presence of a base metal deposit with gold credits. Northern Dyke The Northern Dyke is located on the northern limb of a regional syncline in folded Proterozoic sedimentary rocks (Geol.) See See also: Sedimentary . Geophysical modelling of this close line-spaced aeromagnetic anomaly indicates that it is a dyke which is approximately 8 km long and up to 300m wide and models with extensive depth extent. A single drill hole in the centre of the anomaly during the 2004 drill program identified tuffaceous rocks containing numerous diamond associated chrome spinels and one faint yellow micro-diamond was recovered. A drill hole, 103 metres, positioned on the eastern end of the Northern Dyke during the 2005 drill program has identified further tuffaceous deposits carrying chrome spinels that show a more diverse grouping compared with the first drill hole. Some of these chrome spinels also plot in the diamond stability field. Twenty two microdiamonds have been previously recovered from 6.4 kilograms of surface tuffaceous rocks. Minor and trace element ratio analysis of these tuffaceous rocks indicate a probable kimberlite/lamproite affinity. Southern Dyke The Southern Dyke was identified by airborne geophysics and lays along the axial plane of a large syncline of Proterozoic sedimentary rocks plunging shallowly to the east. Two drill holes were sited on this feature, one of which intersected 30 metres of extremely weathered ultrabasic rock commencing from near surface. Petrological work carried out by Dr. G. Pooley on this material shows a very weathered ultrabasic saprolite sap·ro·lite n. Soft, partially decomposed rock rich in clay and remaining in its original place. saprolite with an ex-olivine texture. Indicator minerals recovered include abundant chrome spinels and high interest clinopyroxenes. Geophysical modelling of the close line-spaced aeromagnetic anomaly indicates that it is an intrusive dyke that is 10 kilometres long and up to 65 metres wide with substantial depth extent. Due to very limited sample recovery, further drilling of this target to recover fresh material is of high priority. This drill intersection is of significant interest and adds to the expanding knowledge of the amount of geological activity that this locality has undergone. Minor and trace element ratio analysis of the ultramafic ul·tra·maf·ic adj. Ultrabasic. ultramafic Containing mainly mafic minerals. Used of igneous rocks and often used interchangeably with ultrabasic. Dunite is an ultramafic rock. and associated tuffaceous rocks indicate that they are possibly related to the kimberlite/lamproite family. Centre Anomaly This ovoid o·void or o·voi·dal n. Something that is shaped like an egg. adj. Shaped like an egg; oviform. ovoid having the oval shape of an egg. ovoid body colloid body. magnetic feature lies 3 km to the south of the Northern Dyke and measures approximately 3 km long by approximately 500 metres wide. Geophysical modelling of this close line-spaced aeromagnetic data indicates that this anomaly is an intrusive with substantial depth extent. Two north-northeasterly trending dolerite dol·er·ite n. Chiefly British A dark, fine-grained igneous rock; diabase. [French dolérite, from Greek doleros, deceitful (from its easily being mistaken for diorite) dykes are situated on the eastern side of the anomaly and are likely to be mantle tapping conduits of regional significance having the potential to have been active several times in their history. They appear to be responsible for the variety of intrusives and mineralisation in the immediate vicinity. A single drill hole was located at this target and reached a depth of 139 metres, which was approximately 60 metres short of the target depth. Due to ground conditions, the drill rig did not have the capability to go beyond this depth without jeopardizing the drill hole. Work completed on samples from this drill hole has shown pervasive carbonates with some material containing up to 60% calcite calcite (kăl`sīt), very widely distributed mineral, commonly white or colorless, but appearing in a great variety of colors owing to impurities. . The occurrence and frequency of variably sized veins of carbonate appears to increase with depth. These carbonate bearing veins and rocks also contain many micron-sized particles of gold, chalcopyrite, galena, sphalerite and zinc oxide which were identified on the scanning electron microscope scan·ning electron microscope n.

Ellendale East Project - Kimberley Region - Western Australia During June 2005, an aircore drill program identified volcanoclastic quartz tuff material at seven drill holes resulting in the identification of five new lamproite intrusions. The Ellendale East Project is located 25 kilometres southeast of the operating Ellendale 4 Pipe Mine owned by Kimberley Diamond Company N.L. Mr. Ronald Winston who has the right to farm-in arrangement on Ellendale East may elect to earn a 50% interest in the project by reimbursing the Company A$400,000 and expending A$3Million on further development exploration over 2 years. Mr. Winston may then earn an additional 10% interest by paying Caldera A$1M and expending A$7M over the next three years. A delay in results has occurred due to the large volume of material that required processing and that the various laboratory facilities carrying out this work have been extremely busy. Laboratory processing and associated work is near completion which will enable the Company to make a statement regarding three results and also provide a full report to Mr. Ronald Winston. Mr. Winston will have 30 days as to his election to proceed with the farm-in arrangement. Other Activities. 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, one of which is also joint ventured with Mr. Ronald Winston. One project is located on the Yilgarn Craton of Western Australia which is joint ventured with SouthernEra Diamonds Inc. (SDM SDM - Schematic Data Model :TSX). The SouthernEra tenements also include a joint venture with BHP Billiton Limited on a nickel/platinum project. Caldera also has three 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.
