Randsburg's Titan Iron-Titanium-Vanadium Project Produces 95 Percent Titanium Dioxide With Altairnano Hydrochloride Process

TORONTO -- (MARKET WIRE) -- August 31, 2005 -- Randsburg International Gold Corporation (TSX-V: RGZ) announced today the results of hydrometallurgical test work on Randsburg's Titan Project indicating that its magnetite/ilmenite material is well-matched to the Altair Nanotechnologies, Inc. (NASDAQ: ALTI) Altairnano Hydrochloride Pigment (AHP) process. Greater than 95% titanium extractions were observed in two bench scale tests making this one of the AHP process' best performing samples.

Randsburg contracted Altair Nanotechnologies (Altairnano) in May 2005 to perform AHP tests on Titan material to evaluate the potential for added value production of titanium dioxide pigment. Two drill hole intervals comprising 20 metres (66 feet) each were selected for in-depth chemical and mineralogical testing in Altairnano's mini-AHP reactor circuit. The two intervals were from vertical drill hole RA-6-04 drilled in 2004 to a total depth of 387 metres (1270 feet.) RA-6-04 was continuously mineralized from surface and the hole ended in mineralization. RA-6-04 is located near the centre of the Titan mineralization.

RA-6-04 drill intercept 155.85-173.85 metres, assaying an average 17.65% titanium dioxide and 40.11% iron, and RA-6-04 drill intercept 259.85-279.85 metres, assaying an average 18.90% titanium dioxide and 39.50% iron, were selected for testing. The material Altairnano received was ALS Chemex's assay rejects from which ALS Chemex cut a small split to determine the assays listed above. Altairnano received a total of 72.74kg (upper drill intercept (equal sign) 34.99kg, lower drill intercept (equal sign) 37.75kg) in late May.

Work Completed

Each sample, representing a 2 meter drill interval, was weighed and then screened at 35 mesh (500 (micro)). The oversize was cone crushed so that all material passed a 35 mesh (500 (micro)) screen. Saved as uncrushed are 5.67kg of 14 x 35 mesh (1397 x500 (micro)) and 3kg of 14 (1397 (micro)) mesh.

All material passing 35 mesh (60.13kg) was combined and mixed on a large plastic sheet. A representative 1kg sample was cut from the sample cone and analyzed by Inductively Coupled Plasma (ICP). The 1kg sample was cone and quartered to yield a 250g sample for size analysis, with each fraction analyzed by ICP.

Next, a 500g sample was cut for treatment by magnetic separation. This sample was first wet screened at 270 mesh (53 (micro)) to produce a 35 x 270 (500 x 53 (micro)) mesh sample; the -270 mesh "slimes" were discarded. Thin sections for petrographic examination were prepared from the "feed" ALS Chemex rejects. Various grains were then imaged by Scanning Electron Microscope and Energy Dispersive X-ray (EDX).

A 450g sample of the less than 35 mesh material was treated in a reactor vessel and subjected to the proprietary Altairnano process.


Sample RA-6-04, consisting of material from the two drill intercepts noted above, contains about 70% magnetite with intergrown ilmenite and about 30% gangue minerals, largely olivine, pyroxenes, minor plagioclase. Ilmenite intergrowths amount to about 10-15%. Percentages represent volume estimates.

EDX imaging nicely displays the character of the magnetite-ilmenite intergrowths that typify the Titan samples. Ilmenite is present within magnetite grains as discrete, angular grains less than 100 (micro) across (commonly less than 50 (micro)) as well as exsolving as acicular boxwork ribs only a few microns thick.

Preliminary analytical results show that more than 95% of the titanium, including both the ilmenite grains and the titanium associated with the magnetite was recovered.

At this time, Randsburg and Altairnano are performing additional testing and evaluations in order to fully determine the scope of the suitability of the AHP process for the Titan material. There can be no assurance that additional testing will achieve positive results or that Randsburg will utilize the AHP process in the future.


Altairnano's AHP process is the first new titanium dioxide pigment manufacturing process to be developed in the last fifty years. The AHP process extracts titanium and manufactures titanium dioxide pigment from low-cost, titanium-rich material. The process offers an environmentally friendly manufacturing process featuring a cost structure substantially lower than existing supply methods, not including disposal and handling costs of hazardous wastes associated with competing production processes.

Earlier this year, Altairnano Bateman Titania was formed through a joint venture between Altairnano and Bateman Engineering BV. Altairnano Bateman Titania brings together Altairnano's proprietary and patented AHP process with Bateman's engineering expertise to develop, design, construct, commission and operate manufacturing plants to produce titanium dioxide pigment. Titanium dioxide pigment, currently a $9 billion industry worldwide, is used in a variety of applications including the manufacture of paint, plastics and paper.

The AHP process is a disruptive technology because it threatens the titanium dioxide pigment supply chain established over the last 50 years. The Altairnano process is economic for plants producing 30,000 tons a year to large-scale manufacturing exceeding 100,000 tons per year. This is an important capability in emerging economies and to specialist pigment producers as it enables these smaller companies with limited capital resources to affordably enter the market. These plants can be readily expanded to larger scale manufacturing operations as customer demands grow.

The Titan Project

Randsburg's Titan Project is an iron-titanium-vanadium advanced exploration project covering 5370 acres, situated 350 kilometres north of Toronto, Ontario, Canada. Titan Iron Mines Ltd. reported iron-titanium reserves of 141 million tons from previous drilling, trenching, geology and geophysics in the 1940s, 1950s and 1960s in this area.

A. S. Bayne, P. Eng. (1967) submitted the "Report on Potential Feasibility of Titan Iron Mines Limited, Angus and Flett Townships, Ontario." In this report, Bayne estimated that the iron-titanium deposit contained an indicated and inferred 141,000,000 tons of reserves grading 35.58% iron and 15.64% titanium dioxide within an area of 1,400 by 900 feet and to a depth of 1000 feet. The report is part of Randsburg's files on the Titan deposit. The estimate is based upon:

       1) The drill logs and assays for iron and titanium from 1,795 feet
          of diamond drilling in 11 holes completed in 1947. Drilling was
          confined to an area in the northwest portion of the mineralized
          body. The drill logs and assays are in Randsburg's files.
          Assaying was done at Swastika Laboratories.

       2) 119 samples assayed for iron and titanium from 2,100 feet of
          trenching completed during the 1940s. The extensive trenching was
          completed over that part of the mineralized body located above
          low-lying, wet areas. Assay certificates from Timiskaming Assay
          Labs are in Randsburg's files.

       3) Personnel of the Ontario Department of Mines carried out
          additional sampling and assaying. The results from this work are
          comparable to those of Titan Iron Mines as discussed above. This
          information is in Randsburg's files.

       4) Vertical interpolations using the areas within the 10,000, 10,500
          and 11,000 gamma contours from a Lockwood Survey Corporation
          Limited airborne survey flown in 1966. The survey map is in
          Randsburg's files.
The Company believes that the above information lends credence to the reported historical tonnage for the Titan deposit.

This reserve figure was calculated prior to the implementation of NI 43-101 standard. The categorization of reserves at that time would be equivalent today to a mineral resource under current 43-101 standards as defined by the Canadian Institute of Mining, Definition Standards On Mineral Resources and Mineral Reserves adopted November 14, 2004.

The Company is not relying on these reserve figures as 43-101 defined resources or reserves verified by a Qualified Person and investors are cautioned that recent independent verification of the reserve data has not been performed and Randsburg has not completed sufficient exploration on this part of the property to verify the classification of the historical figures as a resource or reserve.

Randsburg is currently conducting Phase II of a Stage 2 drill program which includes drilling outside of the area where the historical reserve calculations were originally obtained. The Company has drilled and reported assays from a total of 12 drill holes on the Titan project. Please refer to the Company's website at for past news releases indicating drill hole locations, intersection length, and assay composition of the material from these drill holes. The target is open along strike and depth. If the drill program is successful, Randsburg will, if warranted, define a resource estimate.

The Titan Project is being conducted under the supervision of Ken Germundson, Ph.D, Professional Geologist, the Company's Qualified Person under the meaning of National Instrument 43-101. The drill logs, cores and assay results have been reviewed and verified by Dr. Germundson. Dr. Germundson has reviewed and approved the contents of this news release.
