Helio Reports Excellent Metallurgical Testwork Results From the SMP Gold Project, Tanzania

Gold recoveries up to 96% through conventional processes

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 11, 2008) - Helio Resource Corp. ("Helio" or the "Company") (TSX VENTURE:HRC) is very pleased to report the first metallurgical testwork results from the SMP gold project. Summary results include:

- Optimum circuit responses (% Au recoveries) as follows:

-- 95.6% by Gravity Separation + Gravity Tailing Flotation

-- 95.6% by Whole Ore Flotation

-- 94.5% by Gravity Separation + Gravity Tailing Cyanidation

-- 93.3% by Gravity Separation + Flotation Concentrate Cyanidation

-- 92.5% by Whole Ore Cyanidation

-- 34.7% by Gravity Separation

- Bond ball mill work index of 15 (metric) - "intermediate hardness"

- No preg-robbing activity detected

- Low cyanide consumption

- Tailings should be non-acid generating and free from environmentally deleterious elements

The testwork was undertaken by SGS Lakefield Research Limited ("SGS") in Ontario, Canada on a composite sample from the Kenge target. Tests included head grade analysis, mineralogical evaluation, comminution testwork, gravity separation, flotation, cyanidation (of whole ore, gravity tailing and flotation concentrate) and preliminary environmental testing. Further information and the full results of the metallurgical testwork are available in a report from SGS available on the Company's website at www.helioresource.com.

A 50kg test sample was composited from coarse reject material from mineralised drill core. Material for the test sample was sourced from three previously reported diamond drill holes (SZD011 from Kenge SE Zone, and SZD013 and SZD021 from Kenge Main Zone).

Helio composited the test sample to have a weighted average head grade of 3.05g/t Au on the basis of the previously reported assaying (Company press releases dated March 21, 2007 and May 23, 2007). Particularly encouraging is the fact that screened metallics tests by SGS gave an average head grade for the test sample of 3.6g/t Au - significantly higher than expected.

It is important to note that coarse reject drill core was used, as opposed to fine-grained pulverised material from RC drilling which oxidises rapidly over time and therefore may give unrealistic metallurgical results.

The Company is very encouraged by these metallurgical test results, which support internal petrological, mineralogical and analytical studies indicating that: mineralised material from the Kenge target has a simple mineralogy; gold recoveries by both gravity and conventional flotation / cyanidation processes should be high; and tailing materials should have a limited environmental impact.

Further metallurgical testwork is planned in order to optimise grinding sizes and flotation flowsheet configurations, etc.

The Company currently has three drill rigs at the SMP project, focused on drilling the Kenge and Porcupine targets. A resource statement is expected to be available before the end of the year.


Helio, through its 100% owned subsidiary BAFEX Tanzania Ltd., can earn a 100% interest in four contiguous licences, which cover a 27km strike length of the Saza Shear Zone (see news releases dated December 19, 2005 and September 11, 2006). The project covers the eastern part of the New Saza Gold Mine, which operated between 1939 - 1956, producing approximately 270,000 ounces of gold at an average grade of 7.5g/t Au.

Since June 2006, the Company has drill-tested eleven targets, nine of which are hosted by the Saza Shear Zone. All eleven targets have intersected bedrock-hosted gold mineralisation, the most advanced being the Kenge Target, which has returned up to 22.0m grading 6.9g/t gold in the Main Zone (Company press release dated May 23, 2007). The thickest mineralised intercept at Kenge is from the Mbenge Zone (39.2m @ 2.6g/t Au - Company press release dated March 25, 2008). The thickest mineralised intercept to date at the SMP was drilled at the Porcupine target (52.2m grading 3.3g/t Au - Company press release dated July 21, 2008).
