Cluff Gold Announces a 40% Increase in Total Mineral Resources at the
Baomahun Gold Project, its Flagship Gold Deposit in Sierra Leone
- Inferred Mineral Resources have increased by over 500,000 ounces to 957,000 ounces of gold (9.2 million tonnes grading 3.2 g/t Au). - In addition, total Measured and Indicated Mineral Resources are now 1,103,000 ounces of gold (12.0 million tonnes grading 2.9g/t Au). - A Scoping Study has been initiated into the combined open pit/underground scenario with completion expected in Q1, 2010 which will be independently reviewed by SRK Consulting (UK) Limited. - A work programme to follow up on the positive results announced today is planned to commence in Q4 2009. This will include investigation of potential extensions of the mineralisation as announced on 8 September 2009, including DDH301 (10 metres at 10.5 g/t) in the Central Zone and DDH298 (9 metres at 5.97 g/t) in the Eastern Zone.
Commenting on these results,
The increase in the Mineral Resource at Baomahun results from the completion of an additional 7,000 metres of core drilling across 11 holes that has been completed since the previous Baomahun mineral resource was announced on
Table 1 below summarises the current Mineral Resource estimate at Baomahun and is based on a 1g/t Au cut off:

The mineral resources estimates were carried out by Andrew Owusu Asante who is a Member of Australasian Institute of Mining and Metallurgy (AusIMM) under the direction of Douglas D Chikohora, MSc, MIMMM, CEng., Technical Director and Cluff Gold's Qualified Person who has reviewed this news release for accuracy and compliance.

Gold grades were estimated using ordinary kriging and inverse distance weighting interpolation methods. The mineralisation models were constrained within the wireframe with primary block dimensions of 10 metres along the strike and cross structure directions, and 10 metres in the vertical direction. Higher-grade values have been statistically capped to 40 g/t Au. A total of 3,346 density determinations have been undertaken using the displacement method and the density samples falling within each defined wireframe domains were selected and the average density applied. Tonnages and grades are reported using a 1.0 g/t Au cut-off.
Drill cores used for assaying were sampled at a maximum of one metre intervals and were cut with a diamond saw with one half of the core placed in sealed bags and sent to the
Metallurgical testwork, which included recovery and comminution tests, has now been completed to feasibility stage level. Results obtained from these tests have confirmed preliminary earlier findings that high gold recoveries can be achieved using a conventional direct cyanidation processing method. Comminution test results show that the mineralised material at Baomahun requires conventional milling with only medium energy requirements.

About Cluff Gold
Cluff Gold is focused on the identification, acquisition and development of gold deposits in West
Baomahun,
The Baomahun Gold Project covers an area of about 137 km2 and is located about 180 kilometres east of
The Baomahun exploitation permit covers more than 12 kilometres of prospective strike along the Kangari Hills which is composed of Archaean greenstone belt terrain consisting of banded iron formation (BIF). Gold mineralisation in the drilled areas is intimately associated with the BIF and other lithologies in close proximity to the BIF. Accordingly, future exploration and drilling will continue to use the BIF as a marker horizon for auriferous zones along the belt.

Cluff Gold now holds 100 per cent. of the Baomahun Gold Project. Cluff Gold announced on
