ASX ANNOUNCEMENT
5 October 2011
STRONG DRILL RESULTS SUPPORT OPEN PIT DEVELOPMENT STRATEGY
-
Focus delivers high-grade drill results at two open pit targets at the Tindals Mining Centre
-
Establishes maiden Mineral Resource at targets and identifies potential for future open pit development
-
Drill results at the two targets deliver intersections including:
-
5m @ 26.3g/t Au
-
2m @ 25.7g/t Au
-
16m @ 2.7g/t Au
-
12m @ 3.9g/t Au
Australian gold producer Focus Minerals (ASX: FML) has delivered a strong set of drilling results and posted a maiden Mineral Resource at two surface targets at the Tindals Mining Centre in Coolgardie, supporting its strategy to deliver a sustainable 25-30,000 ounce per annum production from the operation for the next 5 years.
Drilling at the Undaunted and Lady Charlotte targets, both located at the Tindals Mining Centre, has delivered a series of high-grade intercepts including: 5m @ 26.3g/t, 2m @ 25.7g/t, 16m @ 2.7g/t, and 12m @ 3.9g/t (see Figure 1 & Appendix 1).
A 150 metre mineralised strike length has now been outlined at Undaunted and the deposit remains open at depth, with tightly folded mineralised diorites in the area showing strong similarities to Focus’ Countess underground operation nearby.
Focus is also pleased to announce that it has established a maiden combined JORC reportable Mineral Resource of 130,000t @ 2.0g/t for 8,250 ounces at Undaunted and 103,000t @ 2.0g/t for 6,500 ounces at Lady Charlotte (see Table 1).
Focus Minerals Chief Executive Campbell Baird said the high-grade intersections and delivery of a maiden resource supported the significant mine life potential for new open pit operations (Figure 2).
“This work has clearly shown the extraordinary gold endowment in the Coolgardie region and the success that comes with a dedication to exploration,” said Mr Baird.
“Over the last six months or so we have brought three pits into production and developed a number of targets into significant projects.
“These results indicate promise for ongoing open pit development in accordance with our surface growth strategy.”

Drilling at Undaunted targeted previous intercepts from earlier in the year (see ASX release dated 01/03/11) and has identified a mineralised diorite with a strike length of 150m returning significant intercepts including: 16m @ 2.7g/t, 6m @ 4.5g/t and 6m @ 3.1g/t. The program also targeted an area to the south of Undaunted around old workings with multiple significant intercepts including 6m @ 3.8g/t and 3m @ 4.5g/t. The drilling has to date only targeted a depth of 40m and Focus will soon be targeting further results at depth.
Drilling at Lady Charlotte (immediately to the east of Undaunted) has targeted interpreted diorites around some historical intercepts. This has returned a number of high-grade intercepts including: 5m @ 26.3g/t, 2m @ 25.7g/t and 12m @ 3.9g/t. This is the first time Focus has undertaken RC drilling in this location, and highlights the potential in the area.

BACKGROUND INFORMATION – FOCUS MINERALS LTD
Focus Minerals is an expanding gold producer based in Western Australia’s Eastern Goldfields. The company holds the mineral rights to 449km[2] of tenements and is the largest landholder in the Coolgardie Gold Belt, 35km west of the ‘Super Pit’ in Kalgoorlie. Focus is currently in production from underground and open pit operations at its flagship Tindals Mining Centre in Coolgardie, adjacent to its 1.2Mtpa Three Mile Hill processing plant. It also recently opened a new high-grade underground mine 85km south of the plant, The Mount. Focus has an 80% shareholding interest in Crescent Gold Limited which owns the Laverton Gold Project, located 250km northeast of Kalgoorlie in Western Australia.

Note to accompany Drill Results Table
RC holes are sampled to 1m intervals. All samples are assayed using a 400 gram Pulverize and Leach (PAL) system at Focus’ on Site assay laboratory. All mineralised intersections are then sent to Amdel to be assayed with the 40 gram fire assay method. All mineralised intersections are quoted as down-hole lengths with uncut gold values. The true thickness is approximately 65% of the down-hole length. Gold grades are reported at a nominal cut-off grade of 1g/t Au. NSR = “no significant result” (above 1g/t).
Notes to accompany the Mineralised Resource Statement
The Undaunted and Lady Charlotte deposits are hosted within tightly folded silica altered (“bleached”) diorite intrusions within an ultramafic sequence. The lodes vary in width from 2-10m. While most of the resource defined so far is in the oxide weathering zone, some quartz-sulphide micro-veins have been logged with associated pyrrhotite in the transitional weathering zone. Silica alteration is also evident. The geology seen in the Undaunted and Lady Charlotte area would suggest that the mineralisation style is similar to other diorite hosted deposits in the Tindals Mining Centre. No visible gold has been seen.
The resource is a result of drilling done during 2011 by Focus and pre-Focus drilling. The updated interpretations were then used to create a new resource model for the deposits.
Drilling Information
The Undaunted / Lady Charlotte area has been drilled with a total of 227 RC drill holes for a total of 11,959m. Historical mining has been undertaken in the area in the form of old historic shafts and minor stoping from these. Drill spacing is generally 20m x 20m in the resource areas.
The drill holes completed in the area are mostly shallow (no greater than 48m depth) and deviation is assumed to be minimal. A few historic deeper holes drilled at Lady Charlotte were down hole surveyed with EMS. All recent drill holes were surveyed in GDA94. All drilling has been logged (lithology, alteration, veining and mineralisation) in detail and stored in electronic databases after being validated.
Most samples (Focus and pre-Focus drilling) have been assayed using the Fire Assay method at ALS Chemex or Kalgoorlie Assay Laboratory in Kalgoorlie. For drilling since 2005 a 30g Fire Assay with AAS finish was used at ALS Chemex, while a 40g Fire Assay with ICP-MS finish method at the Kalgoorlie Assay Laboratories. The remaining samples (approximately 20%) were assayed by Leachwell method at the Three Mile Hill on site laboratory. The Leachwell method is generally used as a first pass assaying method, with all intercepts then sent for Fire Assay. In this case however, the residues were destroyed and the follow-up Fire Assay on the samples was therefore not carried out. Any areas with Leachwell results were classified as Inferred Mineral Resource.
Geological Model
The geological interpretation (geology and mineralisation) and the resource estimation were conducted internally. The mineralised interpretation was digitised to either geological boundaries or a nominal 0.5g/t cut-off grade where the geological contact was obscure. No mining dilution has been incorporated into the resource interpretation, although some low grade zones (<0.5g/t) have been included to allow for continuity of the interpretation. The interpretation was extrapolated either 20m past the last drill hole, or half way to the next drill hole closing off the mineralisation (which ever was the smallest distance).
Samples within individual wireframes were composited to 1m intervals. The composites were used to determine the necessary top cuts, which were done by a combination of Skree Plots and cumulative frequency plot analysis. The top cut value applied to Undaunted was 8.5g/t Au, with a 10g/t Au top cut applied to Lady Charlotte.
A Surpac block model was created in GDA grid co-ordinates. The estimation was completed using the Ordinary Kriging (OK) method.
A bulk density of 1.8t/m[3] was applied to the oxide material and 2.4t/m[3] to the transitional material in the model. No fresh material exists within the model due to the shallow drilling conducted. The density values applied are the typical values for oxide and transitional material in the Coolgardie region.
The reported grades, tonnages and contained ounces are rounded to appropriate levels of precision in accordance with the recommendations of the JORC Code. The Mineral Resource has been reported at a 1g/t lower cut-off grade and is depleted by using the known historical void pickups in the area.
