ASX ANNOUNCEMENT
30 July 2014
Focus Confirms Strong Results from Coolgardie and Laverton Exploration Campaigns
Focus Minerals Ltd. (ASX: FML) is pleased to announce results from recent exploration drilling campaigns conducted on priority targets at Coolgardie and Laverton.

| Craiggiemore | 4.7m @ 9.28g/tfrom 212m in CMDD348 |
During its recent exploration campaigns the Company drilled 43 holes at Laverton for 6,440m of RC and 2,376m of diamond core. At Coolgardie, 31 holes were drilled for 6,698m of RC and 1,215m of diamond core.
Drilling commenced in late March and finished in June, with three projects drilled in Coolgardie and six in Laverton. The programs varied from tenement maintenance work to deep diamond drilling. A full table of significant intersections is attached.
“We are pleased to see such exciting results from our first major exploration drilling campaign for the year” commented Focus Minerals Interim CEO, Wanghong Yang, “These results bolster Focus’ commitment to a thorough exploration program and we will follow them up with additional drilling on our advanced targets.”
Focus has planned additional RC and diamond core drilling for the coming quarter. It is also in the final stages of developing plans for copper exploration in the Admiral Hill trend (Laverton) and a geophysical investigation of the Company’s Nepean Nickel project. Both of these programs are expected to commence in the coming quarter.

Coolgardie Gold Project*

Bonnie Vale
13 holes were drilled at Bonnie Vale for 2,874m (Figure 3 presents one of the holes). The program was designed to test extensions to high-grade mineralised reefs historically mined underground, including the Westralia, Bonnie Vale and Vale of Coolgardie mines. Bonnie Vale is one of the largest and highest grade historic mines in the Coolgardie field, however it has received little effective exploration in the modern era due to holes being too shallow, or not effectively targeted. The majority of previous drilling in the area was carried out using shallow RAB, which is ineffective in testing reef structures dipping at between 45 and 60 degrees.
Following up on work commenced by Coolgardie Gold in the early 1990’s, the Company digitised the main workings, which proved to be vital when planning and orienting drill holes.
The initial holes targeting the upper portions of the Westralia and Callisto reefs did not intersect significant mineralisation, however two significant intersections were drilled on the Bonnie Vale and Vale of Coolgardie structures, namely 6.0m @ 9.45g/t from 158m BONC035 and 6.0m @ 7.12g/t from 95m in BONC033 (see Table A below).
A second round of RC drilling at Bonnie Vale will commence in the coming quarter, following up on these early results.
Brilliant
At Brilliant 14 holes were drilled for 4,264.5m. This program was designed to provide additional structural and assay data on deep targets building on the success of the Brilliant Deeps program completed in H2 2013, with all holes drilled beneath the current Brilliant pit (Figure 2). One hole at the northern end of the program could not be completed due to a lost rod string; this is expected to be recovered in the next round of drilling.
Results from the Brilliant program were sufficient to justify further drilling at depth. The highergrade zones are particularly significant as FML’s intention is to define sufficient tonnage at a robust grade to justify future underground mining (see Table A below).
During the second half of 2014 the Company intends to concentrate on exploring to the north of Brilliant, with an RC program currently awaiting DMP approval. This work is part of the longer-term view to thoroughly define mineralisation along the 2.5km-long Brilliant trend. Moving into 2015 the Company will continue infill drilling on the Brilliant Deeps area, which is now an advanced brownfields project.
Boundary
At the Boundary pit three RC holes were drilled for 774m, bracketing the known mineralisation at depth to test whether the deposit had sufficient strike and dip extent to justify further work. This drilling was unsuccessful in defining significant gold values, and no further work is planned.
*Collar locations for Coolgardie targets are presented in Figures 7 to 9.

Fish
11 holes were drilled at Fish, including 1,942m of RC drilling and 1,435.1m of diamond tails. Fish was originally drilled by WMC and mined as an open pit operation by Crescent Gold, with gold mineralisation hosted within a steeply-dipping BIF unit. The geological interpretation had shallowdipping granitic intrusions cutting off the orebody at depth, which resulted in a common view that the prospect had little depth potential despite the relatively high grades mined in the pit.
A reinterpretation of Fish conducted by FML geologists in late 2013, in conjunction with re-logging of old drill core, led to a complete re-appraisal of its prospectivity. The Company now believes the BIF unit to be relatively continuous, although folded, at depth rather than being faulted off and displaced by the granites. The recent drilling program was intended to test this hypothesis.
Results appear to support the new interpretation, although there is more complexity to the BIF units than expected. The new data will be added to a revised mineralisation interpretation before any further drilling is proposed (see Table A below).
Lord Byron
Two RC holes were drilled at Lord Byron, principally to keep the tenement in good standing but also testing mineralisation on flat structures adjacent to the existing open pit. The holes intersected a number of mineralised zones, and the new data will now be modelled in Leapfrog to assess its significance in relation to the rest of the data set (see Table A below).
Lancefield
Twelve RC holes were drilled for 1,338m testing a number of shallow positions along the strike of the West Lode. All holes intersected the lode position, with mixed results in terms of gold values. The best result was 2m @ 59.76g/t from 50m in LFRC002 (see Table A below).
West Lode was targeted because it remains relatively under-explored, and anecdotal evidence from previous explorers indicates the West Lode contains non-refractory mineralisation whereas the Main Lode contains a significant refractory component.
Craiggiemore
13 holes were drilled at Craiggiemore, including 1,926m of RC drilling and 940.4m of diamond core. This program was designed to test extensions to BIF-hosted mineralisation beneath the West Lode, which was successfully mined in the Craiggiemore pit (see Table A below).
The drilling indicates an unknown structural feature terminates mineralisation on the West Lode, however there is currently insufficient data to interpret or model this structure accurately. The drilling returned a best result of 4.7m @ 9.28g/t Au from 212m in hole CMDD348, however this mineralisation represents the Craiggiemore East Lode.
Prendergast Well
Drilling at Prendergast Well was designed to test mineralisation previously identified in shallow RAB holes. Four RC holes were drilled for 640m. The best result was 2m @ 4.68g/t from 46m in hole PWRC004, and no further work is planned at this stage.
Gladiator
Two RC holes were drilled for 300m. No significant intersections were received. No further work is planned at this stage.

This report relates to results for Reverse Circulation (RC) and diamond core drilling of Focus Minerals Coolgardie and Laverton Project areas. The summary table below lists metres drilled by drill type. The diamond tails are a sub-set of the RC holes. RC percussion drill chips were collected through a cyclone and cone splitter. Samples were collected on a 1m basis. 4m composite samples were collected manually using spear sampling of green bags. Core was sampled across identified zones of mineralisation by site geologists. Diamond core sample widths varied between a minimum of 0.2m and a maximum of 1m. |

| Total | 43 | 8,815.5 | Total | 30 | 7,912.5 | |
| RC chips were passed through a cone splitter to achieve a sample weight of approximately 3kg. The splitter was levelled at the beginning of each hole using a bullseye level. Any RC composite samples returning an assay value of 0.2g/t Au or greater were then re-assayed in 1m intervals by submitting the 1m cone-split samples for fire assay by 40g charge. At the assay laboratory all samples were oven dried, crushed to a nominal 10mm using a jaw crusher (core samples only) and weighed. Samples in excess of 3kg in weight were riffle split to achieve a maximum 3kg sample weight before being pulverized to 90% passing 75µm. The samples were then prepared for fire assay. |

| When visible gold was observed in RC chips, this sample was then flagged by the supervising geologist for the benefit of the laboratory. The diamond core was marked up for sampling by the supervising geologist during the core logging process, with sample intervals determined by the presence of mineralisation and/or alteration. The core was cut in half using an Almonte automatic core saw, with half-core samples submitted to Kalgoorlie assay laboratories for fire assay analysis by a 40g or a 50g (Diamond half core only) charge AAS finish. |
||||||
| Drilling techniques |
All drilling was completed using either an RC face sampling hammer or NQ2- size diamond core. All drill core was oriented by the drilling contractor using an Ezy-mark system. All holes were surveyed upon completion of drilling using a north-seeking gyroscope. Deeper diamond holes at Brilliant were surveyed inside the drill rods; all other holes were surveyed open-hole. |

| RC sample recovery was recorded by a visual estimate during the logging process. |

|---|---|---|
| Drill sample recovery |
The core samples were oriented, marked into metre intervals and compared to the depth measurements on the core blocks. Any loss of core was noted and recorded in the drilling database. |
|
| All RC samples were drilled dry whenever possible to maximize recovery, with water injection on the outside return to minimise dust. |
||
| Study of sample recovery versus gold grade does not indicate a bias in the gold grade caused by any drop in sample recovery. |
||
| Logging | All RC samples were geologically logged to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present. All diamond core was logged for structure, and geologically logged using the same system as that for RC. The logging information was recorded into acQuire format using a Toughbook notepad and then transferred into the company’s drilling database once the log was complete. |
|
| Logging was qualitative, however the geologists often recorded quantitative mineral percentage ranges for the sulphide minerals present. Diamond core was photographed wet and dry one core tray at a time using a standardised photography jig. Samples from RC holes were archived in standard 20m plastic chip trays. |
||
| The entire length of all holes (RC or diamond) are logged. | ||
| Sub-sampling techniques and sample preparation |
Core samples were taken from half core, cut using an Almonte automatic core saw. The remainder of the core was retained in core trays tagged with a hole number and metre mark. |
|
| RC samples were cone split to a nominal 2.5kg to 3kg sample weight. The drilling method was designed to maximise sample recovery and delivery of a clean, representative sample into the calico bag. Where possible all RC samples were drilled dry to maximise recovery. The use of a booster and auxiliary compressor provide dry sample for depths below the water table. Sample condition was recorded (wet, dry or damp) at the time of sampling and recorded in the database. |
||
| The samples were collected in a pre-numbered calico bag bearing a unique sample ID. Samples were crushed to 75µm at the laboratory and riffle split (if required) to a maximum 3kg sample weight. Gold analysis was determined by a 40g charge fire assay with an AAS Finish or a 50g charge AAS Finish (diamond core only). The difference in fire assay charge size was simply due to the use of two different commercial laboratories during the drilling campaign. |
||
| The assay laboratories’ sample preparation procedures follow industry best practice, with techniques and practices that are appropriate for this style of mineralisation. Pulp duplicates were taken at the pulverising stage and selective repeats conducted at the laboratories’ discretion. |
||
| FML inserts 2 standards and takes 4 duplicates for every 100 samples. |

|---|---|---|
| Field duplicates were collected from the cone splitter on the rig for RC samples at a frequency of one duplicate every 20 samples, excluding the 100th sample as this was a standard. Diamond core duplicates were not taken during this drilling program. Regular reviews of the sampling were carried out by the supervising geologist and senior field staff, to ensure all procedures were followed and best industry practice carried out. |
||
| The sample sizes were considered to be appropriate for the type, style and consistency of mineralisation encountered during this phase of exploration. |
||
| Quality of assay data and laboratory tests |
The assay method and laboratory procedures were appropriate for this style of mineralisation. The fire assay technique was designed to measure total gold in the sample. |
|
| No geophysical tools, spectrometers or handheld XRF instruments were used. | ||
| The QA/QC process described above was sufficient to establish acceptable levels of accuracy and precision. All results from assay standards and duplicates were scrutinised to ensure they fell within acceptable tolerances. |
||
| Verification of sampling and assaying |
Significant intervals were visually inspected by company geologists to correlate assay results to logged mineralisation. Consultants were not used for this process. |
|
| Normally if old historic drilling was present, twinned holes are occasionally drilled to test the veracity of historic assay data; however no twinned holes were drilled during this program. |
||
| Primary data is sent in digital format to the company’s Database Administrator (DBA) as often as was practicable. The DBA imports the data into an acQuire database, with assay results merged into the database upon receipt from the laboratory. Once loaded, data was extracted for verification by the geologist in charge of the project. |
||
| No adjustments were made to any current or historic data. If data could not be validated to a reasonable level of certainty it was not used in any resource estimations. |
||
| Location of data points |
Drill collars were surveyed after completion, using a DGPS instrument. Down-hole surveys were completed using a north-seeking gyroscope operated by a qualified contractor. |
|
| All coordinates and bearings use the MGA94 Zone 51 grid system. | ||
| Focus utilises Landgate sourced regional topographic maps and contours as well as internally produced survey pick-ups produced by the mining survey teams utilising DGPS base station instruments. |
||
| Data spacing and distribution |
Drill spacing across the Laverton and Coolgardie prospects varied depending on the exploration stage that the drill target currently existed. Drilling varied from wide spaced exploration RC drilling to precisely placed diamond tails designed to test mineralisation at depth and along strike. |
|
| The data spacing of the drilling across Focus’s prospects during this campaign was not considered sufficient to be used in a Mineral Resource; the majority of drilling was completed to establish continuity of mineralisation and alteration at depth. |

| Intercepted mineralisation will be digitized and incorporated into existing models or to create new models as required. Additional infill drilling would be required before this mineralisation can be used in the estimation of a Mineral Resource or Ore Reserve. |
||
| Sample compositing has not been applied to the reporting of exploration results. | ||
| Orientation of data in relation to geological structure |
Drilling was designed based on known geological models, field mapping, verified historical data and cross-sectional interpretation. Drill holes oriented at right angles to strike of deposit, with dip optimised for drill capabilities and the dip ofthe orebody. |
|
| No orientation and sampling bias has been recognised in the drilling data to date. | ||
| Sample security |
Laverton Gold Project | Coolgardie Gold Project |
| All samples are bagged in a tied numbered calico bag, grouped into larger polyweave bags and cable tied. Polyweave bags are placed into larger Bulka Bags with a sample submission sheet and tied shut. Consignment note and delivery address details are written on the side of the bag and picked up by Coastal Midwest and delivered directly to the Kalgoorlie laboratory. |
All samples were reconciled against the sample submission with any omissions or variations reported to FML. All samples were bagged in a tied numbered calico bag, grouped into green plastic bags. The bags were placed into cages with a sample submission sheet and delivered directly from site to the Kalgoorlie laboratories by FML personnel on a daily basis. |
|
| Audits or reviews |
A review of sampling techniques was carried out by Roredata Pty Ltd in late 2013 as part of a database amalgamation project. Their only recommendation was to change the QA/QC intervals to bring them into line with the FML Laverton system, which uses the same frequency of standards and duplicates but has them inserted at different points within the numbering sequence. |

Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | Laverton Gold Project | Coolgardie Gold Project |
|---|---|---|
| Mineral tenement and land tenure status |
All drilling was conducted on tenements 100% owned by Focus Minerals Limited or its subsidiary companies Focus Operations Pty Ltd and Focus Minerals Laverton Ltd. All tenements are in good standing. There are currently (July 2014) no registered Native Title claims over the Laverton or Coolgardie project areas. The only material royalty is that which includes the Lancefield tenement M38/37. Details of this royalty are included in the Company’s annual report published on the ASX website on 24/4/2014, listed on p84 of that report. |
|
| Exploration done by other parties |
As both Coolgardie and Laverton are historic mining areas, the projects have been explored by a number of companies in the past, in particular: The Fish and Lancefield projects were drilled (and mined, in the case of Lancefield) by Western Mining Corporation; Additional drilling was completed at Lancefield by Metex Ltd prior to the project being acquired by Crescent Gold; Fish open pit was mined by Crescent Gold and Focus Minerals; Craiggiemore was an historic underground mine, with an open pit mined by Ashton Gold and subsequently Crescent Gold; The Brilliant pit was initially mined by the Brilliant-Tindals Joint Venture. It was subsequently expanded after further drilling by Herald Resources’ subsidiary Goldfan. More recent drilling was completed by Focus Minerals; Bonnie Vale is the site of a number of historic workings including the “Varischetti Mine” (Westralia). Modern exploration has been conducted by Coolgardie Gold NL, Gold Mines of Coolgardie and Focus Minerals. |
|
| Geology | The company is exploring for Archaean lode-style gold deposit at both projects. | |
| Laverton Gold Project | Coolgardie Gold Project | |
| Lancefield mineralisation occurs on thrust planes dipping at approximately 45 degrees to the east. Mineralisation tends to be sulphide-rich, with most mining development occurring on the Main Lode which is typically a refractory mineralisation style. There has been less development and less drilling within the West Lode. Anecdotal evidence suggests the West Lode contains zones of free-milling mineralisation. Fish and Craiggiemore are both BIF- hosted orebodies, with gold mineralisation occurring within steep- dipping BIF units. At both areas there is some structural complexity due to late-stage faulting and/or shear-related folding which is currently the subject of investigation by FML geologists. |
Bonnie Vale mineralisation is historically contained within large (300m strike length) planar reef structures on or near the contact of the Bonnie Vale tonalite and an overlying ultramafic unit. FML drilling is investigating potential extensions to these structures at depth and along strike. Brilliant contains gold mineralisation on sheared basalt-ultramafic contacts and also within silicified intrusive diorite bodies conformable to the stratigraphy, dipping steeply to the WSW. Brilliant is an advanced brown-fields project. |
