ASX ANNOUNCEMENT
24 May 2017
Focus Minerals Ltd Coolgardie Operational Update
Overview of Recent Coolgardie Activities
Since the previous Coolgardie Exploration Update (ASX 25 January 2017), Focus Minerals Ltd (“Focus” or the “Company”) has continued infill drilling at Brilliant, as well as exploration drilling at Bonnie Vale and Lindsays North. Infill drilling at Brilliant continues to increase the mineralised footprint of the system and a resource update is expected once the current program is completed early next month and all assay data is received. Exploration drilling at Bonnie Vale and Lindsays North has also returned encouraging results and follow-up work is currently being planned. The location of each of these programs are presented in Figure 1.
In addition to drilling at Coolgardie, Focus has been continuing work on the Preliminary Feasibility Study for re-starting operations; it is due for completion in June 2017. As part of that study, Focus has been updating select Mineral Resource estimates from JORC 2004 to JORC 2012 standards. This release includes an updated Mineral JORC 2012 compliance Mineral Resource estimate for the Greenfields deposit based on historic drill data.

Brilliant Exploration Update
Since the previous ASX release on 7 April 2017, Focus has continued drilling at Brilliant with an additional 34 drill holes completed to date (26 RC holes for 5,252m and 8 RC/diamond holes for 3,629.0m) aimed at further increasing the Mineral Resource estimate. The current round of drilling has extended the mineralised footprint at Brilliant as well as increased the confidence of mineralisation continuity within both the underground and open pit resource areas (See Figure 2) . The recent drilling brings the total year to date drilling at Brilliant to 52 RC holes (for 11,202m) and 12 RC/DD holes (for 5,306.2m).
At the time of reporting, drilling at Brilliant is ongoing. The current campaign is due for completion in early June 2017 and a Mineral Resource update is expected to follow shortly thereafter. Full significant results from this drilling are listed in Table A, however highlights include:
-
TND17030 3.3m @ 5.04g/t Au from 487.2m

Bonnie Vale Exploration Update
Exploration drilling at Bonnie Vale to date in 2017 has consisted of three RC holes for 813m and three RC/DD holes for 1,075.6m (Figure 3). The three RC holes and one of the RC/DD holes were designed to test for the southward and down-dip continuation of the Quarry Reef Lode approximately 90m to the southeast of the 2016 resource boundary. The remaining two diamond holes were designed to target the Westralia Reef to assess the potential for lode extensions. Drilling was generally encouraging and follow-up work is being planned. Full significant results are included in Table A, but highlights include:
-

Greenfields Deposit Mineral Resource Update
Focus has upgraded the compliance of its Greenfields deposit to JORC 2012 standards following a review and completion of the Table 1 reporting requirements for the currently reported (2004 compliant) block model.
The JORC 2012 Greenfields Mineral Resource is reported above a 1g/t cut-off for open pit resources above 265mRL and comprises:
-
Indicated Resource 1.328Mt at 1.7g/t gold for 72,500 contained ounces
-
Inferred Resource 0.066Mt at 2.0g/t gold for 4,500 contained ounces
-
Total Mineral Resource 1.394Mt at 1.7g/t gold for 77,000 contained ounces
The Mineral Resource is reported on a dry tonnage basis. See the attached JORC Table 1 for additional details. Discrepancies may occur due to rounding. Historic mining depletion has been taken into account.

The Greenfields Project forms part of Focus Minerals’ tenement portfolio in the highly prospective Coolgardie region of Western Australia. The deposit has previously been an open pit gold producer, mined in stages from 1986 to mid-2013 with production figures of approx. 51,000oz at an average grade of 1.8g/t. Figure 5 presents a plan view of the Greenfields deposit and Figure 6 presents a representative cross section.

Previously, the JORC 2004 Greenfields resource has been reported as a total resource above a 1g/t grade cut-off with no RL cut-offs used. Following preliminary feasibility work, it has been determined the 265mRL is an appropriate RL, for open pit mining considerations, to be reported above. The previously reported JORC 2004 Greenfields resource is tabulated below:
-
Indicated Resource
-
Inferred Resource
-
Total (previous) Mineral Resource
-
1.898Mt at 1.6g/t gold for 96,000 contained ounces
-
0.705Mt at 1.4g/t gold for 32,000 contained ounces
-
2.603Mt at 1.5g/t gold for 128,000 contained ounces
Coolgardie Forward Program
As stated, drilling is ongoing at Coolgardie. Additional RC and diamond drilling is currently in progress at Brilliant and the current programme is expected to be completed early June. A Mineral Resource Estimate update will be completed once all assay data for this program have been received. Further RC drilling at Bonnie Vale and Possum is planned as the next phase of drilling and other drill targets are currently being ranked for exploration during the second half of 2017. The preliminary feasibility study is in progress and is anticipated to be completed by the end of June 2017. Ongoing weather delays have hampered the planned Lake Cowan gravity survey, although this survey is still anticipated to be completed this year.

Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Commentary |
|---|---|
| Sampling techniques |
This report relates to results from Reverse Circulation (RC) drilling and diamond core drilling. The information of sampling techniques below applies to the drill holes drilled by Focus Minerals (FML) only. RC percussion drill chips were collected through a cyclone and cone splitter. Samples were collected on a 1m basis. Diamond core was sampled across identified zones of mineralisation by site geologists, the sample widths varied between a minimum of 0.2m and a maximum of 1m. 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. The spoils were collected in green bags at 1m intervals. 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 pulverised to 90% passing 75μm. 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 and the same half of the core was routinely sent to the laboratory for analysis. Some of the diamond core has been ¼ core sampled, although this is only in a minority of cases. Historic RC holes have been sampled on 1m or as 2m composite. It is unsure how the composite sampling for pre-Focus drilling would have been undertaken. |

-
Drilling All FML drilling was completed using an RC face sampling hammer or NQ2/HQ3 size diamond core. Where achievable, all drill core was oriented by the drilling contractor
-
techniques using an Ezy-mark system. Most holes were surveyed upon completion of drilling initially using an electronic multi-shot (EMS) camera and since Sept 2013 a northseeking gyroscope; holes were surveyed open-hole prior to 2017. Since late 2016, all holes were surveyed using various gyroscopes (non-north-seeking paired with an azimuth aligner and north-seeking) by the drill contractors whilst drilling.
Drill sample
-
FML sample recovery was recorded by a visual estimate during the logging process.
-
All FML RC samples were drilled dry whenever possible to maximise recovery, with
-
recovery water injection on the outside return to minimise dust.
-
Historic drill recovery has been sporadically recorded.
-
Logging The information of logging techniques below applies to the drill holes drilled by FML only.
-
All core samples were oriented where possible, 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 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 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 one core tray at a time using a standardised photography jig.
-
More recently, samples from RC holes were archived in standard 20m plastic chip trays.
-
The entire length of all holes are logged.
-
Historic RC holes have been logged at 1m intervals to record weathering, regolith, rock type, colour, alteration, mineralisation, structure and texture and any other notable features that are present.
-
Original drill logs have been viewed and used to validate data stored in acQuire for a majority of the pre-FML drilling.
-
Sub-sampling The information of sub-sampling and sample preparation below applies to the drill holes drilled by FML only.
-
techniques and 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
-
sample metre mark. RC samples were cone split to a nominal 2.5kg to 3kg sample weight. The drilling
-
preparation 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 initially by 40g aqua regia for the composite samples then 40g Fire Assay for individual samples with an ICP-OES or AAS Finish.
-
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.
-
Earlier FML QAQC checks involved inserting a standard or blank every 10 samples in RC and taking a field duplicate every 20 samples in RC. Field duplicates were collected from the cone splitter on the rig. Diamond core field duplicates were not taken, a minimum of one standard was inserted for every sample batch submitted. In

| more recent drilling no blanks were submitted, only standards every 25 samples with a duplicate taken off the rig every 20thsample. 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. Very little in the way of quality control data is available from sampling of the historic drilling that currently defines the Greenfields Resource. Drilling by FML aimed to confirm the geometry of the ore envelope and grade tenor encountered in historic drilling at Greenfields. |
| 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. Historic holes were validated against paper copies and WAMEX reports where possible. 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 |
FML drill collars were surveyed after completion, using a DGPS instrument. All drill core was oriented by the drilling contractor using an Ezy-mark system. Most holes were surveyed upon completion of drilling. Initially an electronic multi-shot camera was used until Sept 2013 when a north-seeking gyroscope tool was used. Holes were surveyed open-hole prior to 2016. Since late 2016, most drillholes were surveyed using various gyroscope systems (non-north-seeking gyroscopes paired with azimuth aligners and north-seeking gyroscopes) by the drillers whilst drilling, otherwise surveyed open hole using a north-seeking gyroscope. Since the start of 2017, gyroscopes were used for “single shot” surveys whilst drilling, otherwise a single shot Eastman camera downhole survey was used. All coordinates and bearings use the MGA94 Zone 51 grid system. FML 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. Historic hole collar survey methods are unknown although Gold Mines Coolgardie JV indicates collars were surveyed by company survey. |
| Data spacing and distribution |
At Brilliant, drill spacing within the resource area is a combination of 20mx20m, 20mx40m and 40mx40m. Outside of the resource area, exploration holes are more irregularly spaced. At Bonnie Vale, drill spacing within the resource area is generally 40mx40m although some exploration step-out holes are more irregularly distributed. At Lindsays North, drill spacing is irregular. At Greenfields, drilling has been conducted on 20m spaced grid lines on sections oriented across strike of the ore zone at an azimuth of either 20oor 200oand at various dips, with 10-20m collar intervals on section. Wider-spaced drilling exists at depth up to as wide as 40x80m. |

Orientation of Drilling was designed based on known geological models, field mapping, verified historical data and cross-sectional interpretation.
-
data in relation Where achievable, drill holes were oriented at right angles to strike of deposit, with dip optimised for drill capabilities and the dip of the ore body. Where drill holes are
-
to geological at a low angle to the known mineralisation trend, true widths are re-calculated based on the geology interpretation.
-
structure Sample All samples were reconciled against the sample submission with any omissions or variations reported to FML.
-
security 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.
-
Historic sample security is not recorded.
-
Audits or 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
-
reviews 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.
-
At Greenfields, significant data validation was completed by consultants Hellmann and Schofield in 2005 as part of a resource estimate.
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section)
| Criteria | Commentary |
|---|---|
| Mineral tenement and land tenure status |
All exploration was conducted on tenements 100% owned by Focus Minerals Limited or its subsidiary companies Focus Operations Pty Ltd. All tenements are in good standing. There are currently no registered Native Title claims over the Coolgardie project areas. |
| Exploration done by other parties |
Brilliant Project Brilliant has been explored and mined by various parties over time. The first phase of mining is believed to have taken place in the early twentieth century and would have consisted of prospecting shafts and limited underground mining. Mines Department records document treatment of 60 tonnes of ore producing 6.97oz of gold up to 1935. No other production is recorded. Open pit mining of the prospect commenced in the 1970’s with a number of parties processing ore through the Coolgardie State Battery. In 1980 a treatment plant was constructed at Brilliant by Tryaction Pty Ltd, who produced from an open pit. In the mid 1980’s Electrum NL bought into the project, forming a joint venture with MC Mining. They expanded the treatment plant and continued open pit mining in the Brilliant area. Recorded production by Electrum/MC Mining is 87,986 tonnes at 3.2 g/t Au for 9,000 ounces with a stripping ratio of 12.7:1 (Kirkpatrick, 1995). The project was subsequently purchased by Goldfan Limited (a wholly owned subsidiary of Herald Resources Ltd) in 1991 and incorporated into the Tindals Project. They initiated drilling programs which increased the known extent of mineralisation and completed further open cut mining to its present limits in the early 2000’s. Table 2 in the FML Combined Annual Report of 2008 states an estimated total production from Brilliant Pit of in excess of 1.1Mt @ 2.45g/t for 88,000 ounces. Bonnie Vale Project |

Gold Mines of Coolgardie Pty Ltd (GMC), MPI Gold Pty Ltd and FML have also run drilling campaigns of RC and Diamond at Greenfields
Geology
Brilliant Project
- The deposit lies on the western margin of the Archaean Norseman – Menzies Greenstone Belt. Host rocks at Brilliant are a sequence of Archaean Basalts and Ultramafics, which have been intruded by a suite of porphyry dykes (also described as granodiorites). The porphyries host the bulk of the mineralisation, occurring in two orientations, steeply dipping (70 - 80°) with an average width of 3 to 5m, or flatter dipping (20 - 40°) with widths of up to 2m. Mineralisation consists of a stock work of quartz / sulphide micro-veining and albitic alteration of the porphyry.
Bonnie Vale Project
- Locally, the geology is dominated by the Bonnie Vale tonalite, with an ultramafic to the east and west of the tonalite in structural contact. This ultramafic has been logged as a cargonate-altered ultramafic and described as a komatiite in Halberg’s regional mapping. Mineralisation is hosted within large (strike length > 300m) quartz reefs which range in thickness from centimetre scale to several metres. The known reefs strike sub-parallel to the edge of the tonalite, with the main orientations being an easterly dip (e.g. Westralia) or northeast (Bonnie Vale, Quarry Reef) of 40 to 60 degrees.
Lindsays North Project
- Lindsays North is located along the contact between a hangingwall ultramafic unit and a footwall basalt unit, which has been intruded by a suite of late felsic porphyry dykes. Mineralisation is hosted within or adjacent to the felsic porphyries. These felsic porphyries are persistent along strike within the contact zone for several kilometres to the east and south and host significant mineralisation at Bayleys approximately 1.5km along strike to the southeast.
Greenfields Project
- The Greenfields deposit is located within the Greenfield Dolerite Sill within the Coolgardie Greenstone Belt. There are three rock types present in the pit: dolerite, felsic volcaniclastics (sediments) and ultramafics. The dolerite is sub-divided into four separate units known as the unit 3, 4, 5 and 6 in the pit area. These are separated on mineralisation, alteration, veining and grain size variations. These units all have a WNW strike and steep dip with the gold mineralisation best developed within the unit 4 dolerite, with minor occurrences located in units 3 and 5. Within the dolerite sill are shallow to moderately, NE-NW dipping quartz veins which often display higher grade gold mineralisation with visible gold identified in some drill core samples. Sulphides evident in logging include arsenopyrite and pyrrhotite. The dolerite sill and felsic volcaniclastics of the Kurrawang Formation are separated by the Greenfields Fault which runs through the pit at 280-290[o] azimuth.

Section 3 Estimation and Reporting of Mineral Resources - Greenfields
(Criteria listed in section 1, and where relevant in section 2, also apply to this section. This section refers exclusively to the Greenfields Resource Update)
| Criteria | Commentary |
|---|---|
| Database integrity |
Data was geologically logged electronically, collar and downhole surveys were also received electronically as was the laboratory analysis results. These electronic files were loaded into an acQuire database by either consultants rOREdata or the company in-house Database Administrator. Data was routinely extracted to Microsoft Access during the drilling program for validation by the geologist in charge of the project. FML’s database is a Microsoft SQL Server database (acQuire), which is case sensitive, relational and normalised to the Third Normal Form. As a result of normalisation, the following data integrity categories exist: Entity Integrity: No duplicate rows in a table, eliminated redundancy and chance of error. Domain Integrity: Enforces valid entries for a given column by restricting the type, the format or a range of values. Referential Integrity: Rows cannot be deleted which are used by other records. User-Defined Integrity: Business rules enforced by acQuire and validation codes set up by FML. Additionally, in-house validation scripts are routinely run in acQuire on FML’s database and they include the following checks: Missing collar information Missing logging, sampling, downhole survey data and hole diameter Overlapping intervals in geological logging, sampling, down hole surveys Checks for character data in numeric fields The historical Greenfields drill data was validated by the Focus data management team and the Project Geologist. This involved collaborating all collar, downhole survey, geology and assay data with existing hardcopy material as well as displaying the holes in three dimensions in Surpac to determine any unusual or unlikely trends in the data so that it could be rectified before loading into the Focus site database. This process was thorough and took a couple of months for the team to complete. |
| Site visits | Hannah Kosovich, the Competent Person for the Greenfields Resource Estimate is FML’s Resource Geologist, and conducts periodic site visits. Wesley Groome, the Competent Person for the exploration results, is Senior Geologist at FML and conducts regular site visits |
| Geological interpretation |
All available drill hole and historic mining data was used to guide the geological interpretation of the mineralisation. The majority of the resource occurs in what has been labelled the Unit 4 Dolerite. The remaining minor lodes occur within the less well mineralised (and altered) Unit 3 and Unit 5 Dolerites. The mineralised geological interpretation was digitised in GEOVIA Surpac software on a section by section basis. The contact of the Dolerite 4 was used to guide the interpretation or an approximate 0.5g/t cut-off was used where the contact was obscure. Significant internal dilution included for continuity of modelling the Dolerite contact. Minor deviation only of the lode geometry was noticed between drill holes along |

| strike and down-dip. Minor lodes with less continuity and sample numbers were also interpreted. |
|
|---|---|
| Dimensions | The resource extends over a strike length of over 300m (from 30030mE to 30350mE) and includes the ~200m interval from the mined surface down to the 120mRL. The thickness of the main lode varies from average thickness of 20m near surface pinching to an average thickness of 10m at depth. |
| Estimation and modelling techniques |
158 holes were used in the estimate including 96 RC, 8 diamond core holes and 54 RC pre-collared diamond core holes for a total of 16,908.82. Samples within the wireframes were composited to even 2m intervals, the dominant sample interval from historic drilling. Residual samples that did not meet the minimum length criteria of the compositing process were appended to the adjacent sample so that all material within the wireframe was included The statistics of the 2m composites were analysed to determine if any top cutting was required. Top-capping of higher Au values within each domain was carried out with Au values above the cut-off grade reset to the cut-off grade. Skree plots and Cumulative Frequency plots were used to determine top cut grade which was 25 g/t Au and affected five samples. Variography was modelled for the Major, Semi Major and Minor axes on the main Unit 3 Dolerite. GEOVIA Surpac Software was used for the estimation. An Ordinary Kriging (OK) technique was selected using the variograms modelled in Surpac. Each domain was estimated separately using only its own sample values. No samples were shared between domains (hard boundaries). Minimum (8) and maximum (32) sample numbers were selected based on a Quantitative Kriging Neighbourhood analysis. An elliptical search was used orientated on the lode geometry and based on range of the Variograms. Three search passes were run in order to fill the block model with estimated Au values, with reduced minimum sample numbers and increased search distances. Block sizes for the model were 5m in Y, 20m in X and 5m in Z direction. Sub celling of the parent blocks was permitted to 1.25m in the Y direction, 5m in the X direction and 2.5m in the Z direction. Sub-blocking was used to best fill the wireframes and inherit the grade of the parent block. A 20° rotation in the Z axis (bearing rotation) was applied to the orientation of the blocks. This aligned the blocks with the WNW strike of the lodes. The estimate was validated by a number of methods. An initial visual review was done by comparing estimated blocks and raw drill holes. Tonnage weighted mean grades were compared for all lodes with the raw and top- capped drill hole values. There were no major differences. Swath plots of drill hole values and estimated Au grades by northing and RL were completed to review the trends of the raw data vs estimates and if too much smoothing of the grades had occurred. Comparisons between previous Greenfields block model estimates was also plotted as trend lines by elevation. |
| Moisture | Tonnages are estimated on a dry basis. |
| Cut-off parameters |
The Resources for Brilliant have been reported above a 1g/t cut-off for open pit above 265mRL, this is based on a preliminary whittle shell optimisation. |
| Mining factors or assumptions |
An existing open pit exists at Greenfields, mining would continue by cut-back and open cut extraction. |
| Metallurgical factors or assumptions |
In house metallurgical test work had been conducted on Greenfields samples and recoveries were in the plus 90% range. GMC who mined Greenfields from Dec 2003 to Jan 2005 had an overall reconciliation of ~96.9% of tonnes, 100.7% of grade and 101% of ounces milled compared to mined. |

| Environmental factors or assumptions |
Greenfields deposit occurs in an area of previous disturbance with an open cut pit and associated waste dump. The Three Mile Hill Processing Plant is currently on care and maintenance, but has all necessary tailing facilities etc. that would allow for a rapid restart of the plant. |
|---|---|
| Bulk density | Bulk densities of 1.8, 2.4 and 2.8 t/m³ were applied to Oxide, Transitional and Fresh resources respectively. The oxide and transitional values are based on values used in similar gold deposits. The fresh rock value is based on 32 measurements taken from recent Focus drill core using a water immersion method and is the average value of those samples. |
| Classification | Resources have been classified as either Indicated or Inferred based mainly on geological confidence in the geometry and continuity of the lodes. In addition, various estimation output parameters such as number of samples, search pass, kriging variance, and slope of regression have been used to assist in classification. Recent Focus drilling has confirmed the geological interpretation is sound and provided some quality assurance in the pre-Focus drilling. |
| Audits or reviews |
No external audits or reviews were formally carried out on the Greenfields deposit. |
| Discussion of relative accuracy/ confidence |
The mineral resource relates to global tonnage and grade estimates. The Greenfields pit has been mined in four campaigns in the modern era commencing in 1986 and finishing in 2005 producing some 0.98Mt @ 1.81g/t for 56,776 ounces (reconciled). The current model reports higher tonnages at a lower grade due to the internal dilution included in modelling the main dolerite unit, 1.38Mt @ 1.69g/t for 75,214 ounces. |
