– Operational Review Coolgardie Gold Project
Production during the December Quarter was 86,418 tonnes at 3.84 g/t . This predominately came from underground Perseverance production stoping and ore development at the Empress and Countess deposits, located within the Tindals Mining Centre. In addition, 2,340 tonnes at 8.96 g/t was produced at the Mount Project and trucked to Three Mile Hill.
Cash costs for the December Quarter were A$602 per ounce (including royalty costs). Production costs have increased slightly during the Quarter reflecting the increased mining activities and the early start-up costs of the Three Mile Hill Mill plant. These costs included staffing costs of mill shifts, early maintenance activities and increased training activities for new staff. Staff growth at Coolgardie has been from 38 employees in the September Quarter to 65 employees at the end of the December Quarter.
Total stockpiled ore at the end of the Quarter was 185,000 tonnes at 2.85 g/t containing approx 16,970ozs.
In October, Focus’ mining contractor, Barminco, mobilised a twin boom jumbo to site and commenced an aggressive development program in the Empress and Perseverance declines. The advance of the Countess decline allowed for simultaneous accessing of new production levels at Empress and Countess. During the Quarter, over 961 metres of decline and ore drives were completed at Tindals.
Simultaneously, the 140m exploration decline [3.5m x 3.5m] was completed at the Mount. Ore development of over 150m was also completed on the primary and secondary German lodes.

GOLD RESERVES AND STOCKS
Focus Minerals’ Reserve and Stocks position at end of December 2009 stood at 2 million tonnes @ 2.4 g/t for 157,000 contained ounces . This represents a 68% increase from last Quarter’s position of 767,000t @ 3.8g/t for 93,000 contained ounces and is due to this Quarters inclusion of the first open pit reserves. Work is ongoing to convert additional surface and underground resources to reserve in the coming Quarter.

Open Pit Reserves
Focus has begun the process of converting near-surface Resources to open pit Reserves. This will be an ongoing process supported by the Company’s extensive resource base and surface exploration. To date, Reserves have been completed for Greenfields, Big Blow and Dreadnought North.
Greenfields
A Maiden Reserve for has been generated for the Greenfields deposit. The Open Pit Probable Reserve is an estimated 1.1 million tonnes @ 1.7 g/t for 60,000 contained ounces at a strip ratio of 4.0.
Greenfields is an existing pit and the Reserve represents extensions to the existing pit along known mineralisation. The Greenfields pit is located adjacent to the Three Mile Hill processing facility. The conversion of the Greenfields Resource to Reserve highlights the potential in the Company’s resource base and represents a part of the ongoing technical work being conducted by Focus at Coolgardie.

Big Blow
A Maiden Reserve has been generated for the Big Blow deposit. The Probable Open Pit Reserve is an estimated 63,000 tonnes @ 2.2 g/t for 4,500 contained ounces at a strip ratio of 7.3. While relatively small, Big Blow is part of a package of probable smaller pits located around the current infrastructure at Tindals. Work is currently progressing on approvals to allow mining at Big Blow as part of a package of works. Recent drilling indicates that Big Blow has future underground potential and pit designs are taking this into account.
Dreadnought North
A Maiden Reserve for Focus Minerals has been generated for Dreadnought North. The Probable Open Pit Reserve is an estimated 54,000 tonnes @ 1.8 g/t for 3,100 contained ounces at a strip ratio of 4.2.
EXPLORATION
During the December Quarter, a total of four drilling rigs were operating on site as part of the Company’s aggressive resource definition, extensional and exploration programs.
Underground Exploration and Resources
Perseverance
Drilling during the Quarter focused on geophysical targets to the north and south of Perseverance - deep extensional drilling in the southern area and extensional drilling of the high-grade linking structure. Highlights from drilling during the Quarter include intercepts of:
-
0.95m @ 170.94g/t (visible gold) ;
-
3.14m @ 12.10g/t;
-
0.95m @ 21.33g/t;
-
5.76m @ 3.61g/t;
-
0.43m @ 49.0g/t; and
-
4.62m @ 10.32g/t.
The complete results from the drilling are provided in Table 4.
The drilling highlighted that potential continues to exist on the East Lode and high-grade linking structure in the southern area. The drilling closed off mineralisation immediately to the south above the 200mRL, but did reveal that potential still exists below this RL to the south, down dip and down plunge where the ore-body remains open.
These intersections (including a section of visible gold) are outside the current resource base and are over 100m below the current Perseverance workings (see Figure 1 below). This reinforces the Company’s belief that the areas surrounding the known deposits in the Tindals area have the potential to host additional high-grade mineralisation.
Down hole electromagnetic (DHEM) surveys were conducted on the drill holes targeting new geophysical targets. Analysis of the data produced some attractive anomalies in and around Perseverance (see Figure 1 below), where three priority targets were identified. Drill planning is currently underway on the first of these targets which sits at the 245mRL just to the north of the current Perseverance mine (see Figure 1 below).

Countess
A drill program at Countess focused on definition drilling of the Countess East Lode, with the holes extended to infill areas of the Tindals Lodes 40-80m below the last level historically mined at Tindals. Highlights from drilling during the Quarter include intercepts of:
-
5.72m @ 4.98g/t;
-
2.22m @ 4.85g/t;
-
2.48m @ 5.37g/t;
-
5.97m @ 4.48g/t; and
-
13.65m @ 2.54g/t.
The complete results from the drilling are provided in Table 5.
The drilling extended the mineralised zone in the East Lode which remains open to the north and at depth, while the Tindals intercepts verified the structure and grade below the existing workings.
Empress
Towards the end of the Quarter, drilling at Empress concentrated on definition drilling of the Empress Lodes which is +50m below the current development. Highlights from drilling during the Quarter include intercepts of:
-
3.32m @ 7.16g/t; and
-
1.16m @ 3.99g/t.

The complete results from the drilling to the end of the quarter are provided in Table 6.
The drilling verified the structure and grade below the current workings. Drilling continues at Empress, with step out exploration drilling to commence once the definition drilling has been completed.
Surface Exploration and Resources
Big Blow
An updated Resource model was completed during the Quarter on the Big Blow deposit. This was based on the recently completed drilling which verified the historical data and has lead to increased confidence in the interpretation. The updated resource at Big Blow is 373,000t @ 4.2g/t for approximately 50,400 contained ounces (Table 7).
This is comprised of:
-
An estimated Indicated Resource of 279,000t @ 3.7g/t for approximately 32,900 contained ounces ;
-
An approximate Inferred Resource of 94,000t @ 5.8g/t for approximately 17,500 contained ounces .
Exploration at Big Blow concentrated on drilling (including geotechnical drilling) to verify historical data, assist with pit designs and to provide material for metallurgical studies. Highlights from drilling during the Quarter included intercepts of:
-
3m @ 8.74g/t;
-
6m @ 4.23g/t;
-
10m @ 3.38g/t;
-
2m @ 6.49g/t; and
-
3.95m @ 4.55g/t.
The complete results from the drilling to the end of the quarter are provided in Table 8 .
The drilling verified the structure and grade of the Big Blow deposit, with the deposit remaining open at depth. The depth potential at Big Blow is the target of an exploration program to be drilled during the first Quarter of 2010.
Cookes
An updated Resource model was completed during the Quarter on the Cookes deposit, which was based on validation of historical data and a re-interpretation and review of the parameters used in the previous historic resource estimate. The updated resource at Cookes is an approximate Inferred Resource of 86,000t @ 2.6g/t for approximately 7,300 contained ounces . This represents a 30% increase on the historic Cookes resource of 5,600 ounces.
The updated resource was used to target drilling for a potential open pit. The drilling (including geotechnical drilling) was used to verify the historical data, target shallow extensions, assist with pit designs and to provide material for metallurgical studies. Highlights from drilling during the Quarter included intercepts of;
-
0.9m @ 11.15g/t;
-
4m @ 3.79g/t;
-
3m @ 4.18g/t; and
-
12m @ 3.70g/t.
The complete results from the drilling to the end of the quarter are provided in Table 9.
The drilling verified the structure and grade of the Cookes deposit, and also confirmed that the deposit remains open to the north and at depth. The drilling also intersected a few parallel structures to the west of the main Cookes ore body. Further results from the program are pending.

The Mount Project – Exploration Decline Confirms Grade and Structure
The Company’s strategy of developing an exploration decline into The Mount has proven successful this Quarter, − − with the 350,000 ounce Mount Project which lies 80km south of Focus’ Tindals Mining Centre at Coolgardie already starting to play a key role in lifting the Company’s production profile following Three Mile Hill coming into full operation.
After securing all necessary mining permits and environmental approvals in September 2009, Focus has made significant progress at the Mount. This has included the completion of a 140m exploration decline, which has accessed the three German Lodes and allowed confirmation of both the geological structure and grade (with face grades during the initial cross cut of 13.0 g/t). It also provides an access for further development activities.
Approximately 94m strike drive has been developed on the German Main Lode and 38m of strike has been developed on the German West Lode, approximately 50m below surface. Both lodes are still being driven north and south with faces to date averaging over 8.0 g/t with ore widths of approximately 2.0 metres. To date 2,300t @ 9g/t has been trucked to Three Mile Hill for processing.
Currently in progress and planned are the establishment of second means of egress, ventilation circuit and both an incline and a decline to continue exploration and to set up for initial stoping activities.
Three Mile Hill Refurbishment
On the 24[th] December, Three Mile Hill Mill was handed over to Focus Minerals. This was the culmination of a very intensive nine months for Focus Minerals employees and construction contractors, Como Engineers.
Como Engineers commenced work on the project on the 4[th] of April 2009 under a fixed price and scope contract of A$16.95 million. Outside of this, Focus undertook over A$2.9 million worth of other work in order to ensure that the plant complied with all current health and safety and material handling regulations. This additional spend also ensured that other plant infrastructure not included in the refurbishment project was up to a standard set internally by Focus for the commencement of milling operations in December (Fig 1, Fig 2).
The Three Mile Hill plant has an annual capacity of 1.2 million tonnes, enabling Focus to increase production to an expected 80,000oz this year and more than 100,000oz next year. Importantly, the Three Mile Hill plant will enable the Company to cut operating costs and benefit from a more consistent production profile.
In October 2009, approximately A$4m was allocated from an A$8m capital raising to purchase significant spares with long lead times for Three Mile Hill.
A large proportion of the long lead items and critical spares have been ordered, with some items already delivered to site or being held as consignment stock by local suppliers. The remainder of the outstanding spares and long lead items are expected to be delivered during the coming months.
The main work areas of the 2009 Refurbishment project were:
-
Purchase and installation of new primary, secondary and tertiary crushers (including the rebuilding of much of the crusher foundations); (Fig 3, Fig 4)
-
The complete rebuild and refurbishment of the fine ore bin and screen; (Fig 5, Fig 6)
-
The complete refurbishment of the mill and the complete rebuilding of the mill foundations; (Fig 7, Fig 8)
-
The complete physical refurbishment of all tanks and mechanical infrastructure associated with the tanks; (Fig 9, Fig 10)
-
A new gold gravity circuit; and
-
A new gold room facility including elution and stripping and carbon regeneration circuits (Fig 11, Fig 12, Fig 13).

To demonstrate the extensive level of work carried out a series of before and after photos on the different components of the plant is provided in Appendix B. The Mill ran successfully through the Christmas period and gold was first poured on Wednesday the 13[th] of January, 14 days after start-up.
To date, the refurbishment is 100% complete with expenditure totaling $16.95 million of the fixed value contract of $16.95 million. The project progress cost break down is provided below in Table 3 :

CORPORATE
Hedging and Debt
During early October 2009, Focus delivered the balance of 1,200 ozs under the gold hedging facility. The Company has cleared all hedge facility commitments and is now completely unhedged to the gold price.
In December, Focus made its final $3.75m payment to Investec Bank (Australia), clearing the A$17m loan facility established in 2008. It is important to note that A$13.4m of this facility was repaid during Calendar year 2009. Focus also completed repayment of the A$2m unsecured loan provided by CBR Group Inc during the Quarter.
Following these payments Focus enters 2010 100% debt-free.
Cash and Bullion
Revenue for the Quarter was A$14.95M million generated from the sale of 13,024 ounces of gold at an average price received of A$1,147.46/oz.
At 31 December, 2009, Focus had the following Australian dollar amounts available;
| Cash at Bank | $7.513 million | |
|---|---|---|
| Bullion on Hand | $1.336 million | |
| Total Cash and Equivalents | $8.849 million | |
Excludes $982,000 held in secured deposit accounts supporting bank guarantees and bonds required under mining tenement conditions.

Capital Raising
During October 2009 Focus completed an $A8m capital raising via a share placement to institutional investors. This raising was undertaken to expedite funding for big ticket spare parts for the Three Mile Hill mill and for increased exploration and Reserve definition drilling.
− Approximately half of the proceeds which were raised through the placement of 200 million shares at 4 cents each − to institutional clients of Petra Capital have or will be used to acquire crucial spare parts for Focus’ refurbished Three Mile Hill mill.
− During the Quarter, breakdowns at the Greenfields toll treatment facility while having no effect on Focus’ − production served as a timely reminder that from time to time process plants do breakdown and led Focus to rethink its strategy surrounding long-lead item spare parts.
This raising underpinned the Company’s strong financial position, but also recognised the critical nature of ensuring future milling operations could continue without major incident once the refurbished plant was commissioned. The purchase of spare parts significantly mitigates this risk.

BACKGROUND INFORMATION – FOCUS MINERALS LTD
Focus Minerals Ltd (ASX: FML ) is an Australian‐based exploration and development group whose focus is to become a significant gold and nickel producer in the Coolgardie‐Kalgoorlie‐Widgiemooltha region of Western Australia.
Focus Minerals is the largest landholder in the Coolgardie Gold Belt located in Western Australia, 560km east of Perth and 35km west of the ‘Super Pit’ in Kalgoorlie‐Boulder. More than 2.6 million ounces of gold has been produced from the Coolgardie gold belt alone since 1892. Focus holds the mineral rights to more than 210sq km of tenements including an extensive inventory of Measured, Indicated and Inferred gold resources as well as the 1.2mtpa Three Mile Hill processing plant.
Focus commenced maiden commercial gold production in April 2008 through ore sourced from the Company’s flagship Perseverance Deposit (Probable Reserve of 129,000oz). Earlier this year, the nearby Countess Deposit (Probable Reserve of 29,000oz) was also brought into production with ore from both deposits currently being milled at the nearby Greenfields treatment plant.
Notes to accompany the Mineralised Resource Statements
The notes below are for the Perseverance, Empress, Countess and Greenfields Resource updates which have not been previously released to the ASX.
Perseverance is a series of quartz‐sulphide veins with highly variable sulphide content of <1% to 100% hosted in basalt and garnetiferous diorite intrusions. Mineralisation occurs where a diorite unit is offset by the fault on which the deposit lies. The brecciated Main Lode East occurs along the fault zone within the basalt unit with a number of thinner Sulphide Lodes to the west. All of the lodes strike 030° and dip 80°W with the average thickness of Main Lode East being 3 to 5m and the Sulphide Lodes being less than 2m thick. The Sherlaw Lodes are a series of relatively close spaced narrow (<2m) lodes running sub‐parallel to the main lodes. Mineralisation in these lodes is patchy and higher grades may be related to linking structures between the various lodes. Dextral movement along the fault zone has resulted in a mineralised linking structure below the 250mRL. This mineralised structure has high sulphide content and extends from the Main Lode East striking 230° and dips 80°W with an average thickness of 2 to 6m. There are numerous sub‐parallel lodes within the fold nose of the diorite on the western side of the fault zone. The shape of the

mineralised lodes suggests that there is a structural control (the dextral movement along the fault zone) and a geological control (the brittle nature of the diorite unit) on mineralisation. The western diorite lodes vary in thickness from 1 to 5m and trend away from the Main Lode East at 185°.
Countess is hosted within tightly folded silica altered (“bleached”) diorite intrusions within an ultramafic sequence. The fold axis plunge steeply (70‐80°) to the south. Countess consists of 6 lodes (West, East, Alpha, Beta, Gamma and Tindals Deep). Alpha, Beta and Gamma Lodes are minor lodes and have only been defined in the latest round of drilling. The West Lode strikes 350° and dips 60°W, and has an average width of 3‐16m, while the East Lode strikes 005° and dips 65‐75°E, with widths of between 2‐6m. The Tindals Deep Lode strikes 000° and dips 80°W, with widths between 2‐7m. With the minor lodes Alpha and Beta Lodes both strike 020° and dip 80°E with average widths of 0.5‐6m, while the Gamma Lode strikes 350° and dips 80°W, with averages widths of 0.5‐ 4m. Mineralisation consists of quartz/sulphide micro‐veinlets, disseminated pyrrhotite and albitic alteration of the diorites. No visible gold has been seen at Countess.
The Empress deposit is hosted predominantly in two different trending graphitic shales (the Western Lode and the Empress Reef) which have been sheared and intruded by quartz/sulphide veining. The four mineralised zones within the two sheared graphitic shales make up the Main Lodes in the recent geological interpretation. The East–West mineralised graphitic shale (historically labelled the Western Lode) is within the basalt sequence and generally strikes 030° dipping steeply to the east (80° to 85°) with an average width of 0.5 to 5m. This mineralised trend is cross‐cut below 160mRL by a garnetiferous diorite intrusion. The diorite intrusion is within the basalt sequence and generally strikes 015° with an average width of 3 to 6.5m. The southern section of the diorite dips steeply to the west (80° to 85°), while the northern section of the diorite dips steeply to the east (80° to 85°). Mineralisation consists of quartz/sulphide micro‐veinlets and disseminated pyrrhotite. The Empress South and Empress North mineralised graphitic shale (historically labelled the Empress Reef) is within the ultramafic sequence and generally strikes 021° with an average width of 0.5 to 5.5m. The southern section of this mineralised trend dips steeply to the west (80° to 85°), while the northern section of this mineralised trend dips steeply to the east (80° to 85°). Movement along the 5 to 10m thick shear zones creating the Main Lodes has resulted in mineralisation along the numerous sub‐parallel graphitic shales in both the basalt and ultramafic sequences. The mineralisation in these parallel lodes is patchy can be traced between the Main Lodes and in some cases are modelled as splays running off the Main Lodes.
The Greenfields deposit is located within a Dolerite Sill. The deposit is divided into five geological units – Units 2, 3, 4 and 5 (of the dolerite sill) and volcaniclastic sediments of the Kurrawang Formation. The gold mineralisation tends to be associated with pyrite in the extensional veins, pyrrhotite in the wall rock as halo alteration and pyrrhotite in quartz veining within the dolerite sequence. The lodes strike 110° and dip 70°S with average widths of 10m.
The resource update at Perseverance is the result of drilling done in the March and September 2009 Quarters. The resource upgrade at Countess is a result of drilling done in the December 2008 Quarter and the extensional drilling done towards the end of the June 2009 Quarter. The resource upgrade at Empress is a result of drilling done in the March 2009 Quarter. The resource update at Greenfields is a result of a re‐interpretation and a review of the parameters used in the previous resource estimation.
The updated interpretations were then used to create new resource models for the deposits.
Drilling Information
The Perseverance Resource was calculated from a total of 282 diamond and 48 RC holes for a total of 43,407.12m. Drill spacing is generally 15m x 15m in the core of the resource, and this widens to 50m x 50m outside of this. The Countess Resource was calculated from a total of 203 Diamond holes for a total of 27,079m. Drill spacing is generally 25m x 25m in the indicated resource area, which widens to 40m x 40m in the inferred resource area. The Empress Resource was calculated from a total of 42 Diamond and 5 RC holes for a total of 8,134.02. The Greenfields Resource was calculated from a total of 56 diamond and 152 RC holes for a total of 18,322.1m. All drill collars for Perseverance, Countess and Empress have been surveyed in local Tindals Mine Grid co‐ ordinates. All drill collars at Greenfields were surveyed in the local mine grid in the area and have subsequently been converted to GDA94 co‐ordinates.
The drill holes at Perseverance, Countess, Empress and Greenfields have either been down hole surveyed by Eastman single‐shot camera, Reflex Ezi‐shot, electronic multi‐shot (EMS) or gyroscope methods. All drill holes that were surveyed at Perseverance, Countess and Empress were done so in Tindals Mine Grid coordinates, while at Greenfields the drill holes that were surveyed were done so in the local mine grid in the area and have subsequently been converted to GDA94 co‐ordinates.
All drilling has been logged (lithology, alteration, structure, veining and mineralisation) in detail and stored in electronic databases after been validated.

Diamond core is sampled to geological boundaries for the Focus drilling, and to a combination of geology or metre intervals for pre‐ Focus drilling. The core was cut in half, with only half submitted for assaying.
All samples (Focus and pre‐Focus drilling) have been assayed using the Fire Assay method at Analabs, ALS Chemex or Kalgoorlie Assay Laboratory in Kalgoorlie. For drilling since 2006 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. Check assaying of sample pulps and quarter core was conducted at Genalysis Laboratory in Perth for independent auditing of the assaying process.
Geological Model
The geological interpretation (geology and mineralisation) and the resource estimation were conducted internally. The mineralised interpretation at Perseverance, Countess and Empress was digitised to either geological boundaries or a nominal 1g/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 (<1g/t) have been included to allow for continuity of the interpretation. At Greenfields the mineralised interpretation was digitised to a nominal 0.5g/t cut‐off grade with no more than 2m of internal dilution allowed. All interpretations were 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 at Perseverance, Countess, Empress and Greenfields were composited to 1m intervals. The composites were used to determine the necessary top cuts. For Perseverance the top cuts used for the resource were 65g/t for the Main Lode East and East Lode Splays, 75g/t for the Sulphide Lodes, 48g/t for the Sherlaw Lodes, 65g/t for the South Diorite Lodes and 20g/t for the West Diorite and Linking Structure Lodes. For Countess the top cuts used for the resource were 20g/t for the West Lode, 12g/t for the East Lode, 8g/t for the Alpha Lode and 6g/t for the Gamma Lode. Due to the small amount of data in the Tindals Deep Lode an arbitrary value of 10g/t was selected. The Beta Lode only contained low grade and did not require a top cut. For Empress the tops cuts used where 40g/t for the Main and Diorite Lodes, and 45g/t for the Splay Lodes. At Greenfields three different domains were selected (Lode 1, Lode 11 and Minor Lode Domains) for the resource estimate. Lode 1 and 11 Domains host the majority of the mineralisation and occur within the Unit 4 Dolerite. They are parallel in orientation but have subtle geological differences with the Lode 11 Domain appearing less altered. Both display quartz veining with pyrite and pyrrhotite mineralisation. The grade in the Lode 11 Domain is less consistent. Top cuts for Lode 1 Domain was 15g/t and 10g/t was used for the Lode 11 Domain. The Minor Lodes Domain is a series of less continuous lodes that is a function of faulting in various orientations that occur within the Unit 4 and 5 dolerites. Mineralisation is mostly related to quartz veining with pyrite and pyrrhotite similar to the two larger Domains. A top cut of 20g/t was used for the Minor Lodes.
Surpac block models were created for Perseverance, Countess and Empress on the Tindals Mine Grid co‐ordinates, with the Greenfields block model created on a GDA94 grid. The models were generated using the Ordinary Kriging (OK) estimation method.
Different values for bulk density were applied to the various lodes at Perseverance based on test work. A density of 2.9t/m[3] was used for the sulphides lodes, 2.7t/m[3] was used for the Main Lode East and its Splay Lodes, 2.78t/m[3] was used for the West and South Diorite Lodes and a value of 2.8t/m[3] was used for the Sherlaw Lodes. Bulk density of 2.72t/m[3] was applied to the Countess model. For Empress a bulk density of 2.75t/m[3] was applied to the Diorite Lodes while 2.9t/m[3] was applied to the Main and Splay Lodes. These values were based on values determined from test work conducted on Perseverance, Countess and Empress drilling. For Greenfields bulk densities of 1.8, 2.4 and 2.8t/m[3] were used for the oxide, transitional and fresh zones respectively. These values at Greenfields were based on test work completed on 109 core samples, and compare well with values used historically for Greenfields.
The reported grades, tonnages and contained ounces are rounded to appropriate levels of precision in accordance with the recommendations of the JORC code.
Perseverance, Countess and Empress Resources have been reported at a 2g/t lower cut‐off grade, while the Greenfields Resource has been reported at a 1g/t lower cut‐off grade.

Note on Open Pit Reserve Estimates
All reserves are a subset of the reported resources, that is; the resources are not in addition to the ore reserves. Tables are subject to rounding of significant figures.
Greenfields
The Greenfields probable reserve estimate is based on the resource model tabled in the quarterly report. The reserves represent extensions to the existing pit along known mineralisation and at depth. The open pit extension design is considered to be practical, workable and safe.
Mining dilution of 10% at 0.00g/t and a mining recovery of 95% have been incorporated into the probable mining reserve estimate.
Big Blow
The Big Blow probable reserve estimate is based on the resource model tabled in the quarterly report. The reserves represent a small open pit, situated on and around some small historical underground workings. The open pit design is considered to be practical, workable and safe.
Mining dilution of 10% at 0.00g/t and a mining recovery of 95% have been incorporated into the probable mining reserve estimate.
Dreadnought North
The Dreadnought North probable reserve estimate is based on the resource model tabled in the quarterly report. The reserves represent a small, from surface open pit. The open pit design is considered to be practical, workable and safe.
This open pit will in addition to providing probable reserves, enable additional geological, mining and metallurgical information to be obtained for use in the assessment of the entire Dreadnought resource.
Mining dilution of 10% at 0.00g/t and a mining recovery of 95% have been incorporated into the probable mining reserve estimate.
