I am pleased to attach the September Quarter operating and cashflow report for Bass Metals Ltd (ASX:BSM).
The Company continues to perform well despite volatile and challenging market conditions due to its high grade mining operations and mineral assets, supported by prudent financial and risk management strategies. Bass Metals’ objective is to transform into a mid tier diversified mining and exploration company; primarily through the development of its robust high grade projects such as Que River, Hellyer Mine Project (HMP) and potentially high grade, polymetallic prospects such as Oonah, Magnet and Farrell, but also through acquisition and corporate transactions which together meet the key criteria of adding shareholder value.

The Company’s Que River mine is high grade and generated strong operating margins in the September quarter. The recently upgraded Mineral Resource inventory also has high grade polymetallic endowment, which the company is evaluating to bring into production. Underpinning this robust asset base is a strong cash position of approximately $7 million at the date of this report.
The Board considers that based on current cash flow forecasts, work budgets and positive ore reconciliation trends that the Company is well positioned over the next 12 to 18 months to achieve its core objectives of advancing the HMP to a decision to mine, progressing its regional advanced high grade projects and continuing to follow-up on selected earlier stage targets with potential for a major mineral discovery whilst accumulating cash, subject of course to the outcome of feasibility studies and prevailing market conditions. While challenging, the current adverse equity and metal market conditions are generating new corporate and project opportunities and the Board continues to review these on both technical and financial merits and always with the key criterion of returns to shareholders.
Bass Metals has a strong cash position and robust mineral assets which should see it well positioned to benefit from any recovery in metals markets in the near to medium term. I look forward to providing further updates on our progress in these activities.
Yours sincerely

SEPTEMBER 2008 QUARTERLY ACTIVITIES REPORT
A. BASE METALS
A1.0 Mine Operations – Que River
A1.1 SAFETY & ENVIRONMENT
No lost time injuries have occurred during the Quarter or since the start of the project. There were several minor discharges of untreated run-off water from the settlement dam due to exceptionally heavy rainfall during the period.
A1.2 MINING ACTIVITIES
Mined tonnages of ore in the September Quarter exceeded predictions from the Ore Body model by 283% ( refer Table 1 ). Actual mined grades for zinc, lead and copper exceeded predictions with silver and gold grades down marginally.
The project to date reconciliation of mined versus predicted tonnages is strongly positive with a greater ore contribution from the PQ pit. All metal grades are significantly higher than predicted.

A1.4 OPERATING PERFORMANCE
Revenues
Revenue for ore sold during the September Quarter is estimated to be $6.2 million. This amount does not include hedging gains associated with ore sold.
Cash flow receipts for the quarter were $3.6m.
After correcting for minor moisture content, ore tonnes sold were 17,876 dry metric tonnes (dmt) which yields gross revenue of $345/dmt sold. Revenue quoted above is based on actual tonnes delivered and invoiced. Revenue estimates and eventual cash flows are affected by the time lag between delivery of the sold ore and fixing the realised price ( the Quotational Period ); for zinc and lead this time lag is three months, for gold and silver one month and for copper six months.
Hedging gains associated with ore sold during the Quarter are estimated at $0.6 million resulting in a total estimated value of ore sold for the quarter of $6.8 million or $373/dmt.
Costs
A summary of operating costs for the Quarter is presented in Table 3 below. The cost calculation is based on all operating costs, including mining, treatment, haulage, royalties, depreciation and amortisation of mine properties but excludes capitalised mine development for the Quarter consistent with the Company’s accounting policies as detailed in the 30 June 2008 annual report. The difference between “sold” and “mined” unit cost reflects the closing inventory position.
Table 3: Unit Operating Costs
Unit Cost basis |
Unit |
Sept 08 Qtr | June 08 Qtr |
|---|---|---|---|
| Ore sold | $/dmt | 236 | 238 |
| OreMined | $/wmt | 222 | 229 |
Total capital costs at Que River for the Quarter were $0.03 million, bringing the project to date expenditure to $0.63 million, which is in line with the Stage 1 Mine Plan.
Operating Margin
To monitor and manage the financial performance of the project; i.e. the margin between cash costs and revenues, the Company also prepares management reports to determine the net realisable value (NRV) and operating margin of ore mined. The reports include adjustments to the Company’s accounting policies for the following:
Revenue
- Adds the expected revenues from the stockpiles to those from ore already sold and delivered in the period.
Costs
-
Collation of all of the costs incurred during a period, with no accounting adjustments for depreciation and amortisation of mine properties or capitalising of mine development.
-
Addition of expected costs to realise value from the stockpile inventory - namely haulage, treatment charges and royalties.

A2.0 Base Metal Exploration Activities
A2.1 ADVANCED PROJECTS
The Company has an exciting profile of advanced polymetallic prospects to underpin its growth prospects. A particularly attractive feature of all of the prospects is the high base and precious metal grades.
A2.1.1 Q ue River
There is significant exploration potential at Que River in the vicinity of the current shallow resources and also to the south and at depth. The Company has shallow, potentially open pitable resources at the QR32 and Nico lenses that it is seeking approval from Mineral Resources Tasmania (MRT) to mine and which have the potential to increase the mine life at Que River. Further drilling of targets is planned in the December Quarter 2008.
A2.1.2 Hellyer Mine Project (HMP)
The HMP was the core focus for the Company during the September Quarter. Completion of the Fossey resource estimate (refer Table 5) has increased the overall resource base to 1.6 million tonnes at HMP and the overall HMP-Que River JORC compliant resource to 2.3 million tonnes of high grade polymetallic mineralisation as summarised in Table 6. Fossey Zone is an exciting new high grade prospect immediately south of the Hellyer mine development, that is open at depth and to the south as shown in shown in Figure 3. (Reported to ASX 30 September 2008 and 26 October 2007)
The HMP (Fossey & Hellyer Resource) activity focus has been:
-
Drill out and extend the Fossey Zone – a further 13 drill-holes were completed, with two in progress, for a total of 3,029.8 metres in the Quarter.
-
Continuation of the Mining Study comprising, resource assessment, mining studies, environmental studies and metallurgical test work.
-
Appointment of a full-time Hellyer Mine Project Study Manager.
Fossey Zone Resource
MacArthur Ore Deposit Assessments Pty Ltd (MODA) was commissioned by Bass Metals to undertake a mineral resource estimate for the mineralisation at the Fossey Zone, which is fully reported in accordance with the JORC Code in a report to ASX on 30 September 2008. The resource estimated at a 5% (Pb+Zn) assay cut-off is summarised in Table 5 below.
The resource model comprises three main mineralised domains; a base metal sulphide zone, massive barite zone and a footwall stringer vein zone. A minor zone of gold-rich siliceous pyritic mineralisation was also included on the western side of the barite lens.
In addition to the base metal mineralisation the large barite body holds significant gold and silver grades. Combined Mineral Resources based on a 1g/t gold cut-off were estimated to be 2.5 million tonnes at 1.9 g/t gold and 66 g/t silver, which suggests that there may be scope for a larger scale mining and processing scenario.
The methodology utilising a relatively high, 5% (Pb+Zn) cut-off, is regarded as conservative and ensures a focus on grade rather than tonnes and contained metals. The Indicated Mineral Resource has consistently higher grades than the Inferred Mineral Resources, which is a positive trend as significant BMS mineralisation has been intersected in current infill drilling.

Fossey Zone Exploration
Drilling at the Fossey Zone is targeting the along strike and down dip extensions of high grade massive sulphide intersected previously and has continued at an accelerated rate during the Quarter. The Phase One drilling program at 50 metre section spacing, designed to extend and define the mineralised zone was completed early in the Quarter and immediately followed-up with the Phase 2, infill drilling programme on 25 metre spaced sections; this work is ongoing.
A summary table of drill-hole locations, completed during the period is shown in Table 7 and a schematic long projection in Figure 4.
Figure 3: HMP Schematic Long Section
==> picture [484 x 333] intentionally omitted <==
Drilling results generally continue to be positive, confirming the interpretation of a large wedge of mineralised barite hosting several zones of massive high-grade base metal sulphide and an underlying BMS stringer envelope.
Highlights of assay results for the Quarter presented in Table 8 include:
-
HLD970 - 13.4 metres at 4.6 g/t Au and 33 g/t Ag;
-
HLD971 - 9.2 metres at 20.8 % Zn, 8.8 % Pb, 0.9 % Cu, 290 g/t Ag and 3.0 g/t Au;
-
HLD972 - 8.15 metres at 2.0 g/t Au and 36 g/t Ag; and,
-
HLD982 - 24.1 metres at 11.7 % Zn, 3.9 % Pb, 95 g/t Ag and 3.1 g/t Au.
Drilling to date at Fossey has confirmed a moderate southerly plunge to the system and the geological interpretation evolving remains consistent with that reported previously and shown in Figure 3. The infill drilling has confirmed the continuation of high grade mineralisation on the 10125mN and 10175mN drill cross sections.

HMP Mining Study
The HMP Mining Study continued through the Quarter; key updates not already covered are summarised below:
-
(i) Mining Assessment
-
Mancala Pty Ltd and Bass Metals have agreed in principle to extend the current Que River Mining Alliance Agreement, in general terms to include the HMP. The Mancala executives have direct mining and operational experience at both the historic Que River and Hellyer Mine sites and contribute a significant technical legacy to the HMP study. With the recent completion of the initial Fossey Mineral Resource estimate Mancala has commenced assessment of the underground access and mining options.
-
(ii) Metallurgy- Fossey Zone
-
Initial impressions of the samples studied to date indicate enhanced metallurgical properties compared with the “average” adjacent Hellyer Mine ore, processed from 1987 to 2000:
-
Galena (Pb sulphide) and sphalerite (Zn sulphide) are coarser
-
chalcopyrite and tetrahedrite (Cu sulphides) are finer
-
sphalerite/galena association is much finer with some fine sphalerite in galena
-
sphalerite/pyrite association is much lower
-
galena/pyrite association is much lower
-
little arsenopyrite was observed.

Metallurgical test work on 12 samples of Fossey Zone material is currently carried out at the Burnie Research Laboratory (BRL) where members of staff have particular competence in the mineral processing of polymetallic ore from volcanogenic massive sulphide deposits.
BRL personnel have had a long involvement with flow sheet development and operation of the Hellyer concentrator up to 2000. The work is being supervised for Bass Metals by Peter Munro, principal consulting engineer of Mineralurgy Pty Ltd.
The preferred treatment route for this material is sequential flotation of copper (plus precious metals), lead and zinc with minimal production of bulk concentrate to maximise the realisable value.
Tests to date have given the following results:
-
copper flotation gave 70-80% copper recovery with cleaning upgrading to a copper concentrate grade of 11.3% Cu at 60% recovery with high gold and silver values;
-
lead roughing produced 25-40% Pb grades at 80-90% recovery which is a good lead performance compared with the former Hellyer operation. Cleaner flotation made a high grade concentrate of 59% Pb at 65% lead recovery; and,
-
zinc roughing produced 35-40% Zn grades at 50-70% recovery with some zinc losses to the lead section due to the high lead:zinc head ratio. The best test made a 55% Zn concentrate at ~70% zinc recovery.
BRL’s work has focussed on rougher flotation to determine appropriate metallurgical domains. These results are regarded as very encouraging because the testwork involved:
-
50µm primary grind for rougher flotation;
-
no regrinding of any contrite products;
-
one stage of copper cleaning, 2 stages of lead cleaning, 2 x stages of zinc cleaning.
It must be pointed out that these results are preliminary only and are likely to understate what would be achievable in a production plant. The tests:
-
do not include regrinding which can be expected to reduce the misplacement of values to other concentrates;
-
are open circuit which usually lowers recovery;
-
do not include producing a bulk zinc-lead concentrate which is an inferior product, but enables higher metal recoveries by collecting the finer grained Pb-Zn intergrowths; and
-
confirmed MODA’s mineralogical observations and the likely enhanced processing attributes of the ore.
The Fossey Zone includes significant barite-gold-silver mineralisation. Several rougher flotation tests have been done on this auriferous barite material showing significant upgrading at high gold recoveries. The potential to create a gold concentrate for further processing by conventional means is also being investigated.

A2.4 REGIONAL BASE METALS EXPLORATION
Highlights of limited regional style exploration work carried our during the winter period includes
Magnet Mine - Waratah (EL64/2004)
(Bass Metals Ltd 75% & Clancy Exploration Limited 25%)
The drill-program postponed earlier in 2008 due to drilling issues is scheduled to recommence in mid-October, 2008.
The program will test the near surface potential of the historic high-grade Magnet Lead-Silver (Zinc) mine. The program comprises 8 diamond drill holes for approximately 1,000 metres.
North Rosebery (EL54/2004)
(Bass Metals Ltd 75% & Clancy Exploration Limited 25%)
The 375 sample (8.5 line km) North Rosebery partial digest soil survey was completed during the Quarter. The survey covers prospective stratigraphy north along strike from the Rosebery Mine sequence. Assays are pending.
Oonah (EL63/2004)
(Bass Metals Ltd 75% & Clancy Exploration Limited 25%)
Work during the September Quarter was focussed on the historic Montana mining centre, namely planning and execution of the costean programme and the design of a first-pass reverse circulation drill programme to test for five parallel lodes structures reported of which four are unmined.
The Montana Mine is located approximately 5km northwest of the town of Zeehan and was mined in the late 1950’s. The main ore shoot comprised massive galena veining and was approximately 60 metres in strike-length and 7-8 metres at its widest point. Stoping of the lode reached a depth of 60 metres below surface and historical records of mine sampling indicate significant high grades of silver and lead mineralisation:
-
9.3 oz./t Ag, 13.5 % Pb & 1.0 % Zn
-
15.7 oz./t Ag, 7.4 % Pb & 1.2 % Zn, and
-
14.5 oz./t Ag, 10.4 % Pb & 1.7 % Zn.
Mining activities at Montana, as with other mines of this era such as Magnet (Waratah EL) and Farrell (Tullah EL) avoided the zinc rich mineralisation as it was considered a contaminant to lead smelting operations. As such, the zinc potential of the area is unrealised and no drilling has occurred in the vicinity of the mine.
Recent work by Bass Metals has included:
-
Four costeans – to intersect near surface lodes for a total length of 180 metres.
-
One costean (Number 3), intersected approximately 5 metres of visible (and interpreted as high grade) lead-zinc and copper sulphide mineralisation. Another interval, 1 metre wide of visible mineralisation was also logged at the northern end of this costean, approximately 15 metres from the interval above.
-
Channel sampling is in progress and assays are pending.

Wilmot (EL51/2004)
(Bass Metals Ltd 75% & Clancy Exploration Limited 25%)
A grid was established for a ground EM survey to follow-up on anomalies generated by the airbourne VTEM survey reported previously. The ground EM programme is planned to be completed in the December 2008 Quarter.
A2.4.1 Oz Minerals Hellyer Exploration Alliance (HEA)
(Oz Minerals earning 70%)
Oz Minerals (formerly Zinifex Australia Limited) has 4 Special Project Joint Venture (SPJV) areas, mainly on the Hellyer Mine Lease. They cover prospective portions of the Hellyer-Que River stratigraphy and include the promising early stage Switchback prospect where strong alteration and anomalous base metal sulphides were intersected during the initial phase of exploration drilling in 2007.
During the September Quarter Oz Minerals drilled a second hole (MS-2) at the Highpoint prospect to a depth of 1,156 metres. The hole was designed to test for a Hellyer-Que River style deposit. No significant mineralisation was intersected, downgrading the exploration potential of the High Point SPJVA, though Downhole-EM is scheduled to be conducted on this drill-hole in November, 2008.
B. GOLD
The Company continued low level work on its Mt Charter gold Mineral Resource and the Sterling Valley gold project. Further drilling and evaluation work is planned.
C. NICKEL & OTHER METALS
C.1 Heazlewood (EL31/2003) (Ni-Cu-PGM potential)
(Bass Metals Ltd 70% & Pioneer Nickel Limited 30%)
The work programmes planned for the Heazlewood nickel prospects have been delayed due to the requirement to complete certain floral studies to facilitate the permit process. Those permits have now been granted and drilling work is now scheduled for early next year. Further ground based geophysical surveys on other target areas will be undertaken in the December Quarter.
C.2 Venture Minerals Iron-Tin-Tungsten Joint Venture
Bass Metals and Venture Minerals Limited (VMS) executed a binding Heads of Agreement that set out the terms under which VMS has the right to earn up to 70% of any Fe, Sn or W projects that VMS generates on BSM’s Heazlewood and Whyte River tenements.
VMS considers the Heazlewood (EL31/2003) and Whyte River (EL36/2003) exploration licences are prospective for magnetite skarn type mineralisation. Bass Metals’ work on these licences, particularly the Heazlewood licence has focussed on nickel and gold, consistent with its strategy of exploring and developing high grade base and precious metals deposits. The Heazlewood licence hosts several promising nickel targets which BSM plans to drill test which are not part of this Joint Venture. The Whyte River tenement has a known iron-magnetite occurrence with re-assaying of a historic drill-hole providing results of 44.1% iron over 5.6 metres.
