2. 0 TEXAS SILVER MINES PTY LTD The Texas Project (EPMs 8854, 11455, and 12858; ML 5932 and ML 50161) is located 100km west of Stanthorpe. Texas Silver Mines Pty Ltd is a wholly owned subsidiary of Macmin Silver Ltd. 2.1 Twin Hills (ML 50161) - Development & Production Activities Summary 2.1.3 Commissioning of the first module of Merrill Crowe silver extraction capacity commenced and a sample of product has been sent for analysis to determine the required operating parameters and to provide information for marketing. 2.1.4 Loading of the initial leach pad area was completed and it contains 240,000 tonnes of crushed ore. Stacking commenced on the next leach pad which will hold approximately twice that amount of ore. Plans for the third pad area (southern extension of Pad 2), were prepared and earthworks will commence in August. 2.1.5 Electrowinning The mine production statistics for the quarter are as follows:
A total of 265,000 tonnes was mined as follows:
Fiscal year to date mining figures were incorrectly included in the previous quarterly report instead of figures for the quarter. The correct mining figures for March quarter are shown above. There is approximately 100,000 tonnes of ore on the stockpile ready for crushing. 3.0 CURRENT UPDATE 3.1 Crushing It is now expected that the upgraded circuit will commence operation during August and the impact of additional crushing capacity should effect silver production from October. 3.2 Silver Sales 4.0 EXPLORATION 4.1 Mt Gunyan Prospect Macmin Silver Ltd has recently received assay results for 4 drill holes of our on going drilling programme at Mt Gunyan, which commenced last year. The Mt Gunyan prospect is situated within 3km of the Twin Hills Silver mine, near Texas in SE QLD. Diamond drilling on the western flank of the Mt Gunyan prospect has improved the western bulk tonnage mineralisation and extended the higher grade northern pod. Highlights of the drill holes are as follows: MGD017 6m (70-76m) @ 103g/t Ag and 0.12%Zn MGD022 20.35 (6.25-26.6m) @ 102/t Ag, The mineralisation in MGD022 has extended the higher grade Northern Pod to the south 40m. MGD017 has bolstered the lower grade bulk tonnage mineralisation with an intercept of 20.35m @ 102g/t Ag, while MGD018 has restricted this mineralisation to the south-west. TABLE 1 – Drill Results
TABLE 2 – Hole locations for Table 1 data
Sampling & Assaying Details Sampling of percussion holes was undertaken over the full length of each hole on a 2 metre interval basis. Sampling of Diamond Core was undertaken over mineralised and altered zones, sample intervals were determined from geological intervals. In broad zones of alteration 2 metre intervals were selected. As part of the Company’s quality control programme, a duplicate sample is collected about every 20 samples and submitted under a different sample number providing a check on repeatability. Assaying is carried out by ALS Chemex in Brisbane using the ICP technique for silver, copper, lead, zinc, arsenic and antimony. Gold is assayed by the ICPMS technique. Drill holes Collars have been located with a hand-held Garmin GPS unit. Down hole surveys are recorded with an Eastman style single shot camera. 4.2 Tally Ho Prospect An initial Inferred Mineral Resource for the Tally Ho Prospect has been estimated at 733,000 tonnes at 49g/t silver, 0.06g/t gold, 0.1% copper, 0.09% lead and 0.83% zinc. Approximately 1,500m of the current Reverse Circulation drill program of 3,000m including 28 holes is completed. This program is intended to test adjacent prospective areas to the above mineral Resource with the objective of increasing the Resource. The attached ASX Release of 28th July provides an update on the Tally Ho ProspectDrill Sampling & Assaying Details Sampling of percussion holes was undertaken over the full length of each hole on a 2 metre interval basis. Sampling of Diamond Core was undertaken over mineralised and altered zones, sample intervals were determined from geological intervals. In broad zones of alteration 2 metre intervals were selected.

Drill holes Collars have been located with a hand-held Garmin GPS unit. Down hole surveys are recorded with an Eastman style single shot camera. Stream, Soil & Rock Sampling & Assaying Details Stream sediment samples consist of approximately 100g of 180µm collected from the fine silt fraction of the active drainage. Assaying is carried out by ALS Chemex in Brisbane using an aqua regia digest which is analysed with the ICP technique for silver, copper, lead, zinc, arsenic and antimony and analysed by the ICPMS technique for Gold. 5.0 CORPORATE The Company has exercised its right to make the first repayment of US$1.5M in respect of the Convertible note loan by the issue of shares in five tranches. The repayment due date was 5 May 2008 and a total of 2,647,375 shares were issued in the quarter to 30 June, representing a repayment of US$300,000 (AUD$321,251). A further US$300,000 was repaid after the end of the quarter by the issue of shares in July. 6.0 INVESTMENTS Macmin maintains equity investments in the following public companies with exposure to the precious and base metals sectors.
