1.0 SUMMARY & COMMENTS
Macmin Silver Ltd (Macmin) is a silver focused company whose primary projects are the Texas Silver Project, S.E. Queensland, Australia where the Twin Hills Silver Mine is nearing production and the Tally Ho Project near Mackay, Central Queensland. Macmin has exposure to gold by way of a 15% equity in New Guinea Gold Corporation (NGG) and a 1% NSR royalty on production by NGG. In addition, Macmin maintains equity investments in junior Australian explorers, Malachite Resources NL and Frontier Resources Ltd.
  • Production of first silver powder from the Twin Hills Silver Mine achieved during commissioning of the project.
  • Drilling commenced at Mt Gunyan to upgrade and locate further silver resources, within 2km of Twin Hills Silver Mine.
  • Drilling programme underway at Tally Ho silver project near Mackay in Central Queensland.
  • New Guinea Gold commenced gold processing at the Sinivit Mine in April with first gold pour expected in May 2007.
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/Commissioning Activities Summary

The Company produced the first silver powder from the Twin Hills Silver Mine on March 30, 2007.

This initial production resulted from commissioning of the plant, which saw the passage of mine ore through the entire mining and production circuit, including the Electrometals silver extraction electrowinning circuit, to finished product. Production of silver powder will gradually increase over the next 3 to 6 months to an annualised rate of 2.5 million ounces of silver.
  • We have received the non-standard Environmental Authority (EA) conditions from the Environmental Protection Agency (EPA) and we have agreed in writing to those conditions. We await final documentation from the EPA. Mining, crushing, stacking, leaching and silver production is continuing.
  • The following mining statistics mainly refer to the first quarter of 2007, although mining did start during the last quarter of 2006.

Total to date
High Grade Ore (>40g/t silver)
39,748 tonnes
Low Grade Ore (20-40g/t silver)
7,365 tonnes
Waste
102,314 tonnes
  • Processing provided 34,152 net tonnes of crushed, agglomerated and stacked ore, which has been placed on the leach pad.
  • Late in the quarter leaching commenced on 20,000 tonnes of agglomerated product. A small quantity of silver pregnant liquid was used to commission part of the electrowinning circuit producing silver powder.
  • Management will continue to optimise processes and equipment utilisation as the mine workforce gains experience and production levels are built up.
3.0 EXPLORATION
3.1 Tally Ho Silver Project
Cultural Heritage clearance and drill track construction was undertaken in preparation for drilling which commenced in April.

The programme of 5,000m of drilling follows on from the highly successful drilling in 2006 which encountered a broad zone of breccia hosted silver-zinc polymetallic mineralisation.

The Company believes that a major zone of mineralisation associated with the top of an intrusive complex is being revealed by the drilling.

Assay results from this programme should start becoming available during the second quarter.

Correction:

3.2 Mt Gunyan, Texas Project

Drilling commenced at the end of the quarter on the Mt Gunyan prospect (ASX Release: Exploration Update 15 March 2007). The aim of the programme is to add to the current resource base by testing for depth extensions and strike extensions to the known silver mineralised zones. Should sufficient resources be delineated, an application for a mining lease will be made and a Feasibility Study to evaluate its commercial development will be undertaken.

The initial assays from the programme will become available during the second quarter.

3.3 Macmin - Malachite Joint Venture: Boonoo Boonoo and Rivertree

Malachite Resources NL advised Macmin during the quarter that it will contribute to ongoing exploration in order to maintain its 25% interest in the Boonoo Boonoo joint venture.

Results were received from a programme of 331m of drilling at the Star of Hope lode and the Specimen Gully lode. The best intercept at the Star of Hope lode was encountered in hole BBD002: 4.25m @ 0.89g/t gold and 38.7g/t silver from 36m downhole. This hole was following up an earlier intercept by Malachite which encountered 1m @ 7.15g/t gold and 256g/t silver from 31m.

Six drill holes at the Specimen Gully lode encountered low order geochemical values with the best result being 1m @ 0.24g/t gold and 0.5g/t silver from 8m in hole BBP029. These holes were drilled using the open hole percussion technique, and as water was encountered at very shallow depths thus stopping the drilling, the lode is not considered to have been adequately tested.

An exploration programme for the Rivertree and Boonoo Boonoo tenements is being formulated by Macmin for the remainder of 2007, for approval by the joint venture parties.

All releases to the ASX can be viewed on the Macmin website, www.macmin.com.au. However, some of the more important releases this quarter are included in this report at Appendix A.

MACMIN SILVER - ASX RELEASES

2nd March 2007
TWIN HILLS SILVER MINE UPDATE

  • John Magnussen has accepted the position of Mine Manager (and Site Senior Executive) at Twin Hills with the appointment to commence on March 19. John is a Mining Engineer and has many years experience in senior mine management positions throughout Australia. We warmly welcome him to Macmin.
  • During the month, a total of 60,000 tonnes of waste was removed from the top 5m of the Twin Hills pit. The removal of this waste will provide a large work area in the pit to access the silver ore. The waste was dumped into the waste rock dump where an ‘under drain' (to minimise any potential acid leachate emerging from the waste dump after rainfall events) was recently completed.
  • Staff from Electrometal Technologies Ltd are on site finalising piping and electrical work in readiness for wet commissioning (water only) of the total electro-winning circuit next week.
  • Leachate irrigation will commence on March 5th over the initial heap of 20,000 tonnes of crushed and agglomerated ore. It is estimated that the solutions will take two to three weeks to saturate the heap prior to flowing into the processing pond. Once sufficient volume is present in the processing pond, it will be pumped through the electro-winning circuit to commission the plant and initiate production of silver powder.
  • It is anticipated silver powder production will commence towards the end of March. Ramp up of mining, crushing and stacking leaching and silver production will then follow, progressively leading to full production of 2.5 million ounces of silver per annum.

A brochure detailing the status of the Twin Hills Silver Mine commissioning is currently on the website and I would encourage all interested shareholders and investors to view the brochure and see the progress achieved to-date.

Yours faithfully

15 March 2007
EXPLORATION UPDATE
  • TEXAS PROJECT

    - MT GUNYAN
    Mt Gunyan forms a topographic feature rising over 100 metres above the surrounding countryside and is situated 3 km north from the Twin Hills Silver Mine. Exploration to-date by Macmin has shown that the Mt Gunyan area hosts a number of metal associations including silver, silver-gold, gold and silver-copper.

    A percussion drilling programme carried out in 2003 by Macmin on Mt Gunyan identified an Indicated Resource of 2.1 million tonnes at 68g/t silver equivalent. This resource included a higher grade zone of 452,000 tonnes at 175g/t silver equivalent (60g/t cut-off) (refer page 2). At the time, the low price of silver did not encourage the Company to persist with further exploration and so drilling was discontinued.

    With the upward movement of the silver price in the last three years, the Company believes it is now the right time to re-evaluate the Mt Gunyan area. Consequently, a major drilling programme will commence in April with the aim of adding to the current resource base. Percussion and diamond drilling will test for depth extensions to the known silver mineralised zones in addition to seeking out strike extensions. Should sufficient resources be delineated, an application for a mining lease will be made and a Feasibility Study to evaluate its commercial development will be undertaken. In addition, drilling will also be carried out at the Mt Gunyan South East Silver Prospect (1.5 km south-east of Mt Gunyan) where Macmin undertook a 12 hole shallow percussion programme in 2001. All drill holes intersected anomalous silver values (3-136g/t silver) at shallow depths in silicified rock types similar to the Twin Hills silver deposit (refer page 3). The likelihood of this silver mineralisation having similar metallurgical characteristics to the heap leachable Twin Hills silver deposit makes it an important target for further drill testing.

    - RIG PURCHASE

    Macmin will take delivery in April of a purpose designed diamond drilling rig to complement the existing Investigator Mark IV percussion/diamond rig which the Company owns.

    Both rigs will be utilised on the Mt Gunyan drilling programme described above. The Company has identified that drilling rigs, manned by our own staff, provide us with the added flexibility - in a highly competitive market for contract drilling - of getting drilling jobs carried out in our own timeframes. We are fortunate in retaining the services of Mr Roger Hall (a major shareholder in Macmin) as drilling supervisor to oversee maintenance and training for our drill crews.
  • TALLY HO PROJECT

    Since acquiring the Tally Ho Silver Project in mid-2006, which had not previously been drill tested, Macmin has had significant success in defining breccia hosted silver zinc polymetallic mineralisation.
    A total of 35 holes were completed in 2006 with potentially economic intercepts of silver and polymetallic mineralisation encountered in many holes; investors and shareholders are referred to previous ASX announcements.

    Assay results were recently received from 2 diamond drill holes, which were completed at the end of the programme in 2006. The holes encountered breccia hosted mineralisation deeper than previously drilled and Table 1 shows a list of the better intercepts encountered.

    In addition to intersecting significant silver-polymetallic mineralisation (5m @ 641g/t silver equivalent and 7m at 280g/t silver equivalent in GRDD2) both holes encountered narrow widths of high grade ("bonanza style") gold-silver mineralisation.

    In GRDD1 - 1 metre at 3.34g/t gold and 1,010g/t silver was encountered between 170 and 171m downhole; in GRDD2 - 1 metre at 133g/t silver and 12.25g/t gold was intersected between 110 and 111 metres downhole.

    Thus, the drilling continues to demonstrate that the breccia zones are capable of hosting a number of metal associations which the Company believes highlights the prospectivity of the Tally Ho area.

    A multi-purpose rig (reverse circulation and diamond capabilities) has been contracted to start a major drilling programme in April. The aim of the programme is to define the resource at Tally Ho and to look for continuation and extensions to the mineralised zones encountered to-date.
  • MACMIN-MALACHITE JOINT VENTURE

    The Macmin-Malachite Joint Venture covers two exploration licences in northern New South Wales, namely Boonoo Boonoo and Rivertree. Since inception of the Joint Venture in 2005, Macmin has sole funded exploration to earn a 75% interest in these tenements owned by Malachite. Results of this exploration can be seen in previous ASX announcements.

    In January 2007, Malachite advised that pursuant to the Joint Venture Agreement, it will contribute pro-rata to ongoing exploration in order to maintain its 25% interest in the Joint Venture. A management committee will now be formed and an exploration programme formulated for the remainder of 2007.

    Macmin welcomes Malachite's commitment to the Joint Venture funding and believes that the technical expertise from both companies will enhance the chance of exploration success on the projects.

SILVER PRODUCTION

Macmin Silver is pleased to announce that the first production of silver powder from the Twin Hills Silver Mine at Texas, Queensland was achieved on 30th March 2007.

This milestone completes the passage of mine ore through the entire mining and production circuit, including the Electrometals silver extraction electrowinning plant, to finished product. Production of silver powder will gradually increase over the next 3 to 6 months to an annualised rate of 2.5 million ounces of silver. If, at that time, market conditions are appropriate, Macmin will consider a further gradual increase in annualised production to approximately 4 million ounces of silver.

The strategy of producing a silver powder and seeking direct sale of the powder is aimed at lower production costs, elimination of refining costs and potentially obtaining a premium price for this unique form of silver. Silver powder is used in a number of industrial situations such as electronics and antibacterial applications and is usually obtained by breaking down silver ingots.

Supplying the powder as a mine gate product will be the subject of substantial marketing initiatives as production increases. Any silver powder production which does not find an immediate market can be readily refined and sold in solid form.

In respect to the Non-Standard Environmental Authority (EA) in our ASX release dated 5th March 2007 we note that we have now received the EA conditions from the Environmental Protection Agency (EPA) and have agreed in writing to those conditions. We await receipt of final documentation from the EPA. Mining, crushing, stacking, leaching and silver production is continuing.

Management will continue to optimise processes and equipment utilisation as the mine workforce gains experience and production levels are built up.

The Board would like to take this opportunity to thank staff, shareholders, suppliers and contractors for their support during the mine construction phase and into the future as the mine develops.

Yours faithfully,
MACMIN SILVER LTD

NEW GUINEA GOLD CORPORATION - TSX RELEASES

21 February, 2007
NEWS RELEASE

3m at 180g/t GOLD (6 ozs) within 24m at 33.7g/t GOLD in TRENCH at MT PENCK

Vancouver, February 21st 2007. Recent trenching at the Mt Penck Project in Papua New Guinea has confirmed two significant new gold mineralised zones at Upper Peni Creek and Kavola South. Upper Peni Creek is 300m west of Kavola East, where most of the 2006 drilling was concentrated, and Kavola South is 100m south of Kavola East. The trenches are hand dug trenches and were dug to gain some idea of the lateral extent of gold grades along strike. The trenches were dug approximately parallel to the strike of the high grade "core" of both zones.

The Mt Penck Property is beneficially owned 60% New Guinea Gold and 40% Vangold Resources.

Upper Peni Creek Zone

Separate trench intersections above 0.5g/t gold cutoff include:

24m at 33.7g/t gold, including 12m at 62.93g/t gold, including 3m at 180g/t gold
12m at 4.07g/t gold
33m at 1.73g/t gold
18m at 1.82g/t gold
12m at 0.88g/t gold

Check assays of some sample pulps have been carried out that confirm gold values. Additional checks of the sample preparation rejects are now in progress.

The above results indicate an average grade for all samples above 0.5g/t gold cutoff of 9.68g/t gold. The average grade for all samples is 8.66g/t gold.

Upper Peni Creek was initially discovered in 2005 by surface channel sampling of outcropping siliceous vein/breccia that returned historical assay results of 1m at 38.2g/t gold (see press release dated 18 November 2006). However, the result was not followed up at the time and the zone was not recognized as a new target until late 2006.

Two initial scout holes, MPD 036 and MPD 037, were drilled in late 2006, before the trench results were available. MPD036 intersected 4m at 5.71g/t gold from 22m to 26m downhole, including 1m at 13.3g/t gold, 120g/t silver and 0.17% copper. This hole was drilled below the historic chip sample of 1m at 38.2g/t gold. Hole MPD037 intersected four 1m to 2m intervals grading up to 2.85g/t gold and 24.3g/t silver to a depth of 68m downhole. All results above a 0.5g/t gold cut off are listed in the table below.

Kavola South Zone

Separate trench intersections above 0.5g/t gold cutoff include:

30m at 4.42g/t gold
48m at 4.01g/t gold
24m at 2.82g/t gold
12m at 1.49g/t gold

The nearest drill hole to the Kavola South Zone is MPD 038 located 160m to the east. This hole intersected 4m at 1.13g/t gold from 44m to 48m downhole.

Mr McNeil CEO of NGG commented: "These are exciting trench results and the 3m at 180g/t gold represents the highest grades ever encountered at Mt Penck.The Peni Creek and Kavola South Zones appear to be separate mineralised zones from Kavola East, and the grades in trench make these highly attractive drill targets. At this stage the lateral and strike extent of both zones are unknown but surface observations suggest the very high grade zones have restricted widths of approximately one metre".

Kavola East Zone

Final assay results from the 2007 drilling program have now been received for holes MPD 030, 034 and 035. Scattered intersections over 1m to 2m intervals are present in MPD 030 and 034 to depths of 132 metres downhole. The best intersection was 1m at 3.34g/t gold, 10.3g/t silver and 0.33% copper from 88m to 89m downhole in MPD 034. Hole MPD 035 was drilled to the west outside the main Kavola East Zone and confirms that the Kavola East mineralisation is probably terminated by a fault along it's western side.

It should be noted that only about 30% of the total geochemically anomalous area at Mt Penck has been tested by drilling. All drill results above a 0.5g/t gold cut off are listed in the following table.

MOUNT NAKRU PROJECT


Assay results for three shallow holes at Mt Nakru, EL 1043, West New Britain Province, Papua New Guinea have now been received. NAK 010, 011 and 012 were drilled to a maximum depth of 76.5m downhole in late 2006 to test for near-surface gold mineralisation beneath a trench intersection of 55m grading 4.79g/t gold, including 15m at 16.01g/t gold (see press release dated March 27, 2006). Because of terrain limitations, the holes were collared 35 metres from the trench intersection and were designed to intersect the mineralised zone at depths of 30-50m. No zones above 0.5g/t gold were intersected in any of the holes.

Narrow 1m to 2m intersections of plus 0.1% copper were present in all three holes, up to 1m at 0.4% copper in NAK 010 at 73m downhole. The zone is now being re-assessed to attempt to explain the lack of gold in the drill holes.

The Mt Nakru Property is beneficially owned 75% New Guinea Gold and 25% Vangold Resources Ltd.

All samples are sawed, half core samples which are logged and photographed on site before sampling. Assaying was completed at accredited laboratory ALS-Chemex in Townsville, Australia.

18m at 22.60 g/t Gold: 12m at 25.66 g/t Gold and 19m at 19.02 g/t Gold in Grade Control Drilling at Sinivit Project

Gold Production to begin in April

5th April 2007 - Vancouver, BC. New Guinea Gold Corporation ("NGG") continues to define high grade, near surface gold, at the Sinivit Project, Papua New Guinea. NGG has an effective 92% interest in the Project.

Gold assays have been received for the initial program of grade control drilling completed within and across the Southern Oxide Pit area at Sinivit. Assays have been received from fifty-nine reverse circulation drill holes, each approximately 30m in length, that were completed along drill section lines spaced approximately six metres apart.

The drilling program covers a strike length of approximately 100 metres extending from 9780N through to 9876N. The better results are summarised below:

Note: The intervals above use a 0.5g/t gold cutoff, no high grade top cut has been applied

Complete assay results and hole location data for all 59 holes are attached as an appendix.

Bob McNeil CEO of NGG stated: "These results are quite exciting and much higher than results from earlier resource definition drilling. They correspond to the sub-surface extensions of trench results, such as 13m at 13.5g/t gold, released on 15th February 2007. The new drill results represent the best drill results encountered at Sinivit and all are near surface. These drill results correspond with original resource drilling results illustrated on Resource Outline Sections 9822N, 9845N, and 9864N (see sections under Sinivit Project, www.newguineagold.ca). There appears to be several times the amount of gold present in the new drill holes than in the original resource drill holes. For example the original intersections used on the resource estimate on Section 9845N were: 4m at 9.41g/t gold, 2m at 1.03g/t gold, 4m at 1.8g/t gold and 5m at 2.65g/t gold. The new intersections on Section line 9840N included 12m at 25.66g/t gold and 10m at 9.88g/t gold. All intersections on these lines are shown in the appendix. On section 9864N the best result in the original drilling was 14m at 9.75g/t gold whereas in this phase of drilling 19m at 19.02g/t gold was intersected.

Of the two trenches completed at the central and northern zones, the central zone width of 30m at 2.54g/t gold is particularly encouraging.

The high grade oxide gold mineralisation confirmed by the drilling will be accessed during the start up of open pit mining at the southern oxide zone, allowing early treatment of high grade gold mineralisation".

All the assay data has been loaded into the geological database and ore block interpretation using Surpac Vision mining software is in progress.

Reverse circulation drilling continues to progress satisfactorily in the northern area of the Southern Oxide Pit. Approximately forty holes with an average hole depth of thirty metres remain to be completed.

All samples are partly prepared with initial crushing and splitting down to 500 grams at site with further preparation and analysis at accredited ALS Chemex laboratories in Townsville, Queensland, Australia.

Initial gold production at Sinivit is expected to begin later this month.
Investors are cautioned that the development of Sinivit is proceeding in the absence of a full feasibility study. These evaluations are preliminary in nature and are based entirely on indicated mineral resources, which have not been categorized as mineral reserves. There is no assurance that the operating and financial projections in the preliminary assessment will be realized. Mineral resources that are not reserves do not have demonstrated economic viability. Measured and indicated mineral resources are that part of a mineral resource of which quantity and grade can be estimated with a level of confidence sufficient to allow the application of technical and economic parameters to support mine planning and evaluation of the economic viability of the deposit. An inferred mineral resource for which quantity and grade can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verified.
