WELCOME TO IMPACT MINERALS LIMITED
Impact Minerals Limited is an exploration company listed on the ASX in November 2006.
The Company manages extensive tenement holdings (>2,000 km2) within Australia featuring significant potential for high-grade mineral deposits of gold, silver, lead, zinc, copper, nickel and PGM’s.
The Directors of the Company have extensive experience in mineral exploration and a strong history of exploration success, business development and corporate management.
Impact Minerals intends to build wealth for its shareholders through a vigorous campaign of project generation and evaluation with a view towards profitable mining operations.
Four exploration projects with numerous, high-grade targets progressed to active drill testing.
All projects located within Australia (NSW, QLD, WA), one of the world’s most stable jurisdictions.
Gold, silver and base metal resources identified near existing mining infrastructure in NSW.
Strong cash position with solid backing to advance prospects to resource definition.
The Commonwealth Project comprises 902 km2 of exploration licences located 50 to 100 km north of Orange, NSW in the prolific gold and copper rich Lachlan Fold Belt.
Impact is targeting two types of deposits:
- Porphyry Copper-Gold deposits such as Cadia-Ridgeway (40 million ounces gold and 10 million tonnes copper) and the recently discovered Boda prospect (Alkane Resources Ltd) just a few kilometres from Impact’s project area; and
- Volcanic Massive Sulphide deposits such as Woodlawn (7 million ounces gold equivalent).
Impact has defined Inferred Resources at the Commonwealth Project that contain 88,800 ounces of gold, and 3,300,000 ounces of silver with significant zinc and lead credits, all within 250 metres of surface and with potential for bulk open pit mining. The resources come from two deposits, Commonwealth and Silica Hill that are about 150 metres apart.
The Inferred Resource at Commonwealth (Main Shaft to Commonwealth South) is 912,000 tonnes at 2.4 g/t gold, 44 g/t silver, 1.2% zinc and 0.5% lead including 142,000 tonnes at 4.5 g/t gold, 161 g/t silver, 4.6% zinc and 1.7% lead in the high grade massive sulphide lens at Main Shaft.
At Silica Hill the maiden Inferred Resource at a 50 g/t silver cut-off is 710,000 tonnes at 0.8 g/t gold and 88 g/t silver.
Both deposits are open at depth and along trend beyond exceptional drill results such as:
Main Shaft: 5.7 metres at 3.8 g/t gold, 347 g/t silver, 10.8% zinc and 3.7% lead including
0.5 metres at 4.9 g/t gold, 917 g/t silver, 10.2% zinc and 4.6% lead.
Commonwealth South: 8 metres at 5.1 g/t gold, 20 g/t silver, 1.3% zinc and 0.5% lead including 0.5 metres at 34.3 g/t gold, 40 g/t silver, 5.8% zinc and 2.3% lead; and
4 metres at 41.8 g/t gold (1.3 ounces per tonne), 93 g/t silver, 5.5% zinc and 2.3% lead.
Silica Hill: 22.5 metres at 1.7 g/t gold and 276 g/t silver;
including 0.3 metres at 1.8 g/t gold and 4,200 g/t (135 ounces or 0.42%) silver;
and also including 0.8 metres at 13.6 g/t gold and 40 g/t silver.
The Commonwealth-Silica Hill deposits have unique similarities to the world class Eskay Creek gold-silver rich volcanogenic massive sulphide (VMS) deposit in Canada.
Exploration is focused on immediate extensions to these existing resources.
In addition, exciting new targets for porphyry copper gold mineralisation have been defined at Apsley and other areas close to the Boda discovery. At Apsley alteration and pathfinder metal assemblages are suggestive of a large undrilled porphyry-related copper-gold system with copper minerals at surface over a 2 sq km area. Follow up exploration to define drill targets at these prospects is underway.
The Broken Hill Project comprises seven exploration licences covering 816 square kilometres near Broken Hill, NSW. The project is prospective for both nickel-copper-PGE mineralisation associated with ultramafic-mafic rocks and zinc-lead-silver in “Broken Hill-style” deposits hosted mostly by metasedimentary rocks and amphibolite.
Impact has discovered exceptional grades of platinum group elements, nickel and copper, several significant high grade drill results from two prospects and high grade silver-lead-zinc at a third:
- At Red Hill Impact drill hole RHD012 returned a bonanza drill intersect of 3.5 metres at 5 g/t platinum, 6 g/t gold, 144 g/t palladium, 2.9% nickel, 2.3% copper and 14.5 g/t silver in sulphides associated with veins and structures. These are some of the highest platinum and palladium grades in Australia.
- At Platinum Springs high grade magmatic nickel-copper-PGE sulphides were intersected in drill hole PSD02 which returned 2.75 metres at 3.5 g/t platinum, 7 g/t palladium, 0.4 g/t gold, 2% copper, 1.9% nickel and 11.6 g/t silver from 55 metres down hole.
- At Dora East Impact has discovered high grade massive and disseminated zinc-lead-silver mineralisation with RHD018 intersecting 5.1 metres at 10% zinc, 0.8% lead, 40.4 g/t silver from 148.4 metres downhole.
Impact’s exploration results indicate the potential for platinum mineralisation stretching over a 40 km belt of mafic-ultramafic rocks within the richly-endowed Curnamona Craton. The mafic intrusions are dated circa 820 Ma and appear coeval with a major global nickel-mineralising event which includes the world-class Jinchuan nickel-copper deposit in China.
Impact’s extensive land holdings around Broken Hill make the company one of the largest tenement holders in this very prospective terrain. Despite 150 years of exploration since the discovery of the giant Broken Hill Mine (>300 Mt of ore) the region is still very poorly explored for zinc-lead-silver deposits and many targets remain to be tested.
- Two kilometre long target for high grade gold-silver-base metal mineralisation identified.
- First diamond drill hole at the project delivers stand out drill intercept of 0.7 metres at 10.9 g/t gold, 146 g/t silver, 8.3% zinc and 5.1% lead in epithermal vein.
- Drill hole lies at southern edge of the two kilometre long target identified from zoned metal assemblages in drill assay data.
- Metal assemblage and vein textures are characteristic of epithermal veins related to magmatic fluids sourced from a porphyry intrusion of intermediate composition.
- Target zone lies between a core/proximal zone of Cu-Mo-Bi-Te-W close to the parent intrusion and a distal epithermal zone of As-Ag-Sb+/-Au.
- Major programme of close spaced drilling to identify high grade shoots required.
- Project available for joint venture.
Impact holds one Exploration Licence in Queensland (EPM 14116) located about 20 km southeast of Clermont. One third of the area is interpreted to be underlain by prospective “Cycle 1 Volcanics” beneath an extensive cover of younger rocks and regolith. Black soil cover has hindered previous exploration and there are many encouraging drill intercepts and undrilled prospects that are still to be followed up.
In May 2020 Impact made applications for five tenements that will comprise 100% ownership of a major new project prospective for nickel-copper-platinum group metals and gold in the emerging new province for these metals in the south west Yilgarn Craton in Western Australia once granted. Key features of the project are:
- Located in SW Yilgarn Terrane 130 km east of Perth.
- Mafic and ultramafic rocks in major mobile belt.
- Deformed extension of terranes to the NE of Perth including Julimar-Yarawindah-Moora areas.
- Significant gravity anomalies and “eye structures” in magnetic data.
- Nickel-copper-gold anomalies in regional geochemistry data sets.
- No previous exploration.
