Lode Resources Ltd Announces High-Grade Copper and Zinc Intersected At Trough Gully Mine
Lode Resources Ltd. reported Phase I drilling has returned significant copper & zinc assays plus consistent gold and silver credits at Trough Gully Copper Mine, part of the Lode's 100% owned Fender Copper Project. Phase I drilling resulted in six drill holes for 574 metres. TGY003, TGY007 & TGY006 have returned significant assays as summarised below and with interval assays shown in Tables 1, 2 & 3. TGY001 intersected anomalous mineralisation and TGY004 & TGY005 are awaiting assays. TGY002 hole was abandoned early due to a collapsed collar. TGY007: 7.30m @ 1.37% copper, 4.93% zinc, 0.36g/t gold, 10.1g/t silver from 92.1m (TW 3.80m), Inc: 1.90m @ 1.99% copper, 3.91% zinc, 0.34g/t gold, 12.1g/t silver from 92.1m, TGY003: 6.90m @ 1.30% copper, 4.49% zinc, 0.50g/t gold, 17.4g/t silver from 50.9m (TW 4.10m), Inc: 1.00m @ 3.05% copper, 12.25% zinc, 1.15g/t gold, 43.2g/t silver from 51.5m, TGY006: 2.80m @ 0.5% copper, 0.83% zinc, 0.16g/t gold, 3.3g/t silver from 67.6m (TW 1.40m), The TGY003 intercept above is situated within a roader zone returning 10.00m @ 0.92% copper, 3.22% zinc, 0.36g/t gold, 12.1g/t silver from 49.00m (TW 5.90m). Drill hole TGY007, which intercepted of high-grade copper and zinc mineralisation is located 30m below the deepest working demonstrating open-endedness at depth. Prior to this campaign by Lode the Trough Gully Copper Mine had never been rilled despite a history of copper production that occurred periodically in the late 1800's and early 1900's. Mineralisation mined was primarily copper carbonates hosted by sheared udstone, phyllite, siltstone and jasper, although banded and massive sulphidic ore was also found close to the surface. High-grade copper ore was dispatched from the mine from 1899 to 1916 and a reverberatory furnace was erected on the site in 1908. A representative section of mineralisation from drill core has been submitted for metallurgical tests. Early evidence that metals of value can be recovered through an economically viable industry standard processing route is as important initial step in assessing a mineral occurrence. It also allows metal equivalent values to be calculated under the JORC code. Metal equivalent values are an easy way to demonstrate overall metal grade of intercepts via a single figure. Lode is planning to carry out a down hole electromagnetic (DHEM) survey, utilizing drill hole TGY007, to test for extensions at depth and along strike. At this preliminary stage it is postulated that Trough Gully Mine mineralisation is present in foliation boudinage lenses. This may be the result of VMS style mineralisation being remobilised post burial due to heat and pressure (also known as metamorphic flow) and redeposit into lenses of varying thickness. DHEM may help locate possible thicker lenses prior to the commencement of Phase II rilling. In addition to the Trough Gully Mine, the Fender Copper Project encompasses numerous copper occurrences and copper drainage anomalism over large areas including two large copper drainage anomalies called Kasey (7km x 3km) and Fold (4km x 2km) as outlined below. The Fender Copper project is located 30km southeast of Tamworth. The geology is dominated by Late Devonian-Early Carboniferous Myra and Sandon Beds as well as inter-fingered Permian basalt, jasper and chert. Surface exploration carried out by several companies since the 1960s comprising stream/soil, surface mapping, IP and magnetics, however no drilling has occurred except for one very small and poorly design programme at the Fisher's Mine prospect. Significant copper values were returned from stream sampling over two large areas (Kasey 7km x 3km, Fold 4km x 2km). This coincides with distinct large agnetic ridges and adjacent to Spring Creek fault. It can be postulated that magnetic anomalies may represent large fold structures which provides tension regime for fissure infilling of remobilised copper mineralisation. Some 21 copper occurrences of Volcanic Massive Sulphide (VMS) origin have been recorded over 30km strike length and are usually associated ithin steeply dipping shear zones that have a close spatial relationship with jasper, chloritised metabasalt and less resistant argillaceous chert. The mineralisation is typically Fe rich, followed by Cu and lesser Zn as major metals. Copper grades in small historical workings typically ranges from 2% to 4.5%, although exceptionally rich ore from the Fishers mine averaged more than 13.4% Cu. Identified drill targets include four historical copper mines (Trough Gully, Mulla Creek, Fishers and Mt Pleasant Copper Mines) and, with further surface work, two large drainage anomaly targets based on regional stream/soil geochemical and magnetic surveys. These large anomalies could suggest potential for a sizeable occurrence.
