TOMBILL MINES EMBARKS ON ITS SURFACE EXPLORATION PROGRAM AND COMPLETES INAUGURAL NEAR SURFACE DRILLING
Tombill Mines Ltd. has provided an exploration update at its 100-per-cent-controlled, royalty-free, flagship and patented Tombill main group and its claims within the Geraldton gold camp.
Summary of recent results from the Talmora near-surface drill program:
Hole TAL21-002 returned 1.65 grams per tonne gold over 11.5 metres around the past-producing Talmora gold mine.
Summary of previously released results from phase 1 drill programs to date:
Hole TB21-005E, a wedge hole drilled from mother hole TB21-005, returned 5.29 gpt gold over eight m from the targeted F zone. A second interval of 13.88 gpt gold over two m was encountered somewhat deeper in a new mineralized structure (deemed the F2 zone).Hole TB21-005B, another wedge hole drilled from hole TB21-005, returned 8.15 gpt gold over 4.1 m from the F zone.Hole TB21-005A, the first wedge hole drilled from TB21-005, returned 6.23 gpt gold over 13.3 m, confirming Hardrock's robust F zone extends onto Tombill's flagship property. The company is encouraged by the number of other multiple subsidiary zones that the drilling has intersected both above and below the main F zone target. These subsidiary zones are relatively narrow where they have been intersected due to their different plunge orientation when compared with the F zone. It is anticipated that these zones will be the focus of additional work after the F zone has been more fully delineated.
Results from the Talmora near-surface drilling program
Tombill has completed an initial drilling program to investigate the extent of near-surface gold mineralization around the historical Talmora mine on Tombill's main group claims. Tombill is investigating this area to understand the potential for broad lower-grade halos of gold mineralization around the narrow higher-grade veins historically mined in this area.
The Talmora drill program consisted of three diamond drill holes totalling 1,146 metres of core drilling and was targeted to test the area around the Talmora vein (also referred to as the Elmos vein in some historical records). The historical Talmora vein was explored, and test mined, from a shaft driven on an island in Kenogamisis Lake during several phases of work during the 1930s and 1940s.
The three holes in this program each intersected the Talmora vein within strongly foliated and sericite-altered gabbro/diorite host rocks with up to 3 per cent pyrite and 1.5 per cent arsenopyrite mineralization. Gold values associated with these intercepts are shown in an attached table. The best result from the program was in hole TAL21-002, which returned 1.65 gpt Au over 11.5 metres at a depth of 154.5 to 166 metres down the hole.
The gabbro/diorite intrusive rocks hosting the gold mineralization encountered in these initial three drill holes are relatively competent and impermeable, and usually not the ideal host for the broad halos of low-grade mineralization in the Geraldton area, so the company is pleased to see some positive indicative results.The Talmora vein, several hundred metres along strike to the east, is hosted in greywacke, which is a more-favourable host rock and hosts much of the near-surface lower-grade mineralization on the adjoining property of Greenstone Gold Mines. Tombill is considering a drill program to test the Talmora/Elmos vein further along strike to the east, where it is hosted in the more-favourable greywacke host rocks. The program will require drilling under a lake.
Tombill will maintain its exploration program drill testing to define the extent of the F zone, where recent drilling has confirmed the westward extension from the adjoining Greenstone Gold Mines property onto the Tombill main group claims. In addition, Tombill is also reviewing other geological and geophysical targets on its Geraldton gold camp claims, including the area around the past-producing Tombill and Talmora mines, to evaluate the potential for near-surface mineralization. To date, seven areas have been stripped and mapped, and, where appropriate, channel sampled. To date, the surface stripping and sampling program has returned anomalous results of up to 3.2 gpt over two m.
