TOMBILL MINES PROVIDES EXPLORATION UPDATE ON ITS FLAGSHIP PROJECT
Tombill Mines Ltd. has provided an exploration update at its 100-per-cent-controlled, royalty-free flagship and patented Tombill Main Group property within the heart of the Geraldton gold camp.
1) Surface exploration program:
- Surface stripping and sampling program is under way.
- Multiple new targets were identified from recently collected airborne magnetics data.
- Grab samples from the East Porphyry zone returned 24.3 and 14.9 grams per tonne (g/t).
2) Deep drilling program:
- Phase 1 drilling at the Tombill Main Group is continuing with a total of more than 6.6 kilometres (km) completed on five parent holes and two daughter wedge holes.
- Assay results should be released over the next few months.
Adam Horne, chief executive officer, commented: "Our technical team are doing a fine job in executing our drilling and surface program. In line with our neighbour, we are hoping to present a diversified gold system including extensions of known lodes at depth but also new discoveries at our multiple near-surface targets. We have an aggressive exploration program this year, the first modern exploration program on this highly prospective property. We look forward to good news on several fronts over the course of the next few months."
Surface exploration program update
Detailed magnetic data from Tombill's unmanned aerial vehicle-magnetometer survey (UAV-MAG survey) have been utilized to create new near-surface targets, based on refolded lithologies and east-west structures oblique to regional foliation.
The magnetics map has been analyzed together with geology mapping and historic showings resulting in definition of multiple new targets. Tombill has now identified a total of 10 surface targets, including the past-producing Talmora mine. Near-surface targets are being accessed with bulldozer trails in preparation for stripping of overburden to facilitate detailed mapping and channel sampling. Tombill is continually updating a Bayesian ranking system as more data are acquired in order to refine and rank targets for exploration. The goal of surface exploration is to identify near-surface targets, those defined as extending down to 300 metres (m) depth, that will be tested by drilling in Q2/Q3 2021.
Assay results from grab samples of historic trenches
Trails have been completed to the various targets and historic showings are being evaluated. The highest-ranked surface target is the East Porphyry zone which saw limited sampling and drilling in the 1930s. The first pit encountered was subjected to grab samples of mineralization.
Grab samples were taken in the first trench from the East Porphyry zone and submitted for assay, results in the attached table show the sample number, followed by the co-ordinate location and a brief description of the rock.
Amongst multiple samples, the Greywacke and mineralized banded iron formation (BIF) in the first trench sampled within the East Porphyry zone returned samples of 24.3 and 14.9 g/t gold, respectively. Samples 447972 and 447959 contain coarse-grained disseminated pyrite with silica that replaced the magnetite bands. This is similar mineralization as the North zone ore that was mined from the historic underground mines on the adjacent Hardrock project.
The company cautions that grab samples have no widths associated with them and are not necessarily indicative of the mineralization on the Tombill Main Group. They are used to assist in pinpointing the first areas to be assessed by stripping and channel sampling.
Mineralization is adjacent to a quartz-feldspar porphyry (QFP) dike that is sericite altered. The QFP is the same dike that extends from the proposed open pit at the Hardrock mine and is also the same QFP associated with F-zone-type mineralization at depth as outlined by Tombill's deep exploration program.
Deep drilling program update
Phase 1 drilling at the Tombill Main Group is continuing with five main holes completed and two planned wedges:
- Daughter hole TB21-001A was completed to a downhole depth of 1,220 m and intersected the target zone. The company sent 397 samples for assay.
- TB21-002 was completed to a downhole depth of 1,453 m. It sent 505 samples for assay.
- TB21-003 was drilled to 891 m downhole, but was abandoned due to encountering a large water-filled cavity. It sent 339 samples for assay.
- TB21-004 was completed at a downhole depth of 1,394 m and intersected the target zone. It submitted 626 samples for assay.
- TB21-005 was drilled to a downhole depth of 875 m. It submitted 310 samples for assay.
Drill hole TB21-005 was wedged at 600 m to drill daughter hole TB21-005A. This is continuing and on track to intersect the central part of the target zone. The hole is currently at 975 m downhole depth.
As of May 8, 2021, Tombill's phase 1 drilling program has been executed by Rodren Drilling.
A second Rodren drill arrived earlier this week and is accelerating the program. Drill hole TB21-004 will be wedged and daughter hole TB21-004A will be drilled.
To date, more than 6.6 kilometres (km) of core have been drilled. When assays are received from the present drill holes, a synopsis of the deep drill results should be released over the next few months.
