Second drill has been added to accelerate Phase One drilling
Deep drilling program has produced 2,700 m of drill core to date
Drill core is presently being logged and sampled
Detailed airborne drone-based magnetics survey just completed
Begun surface work at historic near-surface target
Vancouver, British Columbia--(Newsfile Corp. - April 1, 2021) - Tombill Mines Limited (TSXV: TBLL) (the "Company" or "Tombill"), is pleased to announce that it has begun an extensive integrated exploration program at its 100% controlled, royalty-free flagship and patented Tombill Main Group property within the Geraldton Gold Camp.
Exploration and Drilling Plan Highlights
- The first Phase One diamond drill hole, TB-21-001, has been completed to a down hole depth of 1,219 m. Drill core is presently being logged and sampled. A wedge "daughter hole," TB-21-001A, was started at a downhole depth of 500 m and is responding well with directional wedging. Such wedge drilling has been utilized successfully at the Hardrock deposit immediately east of Tombill Main Group.
- A second drill has been added to the deep-drilling campaign as per plans to accelerate the Phase One drilling. Drilling has begun on hole TB-21-002 which is currently at a down hole depth of 750 m and is on track to intersect target. (See Figure 1, where the background shows the well-known local landmark, the MacLeod #2 Headframe that is in the middle of Hardrock's proposed open pit)
- An Unmanned Aerial Vehicle-Magnetometer Survey ("UAV-MAG Survey") has been completed on the Tombill Main Group. Tombill's geological personnel have identified cross-cutting features associated with refolded lithologies and structures. These new targets are being added to the near-surface exploration campaign: (See Figure 2)
- Eight surface targets were defined, including the past producing Talmora Mine,
- This campaign is the first conducted at historic near-surface targets utilizing modern exploration techniques.
- Areas of near-surface targets are being accessed with bulldozer trails in preparation for stripping of overburden, allowing detailed mapping and channel sampling:
- Tombill is continually utilizing a Bayesian ranking system to target as more data is acquired,
- The goal of the current surface campaign is to identify near-surface targets down to 300 m depth to be tested by future drilling.

Deep Drilling Program
- The Phase One drill plan is comprised of a 15 drill hole (5 hub-holes + 10 daughter holes) campaign encompassing approximately 16,000 m.
The deep drilling program is focused on delineating extension and continuity from the neighbouring Hardrock Project's east to west resource plunge, especially the F Zone where their westernmost drill hole, MM170, encountered 18.49 g/t over 20.5 m. All mineralized zones at Hardrock continue onto Tombill Main Group's property.
- The Phase Two drill plan is comprised of a 63 drill hole campaign encompassing approximately 70,000 m. This program is contingent on the success of Phase One drilling.
Past producers and explorers at Tombill did not emphasize the search for open-pittable low grade gold resources. This strategy was successful at the adjacent Hardrock property, resulting in the delineation of 5.5 million ounces of Proven and Probable reserves, 2.6 million ounces of Measured and Indicated resources, and 3.4 million ounces Inferred resources1, associated with past-producing mines and the identification of 17 separate gold zones. Tombill geologists are presently:
- Conducting 3D modelling and interpretation of historical geologic data coupled with detailed drone magnetic data,
- Putting in bulldozer trails to open access to near-surface targets in preparation for stripping of overburden.
Upon opening surface exposures at these targets, the focus will be on:
- Conducting detailed mapping and sampling of stripped areas, and reconciling magnetics interpretation with observations of zone extensions and plunges,
- Continual ranking of targets using a Bayesian system for the selection of future drill targets.
