Thunder Gold Corp. announce results from the first three holes of the 2023 phase one drill campaign currently underway at the Tower Mountain Gold Property, located 50-km west of Thunder Bay, ON, in the Shebandowan Greenstone Belt.
- TM23-137 intersected 941.0 g/t Au over 1.50 metres with multiple sites of visible gold observed at a depth of 126.7 metres downhole within a broader interval averaging 1.81 g/t (CAPPED at 30.0 g.t Au) over 41.0 metres;
- TM23-137 also intersected 0.77 g/t Au over 23.0 metres and 0.83 g/t Au over 58.0 metres;
- TM23-138 intersected 1.26 g/t Au over 17.5 metres and 0.71 g/t over 119.0 metres;
- TM23-136 intersected 0.68 g/t Au over 12.0 metres and 0.75 g/t Au over 11.7 metres;
- The three holes establish 200 metres of mineralized strike length along a previously untested N-S corridor;
- All three holes terminate in mineralization;
- This new zone, identified by geophysics, offers over 1000 metres of untested strike length and remains open in all directions.
Wes Hanson P.Geo., CEO of Thunder Gold, notes: “Any time you come out of the gate with visible gold and the highest grade ever reported from a property with over 25,000 historical core samples, you’ve got to be excited. The rather impressive 941.0 g/t Au reports over a 1.5 metre interval and is driven by multiple sites of visible gold occurring within a centimetre scale quartz-carbonate-tourmaline vein intersected at a depth of 126.7 metres downhole. The vein occurs within a 41.0 metre interval averaging 1.81 g/t Au (interval capped at 30.0 g/t Au). The cap ONLY affects the 941.0 g/t interval containing the observed visible gold, all remaining assays within the 41.0 metre interval range from 0.09 to 5.80 g/t Au.
“The results from the first three holes clearly demonstrate the validity of our exploration model and the validity of Induced Polarization (“IP”) as an efficient, accurate, exploration vector. All three holes intersected widespread, low-tenor (+0.10 g/t Au) gold mineralization from surface to the end of each hole as anticipated. Holes TM23-137 and 138 intersected elevated gold grades (+0.30 g/t) over intervals ranging from twelve (12) metres to one hundred and nineteen (119) metres, returning weight averaged grades ranging from 0.68 to 1.81 g/t Au. The frequency of intervals greater than 0.30 g/t Au is double that of the historical data population, as predicted.
“In simple terms, these holes, targeting an untested IP anomaly along a 1000-metre strike length, are returning high gold grades, more frequently than the historical data set. It is important to note that the average reported grades are consistent with the average operating and reserve grades reported at all large-tonnage, low-grade open pit mines and development projects in Canada today.
“The Company is also pleased to report that inversion of the recently completed IP survey is nearly complete. Preliminary analysis has identified new targets to the east and south of the Tower Mountain Intrusive Complex with a similar response to the known areas of mineralization. The preliminary interpretation has also isolated strong north-south lineaments, the longest and strongest of which is the focus of the phase one drill campaign currently 50% completed. This lineament extends for over 1000 metres of untested strike length. With only 20% of this untested area assayed, we are are already seeing strong evidence supporting our conceptual exploration model and we continue to demonstrate the validity of a cheap, cost-effective primary exploration vector. We are also beginning to piece together a working geological model which will guide future exploration. We see a unique opportunity at Tower Mountain: a path towards a large-tonnage, low-grade gold discovery located in a premium mining jurisdiction, fifty (50) kilometres from a major population centre, with year-round paved highway access, significant exploration upside, viable predictive tools and low exploration costs. Our goal is to rapidly demonstrate the potential for a large-tonnage, low-grade gold discovery.”

Interval length is reported down hole which is equivalent to true width.
A grade cap of 30.0 g/t was applied to estimate the capped average grades. This capping factor affect one sample in holeTM23-137 from 125.5 to 127.0 metres.
Figure 1.0 presents the current drill plan of the Tower Mountain Property. Holes TM23-136, 137 and 138 are highlighted for reference. The three holes define 200 metres of new mineralized strike length moving from south to north, from the Bench target.
The underlay is a filtered version of the current working IP chargeability inversion. This data is still being interpreted and is subject to change but all changes are anticipated to be minor. The strong, linear, north-south trending finger is the primary exploration target being evaluated in the phase one drill program. This chargeable response measures 1000 metres along strike and is more than 200 metres wide.
Gold mineralization continues to be agnostic relative to rock type with gold occurring in both the alkali intrusives as well as the host volcanics. Alkalic syenites and monzonites are more prevalent approaching the main Tower Mountain Intrusive Complex. These intrusives postdate the volcanics and appear to have generated extensive micro-fracturing of the host volcanic rocks that were later flooded with fine pyrite and possible gold. Late quartz-carbonate veins with coarse visible gold are interpreted to represent the final stage of mineralization.

A large piece of visible gold has been highlighted in the white circle – with arrows pointing to numerous other visible gold sections.
Quality Assurance and Quality Control
Diamond drilling utilizes NQ diameter tooling. The core is received at the on-site logging facility where it is, photographed, logged for geotechnical and geological data and subjected to other physical tests including oriented core measurements and magnetic susceptibility analysis. Samples are identified, recorded, split by wet diamond saw or hydraulic splitter, and half the core is sent for assay with the remaining half stored on site. A standard sample length of 1.5 meters is employed, varying only at major lithological contacts. Certified standards and blanks are randomly inserted into the sample stream and constitute approximately 5-10% of the sample stream. Standard and blank performance is monitored with any failures evaluated and investigated to determine if said failure is a result of error during submission. Any unexplained failures are identified and the five samples preceding and following the failure are re-assayed. Standards and blanks are inserted into the re-assayed interval stream as well to monitor analytical performance. Samples are shipped to the Activation Laboratories Ltd. facility in Thunder Bay, ON where sample preparation and analyses are completed. All samples are analyzed for gold using a 30-gram lead collection fire assay fusion with an atomic adsorption finish. All results greater than 5.0 g/t Au are re-assayed using a gravimetric analysis. All samples are also analyzed for 35-element induced coupled plasma analysis.
About the Tower Mountain Gold Property
The Tower Mountain Gold Property is located 5-km off the Trans-Canada highway, 50-km west of Thunder Bay, Ontario. The property lies within the late Archean Shebandowan greenstone belt, an emerging gold district in northwestern Ontario. The property consists of unpatented and patented lands totalling 1,968 ha. Exploration to-date suggests the property offers a large gold endowment. Gold mineralization is widespread, and diamond drilling has identified low-grade gold mineralization extending outward for at least 500-meters from a central alkalic intrusion known as the Tower Mountain Intrusive Complex. Drilling has established persistent gold grades from 0.1 to 1.0 g/t along a 1,500-meter-long x 500-meter wide x 500-meter deep block of volcanic-volcanoclastic rocks immediately west and adjacent to the central alkalic intrusion. The remaining 6,000 meters of strike length surrounding the intrusion are untested. Tower Mountain shows many of the classic indicators of being an Intrusion Related Gold Deposit, which is a highly desirable exploration target.
