Step-Out Drilling On The Lightning Zone At Rabbit North Identifies New Gold Grain Dispersal Train

VANCOUVER - Tower Resources Ltd. reported on recent step-out diamond drilling program on the Lightning Zone at Rabbit North property near Kamloops, British Columbia. While performing the drilling, Tower collected two till samples that revealed a new, much coarser grained and thus higher grade gold dispersal train 400m west of the Dominic Lake Train that emanates from the Lightning Zone and led to its discovery.

The new dispersal train has been named the Central Train because it lies midway between the Dominic Lake and Durand Creek Trains. The two new till samples from the train, Nos. 245 and 246, yielded 318 and 301 gold grains, respectively, including many coarse, sand-sized grains that contribute much more Au than the usual silt-sized grains. They were collected up-ice (northwest) at 30 m step-outs from a 169-grain gold anomaly that was obtained from Sample 068 in in Tower's inaugural , 137-sample reconnaissance till survey in May, 2021.

Tower's till sampling and sample processing contractor, Overburden Drilling Management Limited (ODM), has studied many gold grain dispersal trains over nearly 50 years. For trains as significant as those at Rabbit North, ODM has determined that the Au grade of the heavy mineral fraction of the till where the gold grains reside, calculated from the number of grains recovered from a sample and the measured dimensions of these grains, is predictive of the grade of the bedrock source from which the grains are derived, provided that the grade is normalized to the average 0.4% (1 particle in 250) heavy mineral content of till in Canada.

The grades of the Dominic Lake Train and its source, the Lightning Zone, uphold the above relationship, indicating that it should also apply to the new, richer Central Train. The average normalized Au grade of the heavy mineral fraction of the 22 follow-up till samples collected from the Dominic Lake Train in October, 2021 was 1.54 g/t, closely matching the grades of the first three drill intersections of the Lightning Zone (1.40 g/t over 95 m in Hole 026, 1.55 g/t over 138 m in Hole 028 and 1.78 g/t over 70.5 m in Hole 029. The Au grades for the heavy mineral fraction of the till in Samples 245 and 246 on the Central Train are much higher at 3.90 and 21.67 g/t, implying a correspondingly higher source grade. The coarseness of the gold grains is responsible for the higher Au grades and suggests that the gold mineralization may have a significant vein component.

Joe Dhami, President, said, "Our new, gold-rich Central Train and previously announced Durand Creek Train clearly show that we have found a large gold system at Rabbit North and the Lightning Zone is not a one-off discovery. We are very excited about both the grade potential of the indicated new gold zone and its great location just 400 m from our Lightning Zone."

Samples 245 and 246 were collected about 150 m down-ice from a band of Miocene basalt flows that cover the older, gold prospective, fragmental volcanic rocks. Most of the gold grains recovered from these samples are perfectly pristine, effectively limiting their source to the 150 m wide corridor between the sample sites and basalt flows. Depending on its orientation, the gold source may be partly covered by the basalt flows and thus not fully represented in the dispersal train.

The sample sites are also just 150 m glacially up-ice from a 750 m long Au anomaly identified in a historical soil survey. This anomaly is oriented sub-parallel to the southeast ice flow direction, suggesting that it may be part of the Central Train. If so, a 116 grain gold anomaly identified 200 m down-ice from the soil anomaly in the May, 2021, till survey may also form part of the train. However, the soil anomaly is also sub-parallel to the Lightning Zone and thus, alternatively, could indicate the strike of the mineralized zone from which the gold grains and soil Au anomaly are sourced.

The recent step-out diamond drilling program on the Lightning Zone ended with a fifth hole, No. 038, being drilled to undercut the long gold intercept of Discovery Hole 026 (95 m of 1.40 g/t Au including 19.2 m of 4.42 g/t Au). Two additional step-out holes that had been planned further along strike from the northernmost hole, No. 037, were deferred due to a delay in obtaining drilling permits for these sites. The five completed holes totaled 975 m.

Hole 038 was collared 50 m behind Discovery Hole 026 and drilled beneath it at a similar azimuth and at the same -60° dip to a depth of 291 meters. It encountered 83.2 m of pervasive sericite-silica-pyrite alteration between 52.2 and 136.0 m down-hole. Pyrite veinlets similar to those in the higher grade portion of Hole 026 (4.20 g/t Au over 19.2 m) are common but tend to be crushed, indicating stronger deformation that may positively influence Au grade since the mineralization is shear controlled. All core has been submitted for analysis.
