Tower Resources Ltd. announced completion of the till sampling and gold grain testing component of the Company's current 2000 m diamond drilling program on the Company's Rabbit North property near Kamloops, British Columbia, between New Gold's New Afton underground Cu-Au mine and Teck's Highland Valley open pit Cu-Mo mine. The gold grain results obtained from the till samples will be used to guide diamond drill testing of the large Dominic Lake gold grain dispersal train as soon as drilling is completed at the source of the smaller but higher-grade Central Train. As explained in Tower's December 21, 2022 the Lightning Zone that Tower discovered in December, 2021, 300 m glacially up-ice from the Dominic Lake Train, has been yielding attractive gold Au grades of up to 1.55 g/t over 132 m but its glaciated footprint appears to be too small to account for such a large gold grain dispersal train.

Additionally, Tower's diamond drilling has shown that the untested 300 m gap between the Lightning Zone and the previously sampled segment of the dispersal train is underlain by a plug of unprospective (pre-mineralization) Durand diorite rather than the gold-prospective Nicola tuff that hosts the Lightning Zone. In the current program, 11 till samples were collected in the gap. The samples were obtained beneath 1 m of snow using an excavator and were collected at the same depth as the original hand-dug samples that identified the Dominic Lake Train.

As anticipated, the gold grain content of most of the till samples from the gap, including those directly down-ice from the Lightning Zone, is significantly lower than that of the samples from the Dominic Lake Train (generally less than 150 grains per sample versus 200-600 grains per sample), confirming that the main gold source is probably on the south rather than north side of the diorite plug. Two till samples collected further north over the northeastern part of the diorite plug did contain more than 200 gold grains. However, this anomaly is probably related to an underlying zone of the earlier, low- grade, Durand-type porphyry Cu-Au mineralization that Tower intersected in Hole 035 in December 2021 (0.09% Cu and 0.31 g/t Au over 79.8 m. Three till samples were collected to verify an isolated 609-grain gold anomaly that was identified 200 m northeast of the Lightning Zone in the initial May 2021 till survey.

These samples yielded much lower gold grain values, indicating that the original anomaly was spurious rather than indicative of a systematic dispersal train like the initial till sample from the Central Train. Such anomalies are generally produced post-glacially by weathering of gold inclusions from auriferous sulphide grains in a mineralized till pebble. One till sample was collected over the band of young basalt flows at the head of the Central Train.

It yielded only 43 gold grains, confirming that the Central Train is sourced entirely from the Nicola volcanics on the south side of the basalt. Central Train Drilling Corroborates Interpretation of Dominic Lake Train While the till samples at the head of the Dominic Lake Train were being collected and evaluated, diamond drilling commenced at the head of the Central Train to locate its source. The anomalous till samples from this dispersal train contain only half as many gold grains as those from the Dominic Lake Train but three times more gold by weight because the gold grains are larger.

This suggests a source Au grade three times higher than the grade of the Lightning Zone. The drilling has been progressing rapidly, with approximately 1400 m completed in four holes. It has revealed that the Nicola volcanics at the Central Train are less disrupted by faults than those at the Lightning Zone, facilitating determination of the orientation of other structures.

Importantly, the mineralized shear zone responsible for the Central Train has been determined to strike roughly parallel to the south-southeast ice flow trend and to directly underlie the dispersal train, reinforcing the probability that the main source of the Dominic Lake Train also trends south-southeast and underlies the train. While more drilling is needed on the Central Train, the drill is now being moved to the Dominic Lake Train where at least two holes will be drilled to assess the gold potential of the rocks beneath the train.
