(TSXV: TWR) (\"Tower\" or the \"Company\") is pleased to report that it has begun the planned follow-up till sampling program on the Company's Rabbit North porphyry copper-gold property near Kamloops, British Columbia (Fig. 1).The objective of the till survey is to develop specific diamond drill targets from the strong gold grain anomalies that were identified in the heavy mineral fraction of the till in an inaugural survey in May, 2021 (see Tower's August 28, 2021 press release). These gold grains were glacially liberated about 10,000 years ago from mineralized zones of the porphyry Cu-Au type and were then dispersed \"down-ice\" (along the direction of ice flow) to the southeast. The anomalous till would originally have contained many more Cu-sulphide grains than gold grains but only the gold grains survived post-glacial weathering of the till and can be used to locate the mineralized zones.The prime target of the present survey is the very strong, 600 grains-per-sample gold anomaly in Samples 58 and 59 (Fig. 1). These contiguous samples were collected 200 m apart on a low-lying till plain overlying volcanic rocks south of the alkalic Durand Stock which, at higher elevations, contains several outcropping Cu-Au showings.Gold is malleable and most of the grains in Samples 58 and 59 were significantly but not completely deformed by the ice (Fig. 2) during transport to their present location, suggesting that they are derived from a single bedrock source and that this source is less than 1 km up-ice. The gold grains also have a relatively high fineness (purity) between 880 and 980 (88 to 98% Au, 2 to 12% Ag), a consistency that further supports derivation of the grains from a single mineralized zone.The most probable location of the inferred gold source is about 600 m up-ice (to the northwest; Fig. 1), near the head of the till plain on which the gold grain anomaly is located. This till-covered area lies between the minor Dominic and Buff Cu-Au showings to the east and west, respectively, and is 300 m south of and 30 m lower in elevation than the outcropping Chrysocolla Zone. Fourteen samples will be collected at a spacing of 100 x 200 m to locate the head, or orig...
