Tower Receives Rush Assays Averaging 2.0 g/t Au and 7.2 g/t Ag from Upper 7.3 metres of New 10.5-metre-wide Gold Zone in First Hole of 3000m Diamond Drilling Campaign at Nechako Gold Property

Vancouver, British Columbia--(Newsfile Corp. - April 28, 2021) - Tower Resources Ltd. (TSXV: TWR) ("Tower" or the "Company") is pleased to report that the first hole of the current 18-hole, ~3000-metre diamond drilling program on the Company's Nechako Gold property in south-central B.C. (Fig. 1), No. APR-18, intersected a completely new gold zone over a core length of 10.5 metres. Seven samples spanning the first 7.3 m of this zone were assayed on a "rush" basis and returned a weighted average of 2.0 g/t Au and 7.2 g/t Ag. Only limited rush assays are possible at the present time due to the very high level of exploration activity in Canada. Therefore assaying most of the core samples, including those from the lower part of the new gold zone, will require approximately three weeks.

Hole APR-18 was a "scout" hole drilled at the southeast corner of April Pond (Fig. 2), the first of six sites that are being tested with shallow holes (average 150 m at -45°) prior to returning to last year's Discovery Zone (7.1 m grading 2.75 g/t Au, 40.2 g/t Ag, 0.30% Zn and 0.28% Pb); see Tower's May 06, 2020 press release) and drilling it off systematically at 50 m intervals. The objective of each scout hole is listed in Table 1. The rationale for drilling these holes first is to ensure that the available metres are allocated to the best targets, as the 17 earlier holes drilled in 2019 and 2020 demonstrated that multiple gold zones are present within a 500 x 1000 m area surrounding April Pond. The initial results obtained from Hole 18 clearly validate this reasoning.

Table 1 - Locations and objectives of the six scout holes. Approximately eighteen holes are planned.

The new mineralized zone in Hole 18 is 350 m across strike from the Discovery Zone. It occurs at a shallow depth of just 100 m and, based on the high Au-Ag-As content of the overlying glacial till, probably extends to surface. Ironically, it lies directly beneath a clearing that Placer Dome used as a campsite in 1992 while drilling the porphyry Cu mineralization of the historical C-Zone (Fig. 2).

The gold mineralization of the new zone occurs in strongly altered, sulphidized, brecciated (Fig. 3) and stockwork-veined (Fig. 4) siltstone proximal to a strongly pyritized biotite-feldspar porphyry body that was intersected in the final reverse circulation (RC) drill hole, No. 92, of Tower's 2017-2020 till sampling programs. The main sulphide minerals are pyrite and pyrrhotite with 0.5 to 2% arsenopyrite, the principal gold associate at Nechako. Only minor sphalerite, the principal silver associate, is present. Therefore, the Ag concentration (7.2 g/t; Table 2) is not as high as in the more sphalerite-rich Discovery Zone.

The Au concentration in the seven analyzed samples is very consistent, ranging from 1.14 to 5.91 g/t (Table 2), and the average 2.0 g/t grade of the 7.3 m section is not unduly influenced by any one sample. That is, the entire section is significantly mineralized; there is no detrimental nugget effect and no need to "cut'' any gold assays.

Table 2 - Au and Ag analyses for the first 7.3 m of the new 10.5 m wide gold zone in Hole APR-18.

Stu Averill, P.Geo., a Company Director, commented: "Having learned the mineralizing controls at Nechako step-by-step from our previous drilling programs, we are now hitting mineralization more predictably and thus more frequently and at an increasingly larger scale. Our new discovery in Hole 18 is both an example of this progress and a portent of the possibilities that lie ahead."

Methods and Qualified Person

The drill holes are being logged by Mr. Dane Bridge, MSc., P.Geo., a seasoned mineral exploration geologist with extensive experience on the Nechako Gold property.

Split samples of the DD core, generally 1-2 m in length, are prepared at Tower's core logging facility at Tatelkuz Ranch near the Nechako property. Each sample is then prepared for analysis and analyzed at Activation Laboratories (ActLabs) in Kamloops, BC, a laboratory certified as ISO/IEC 17025 Accredited (Lab 790) by the Standards Council of Canada. The samples are analyzed for gold by fire assay and ICP-OES and for 37 further elements, including Ag, As, Zn, Pb and Cu, by ICP-OES using a four-acid, near-total digestion. Over-limit (>5 g/t Au, >100 g/t Ag, >1% As, Zn or Cu, >0.5% Pb) analyses are repeated using the same procedures but at a higher detection range. QA/QC samples including blanks and standards are inserted regularly into the sample sequence at a ratio of approximately 1:15.
