Trinity One Metals Ltd. Identifies Historic High Grade Silver Intercepts At Silver-1
Trinity One Metals Ltd. announced the compilation and initial interpretation of six historic diamond core drill holes completed at the Company's Silver-1 Mine in Ecuador as part of a United Nations exploration program in 1978. The reported results are from the previously mined Ocashuaico sector. The Company has also located additional historic drill logs from the Shunaste sector, where no historical mining is known to have occurred. These records, which are not included in the current release, are undergoing verification and geological interpretation. The drilling was completed approximately 11 years before underground mining commenced at Silver-1 in 1989. Historical information indicates that mining continued until approximately 1994 and reached a reported maximum depth of approximately 90 m. The newly compiled records include high grade silver-lead-zinc intersections at calculated vertical depths exceeding the reported maximum depth of historical mining. Notably, Ocashuaico hole SB-18 intersected a principal high grade zone beginning at 152.15 m downhole. The records were recovered by the Company's in-country geological team through a systematic review and digitisation of original paper drill logs and technical documents held in the archives of Ecuador's Geological and Energy Research Institute (Instituto de Investigación Geológico y Energético, or "IIGE"). The results provide Trinity One with an important new dataset for evaluating the potential continuation of high grade mineralisation beneath and surrounding the historical Silver-1 mine workings. Ocashuaico hole SB-18: 2.60 m at 36.16 oz/t silver (1,240 g/t), 1.57% lead and 3.08% zinc from 152.15 m (107.6 m VD), including: 0.25 m at 233.40 oz/t silver (8,002 g/t), 7.80% lead and 11.70% zinc from 154.50 m (109.2 m VD). Ocashuaico hole SB-19: 0.50 m at 60.56 oz/t silver (2,076 g/t), 1.66% lead and 5.00% zinc from 48.20 m (34.1 m VD); 5.30 m at 5.30 oz/t silver (182 g/t), 0.69% lead and 1.44% zinc from 55.00 m (38.9 m VD); 0.15 m at 65.00 oz/t silver (2,229 g/t), 1.46% lead and 9.00% zinc from 131.05 m (92.7 m VD); and 0.23 m at 29.48 oz/t silver (1,011 g/t), 1.74% lead and 11.10% zinc from 155.12 m (109.7 m VD). Ocashuaico hole SB-20: 5.45 m at 6.33 oz/t silver (217 g/t), 0.35% lead and 1.35% zinc from 38.35 m (27.1 m VD), including: 0.97 m at 22.00 oz/t silver (754 g/t), 0.82% lead and 3.80% zinc from 38.35 m (27.1 m VD). 0.40 m at 10.20 oz/t silver (350 g/t), 2.80% lead and 1.90% zinc from 164.40 m (116.2 m VD). Holes SB-18, SB-19 and SB-20 as shown in the diagram above were drilled at a dip of approximately -45 degrees. For the purposes of this release, vertical depth below the drill collar ("VD") has been calculated using this approximate drill inclination and assumes no material drill hole deviation. The calculated vertical depths of multiple mineralised intersections, including the principal high grade zone in SB-18, are numerically greater than the approximate 90 m maximum mining depth reported in the available historical records. Several of the deeper intersections occur across multiple drill holes, providing a number of distinct targets for further geological interpretation and modern exploration. Results from the remaining three Ocashuaico holes were generally of a lower grade than the highlighted intersections. SB-25 returned 1.90 m grading 3.64 oz/t silver (125 g/t) from 127.70 m, SB-25B returned trace silver in the two recorded sample intervals, and SB-27 returned 1.50 m grading 1.88 oz/t silver (64 g/t) from 229.00 m. The results reported in this release were compiled from original paper records held by IIGE and checked by the Company's geological team against the available historical figures and drill information. The Company has not independently verified the results through resampling of original drill core or confirmation drilling. The available records do not identify the analytical laboratory, analytical methods, sample preparation procedures, core diameter, sample security protocols, or complete information regarding drilling procedures, core recovery and QA/QC. Accordingly, the historical results should not be treated as equivalent to results generated under current exploration and analytical standards. The Company nevertheless considers the records relevant and sufficiently reliable to guide ongoing geological interpretation and exploration planning. Silver values originally reported in ounces per ton have been converted to grams per tonne using a conversion factor of 34.2857 grams per tonne for each troy ounce per short ton. Reported widths are historical sampled or downhole widths, and true widths have not yet been determined. Composite grades are length weighted averages calculated using the recorded from-and-to depths of the constituent historical sample intervals. The historic collar survey records, drilling orientations, total depths and coordinates in WGS 84 /UTM 17S, for the Ocashuaico drill holes are as follows: Drill hole Easting (m) Northing (m) Collar elevation (m ASL) Azimuth Dip Total depth (m) SB-18 738,060 9,667,892 3,135.07 016° -45° 206.96 SB-19 738,074 9,667,974 3,134.00 010° -45° 167.64 SB-20 738,076 9,668,044 3,133.20 008° -45° 211.53 SB-25 738,172 9,668,121 3,194.30 357° -45° 152.40 SB-25B 738,172 9,668,121 3,194.30 001° -45° 365.76 SB-27 738,009 9,668,137 3,131.50 191° -63° 240.20. The scientific and technical information contained in this news release has been reviewed and approved by Enkhtuvshin Khishigsuren, P.Eng., an independent geological consultant to the Company and a Qualified Person as defined by National Instrument 43-101. The Qualified Person reviewed the available historical drill logs and records, the Company's compilation and transcription of those records, and the calculations and conversions presented in this news release. The Qualified Person has not independently verified the historical drilling results through resampling of original drill core or confirmation drilling. Information concerning certain historical drilling, sampling, analytical and quality-control procedures is incomplete. Accordingly, the historical results will require confirmation through systematic modern exploration and drilling incorporating appropriate QA/QC procedures.
