Tincorp Announces Assay Results of Historic Cores from Its Porvenir Project in

Bolivia Including 60.20 m Grading 0.66% Tin or 322.8 g/t AgEq

Vancouver, British Columbia – March 2, 2023 – Tincorp Metals Inc. (“Tincorp” or the

“Company”) (TSXV: “TIN”; OTCQX: “TINFF”) is pleased to announce that it has received the first

two batches of assay results of historic core samples from its Porvenir tin-zinc-silver (Sn-Zn-Ag)

Project (the “Project”), located in the west-central region of Bolivia, 65 kilometers (“km”) southeast

of the city of Oruro. The highlight results were received from hole PV-41 with an intercept of 60.20

meters (“m”) grading 0.66% tin, 1.44% zinc, and 6.30 g/t silver totaling 322.8 g/t AgEq.

As previously reported (see news release dated August 31, 2022), the Company has the rights to

acquire a 100% interest of the Porvenir Project. The Property was subjected to some small-scale,

historic mining and was explored and drilled by Japanese mining company, Dowa Metals and

Mining Company (“Dowa”) from 2007 to 2011. In total, Dowa completed 88 diamond drill holes

totaling approximately 25,000 m of core based on the data acquired by the Company from an

independent source. However, only 918 m of core had been sampled and assayed by Dowa

previously.

Samples were collected from recovered historic core, and the new ly received assays have

confirmed historic mineralization intercepts (Table 4 and Table 5) and further indicated that the

mineralization is more extensive down -hole. From October to December 2022, over 1,300 m of

historic core from 37 holes have been recovered, relogged and sent for assay, including 1, 391

samples. There remain another 679 assays for the company to report.

Mr. Gordon Neal, CEO of the Company stated, “The results of our sampling and assaying program

to date are encouraging, as Tincorp 's results closely correlate with the historic assays and has

shown tin mineralization is more extensive in each hole sampled than was indicated in the historic

data. The relogging and assaying program on historic core was completed in 2022 and we are

expecting more assays in the next few weeks.”

The most encouraging results are from holes PV-41 and PV-26.

PV-41 has a total hole length of 355 m . 82.20 m of core have been recovered and assayed,

including the intervals between 220-235 m and 265-332.2 m. High-grade mineralization intervals

in this hole are composed of massive sulfides of sphalerite, pyrrhotite and pyrite, along with

silicification. The new assays reveal ed a 60.2 m wide continuously mineralized interval grading

0.66% Sn and 1.44% Zn and another 10.6 m wide interval grading 0.24 % Sn and 2.57 % Zn.

PV-26 has a total hole length of 250.75 m, and 39.00 m of core have been recovered and assayed

(from 133.70 to 172.70 m). High- grade intervals are composed of patches of sulfide (pyrrhotite -

sphalerite) hosted in bleached sandstone. The new assay results have revealed a 16.7 m wide

continuously mineralized interval of 0.64 % Sn and 0.70 % Zn.

The newly received assays are consistent with the historic Dowa assays, which suggests the

historic assays data are reliable to provide guidance for future exploration. The comparison of

historic Dowa assays and the newly received assays of PV-41 and PV-26 are shown in Table 4

and Table 5.

Quality Assurance and Quality Control

Dowa assays were on ¼ core . Tincorp resampled another ¼ core for direct comparison. O n

unsampled Dowa core, Tincorp used ½ core - all of which were obtained with a diamond -

impregnated core saw.

All Porvenir core samples were collected by staff geologists and were shipped in securely sealed

bags by Company staff in the Company’s vehicles, directly from the field to ALS Bolivia Ltd., in

Oruro, Bolivia for preparation, and ALS Peru laboratory in Lima - Peru for geochemical analysis.

The global quality program includes internal and external inter -laboratory test programs and

regularly scheduled internal audits that meet all requirements of ISO/IEC 17025:2017 and ISO

9001:2015. The ISO 17025 Accreditation proves a laboratory has an acceptable quality

management system in place, and it has the ability and competence to provide testing and

calibration results. All samples ar e prepared using the ALS code: PREP -31; analyzed by ME -

MS41 - multi-elemental by aqua regia - ICP-MS - Ultra Trace Levels; for tin: Sn-XRF15B: Fusion

Lithium Metaborate - XRF termination . For over limits, digestion in aqua regia is used and

finalization by ICP-AES (OG 46 series).

Two types of certified reference materials (standards) are inserted: one, from CDN Resource

Laboratories Ltd., and another from OREAS - Ore Research & Exploration P/L; additionally,

control samples such as thick white samples and duplicate samples are inserted into normal

sequences of drill core samples before sending to the laboratory for preparation and analysis.

The overall ratio of quality control in sample sequences is minimum ten percent.

factors and estimates which may prove to be incorrect, include, but are not limited to: whether the Company

will acquire up to a 100% interest of the Porvenir Project; market fundamentals will result in sustained

precious metals demand and prices; that there are no significant disruptions affecting operations, including

labour disruptions, supply disruptions, power disruptions, security disruptions, damage to or loss of

equipment, whether due to flooding, political changes, title issues, intervention by local landowners,

environmental concerns, pandemics (including COVID -19) or otherwise; that the Company will be able to

obtain and maintain governmental approvals, permits and licenses in connection with its current and

planned operations, development and exploration activities, including at the Skukum Gold Project; that the

Company will be able to meet its current and future obligations; that the Company will be able to comply

with environmental, health and safety laws; and the assumptions underlying mineral resource estimates

and the realization of such estimates.

Forward-looking statements involve known and unknown risks, uncertainties and other factors which may

cause the actual results, performance or achievements of the Company to differ materially from any future

results, performance or achievements expressed or implied by the forward- looking information. Such risks
