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

Bolivia Including 58.25 m Grading 0.22% Tin

Vancouver, British Columbia – April 3, 2023 – Tincorp Metals Inc. (“Tincorp” or the “Company”)

(TSXV: “TIN”; OTCQX: “TINFF”) is pleased to announce that it has received the last three 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 -44 with an intercept of 58.25 meters

(“m”) grading 0.22% tin, 1.22% zinc, and 9.6 g/t silver totaling 130.1 g/t AgEq.

As previously reported in the 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 the 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 and only 1,315 meters of historic core was available for inspection and re-assaying by the

Company.

Samples were collected from the available historic core, and the newly received assays indicate

that the mineralization is more extensive down-hole compared with the mineralization revealed

by the historic assays . 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. All the assay

results have been received , and 712 results have been previously reported (see news release

dated March 2, 2023).

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

continue to provide encouraging results. Tincorp's results show tin mineralization is more

extensive in each hole sampled and closely correlates with the historic assays completed by

Dowa.”

PV-44 has a total hole length of 310.5 m, 68.7 m of core has been recovered and assayed,

including the intervals between 208.5 m to 217.5 m and 229.8 m to 289.5 m. Nearly all the

recovered core are mineralized. Intervals of high-grade Sn are composed of patches of sulfide

(pyrrhotite-sphalerite-pyrite) hosted in bleached sandstone. The new assays revealed a 58.25 m

wide continuously mineralized interval grading 0.22% Sn and 1.22% Zn, which includes a 15.50

m high-grade interval grading 0.52% Sn and 1.22% Zn. Another 5.50 m wide mineralized interval

has also been revealed in the hole, which has a grade at 0.16 % Sn and 1.22 % Zn.

Quality Assurance and Quality Control (QAQC)

Dowa assays were on ¼ core . Tincorp resampled remaining, available ¼ core for direct

comparison. On 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 AL S 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 certifies that 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 are prepared using the following ALS codes: 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 ( CRM standards) were inserted: one from CDN

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

additionally, other control samples and duplicate samples were inserted into normal sequences

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

overall ratio of QAQC samples to normal drill core samples submitted was 1 to 10.
