Vancouver, British Columbia--(Newsfile Corp. - September 7, 2023) - Tincorp Metals Inc. (TSXV: TIN) (OTCQX: TINFF) ("Tincorp" or the "Company") is pleased to announce that it has received the assay results for holes DPOV0002, DPOV0003, DPOV0004 and DPOV0006 from its Porvenir tin-zinc-silver (Sn-Zn-Ag) Project (the "Project"). Tincorp completed seven drill holes totaling 2,545 m for its 2023 drill campaign at the Project.

These four holes and the previously reported DPOV0001 were drilled to test the depth and lateral extension of the NNW-trending Condor Nasa structure (NWV1) and the NS-trending mineralized structures (NSV1 and NSV2, Fig. 1).

The assay results are highlighted by a 21.20 m intercept grading 334 g/t silver equivalent (AgEq) (0.65% Sn, 1.97% Zn, 4 g/t Ag and 0.10% Cu) in hole DPOV0006, which includes 828 g/t AgEq (1.71% Sn, 4.21% Zn, 7 g/t Ag and 0.16% Cu) over 6.13 m. This represents the mineralization of the NNW-trending Condor Nasa structure (Fig. 1 & 2). Figure 3 illustrates a high-grade section of DPOV0006.

In addition to the results of DPOV0006, the composite assay results are shown in Table 1 below:

Table 1. Composite assay results for hole DPOV0002, DPOV0003, DPOV0004 and DPOV0006.

Notes:
1. Drill intercepts are core lengths, and grades are length-weighted. The true width of mineralization is unknown at this time.
2. Analyses were from half-core samples, cut by diamond saw and collected from the entire hole.
3. Silver equivalent (AgEq g/t) is shown for illustrative purposes only to express the combined value of tin, zinc and silver as a grade of silver. AgEq is calculated using US$0.74 per gram of silver, US$2755 per tonne of zinc, US$8816 per tonne of copper and US$28000 per tonne of tin. Metal recoveries are not yet known.
4. The silver equivalent formula used was: AgEq g/t =Ag grade + ((Pb%*2094/100)+(Zn%*2755/100)+(Cu%*8816/100)+(Sn%*28000/100))/0.74

Other than the high-grade interval in DPOV0006, DPOV0003 and DPOV0004 also drilled through NWV1 (Fig. 1), with DPOV0003 intersecting 36.72 m of 113 g/t AgEq (0.17% Sn, 0.92% Zn, 5 g/t Ag and 0.08% Cu) and DPOV0004 intersecting 9.77 m of 115 g/t AgEq (0.08% Sn, 1.29% Zn, 16 g/t Ag and 0.17% Cu).

The 10.18 m high-grade interval in DPOV0002 (294 g/t AgEq, 0.25% Sn, 4.14% Zn, 25 g/t Ag and 0.16% Cu) and 10.80 m interval of DPOV0003 (361 g/t AgEq, 0.40% Sn, 4.43% Zn, 20 g/t Ag and 0.21% Cu) are related to the NS-extending vein, NSV1 (Fig.1).

The 3.52 m interval of 361 g/t AgEq (0.72% Sn, 1.72% Zn, 9 g/t Ag and 0.11% Cu) in DPOV0003 is related to NSV2 (Fig. 1).

DPOV0002, DPOV0003 and DPOV0004 have intercepted multiple NS-trending mineralized structures (NSV1 and NSV2) which has opened up new drilling targets to be tested in future drill programs at the Project.

Mineralization in the holes occurs as sulfide and gangue minerals permeated in veins, veinlets and breccias. The sulfide minerals recognized to date are predominantly pyrite, pyrrhotite, and sphalerite with lesser amounts of galena, chalcopyrite, and arsenopyrite. Sericite, siderite, and quartz are the predominant gangue minerals, though they form a minor portion of the mineralized zone. The mineralization is hosted within a chlorite-sericite altered shale and argillite sequence of the Silurian-aged Llallagua Formation.

"We are thrilled by the outstanding assay results from our recent drill campaign at the Porvenir Project. I am excited to witness the continued success of Tincorp's exploration efforts. These results confirm our belief in the richness of the mineralization at Porvenir and reinforce our commitment to unlocking the full value of this remarkable asset," stated Mr. Gordon Neal, CEO of Tincorp.

Quality Assurance and Quality Control
Tincorp maintains tight sample security and quality assurance and quality control for all aspects of its exploration program. All Porvenir core samples were logged, photographed and split on-site 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 Ltda., in Oruro, Bolivia, for preparation, and ALS Peru laboratory in Lima, Peru for geochemical analysis. ALS Global is an ISO 17025 accredited laboratory independent from New Pacific. All samples are first analyzed by a multi-element ICP package (ALS code ME-MS41) with ore grade specified limits for silver, lead, and zinc, further analyzed using ALS code OG46. The tin grades were analyzed by fusion XRF (ALS code ME-XRF15b). Certified reference materials, various types of blank samples and duplicate samples are inserted into normal drill core sample sequences prior to delivery to the laboratory for preparation and analysis. The overall ratio of quality control samples in sample sequences is around twenty percent.
