Vancouver, British Columbia--(Newsfile Corp. - August 16, 2023) - Tincorp Metals Inc. (TSXV: TIN) (OTCQX: TINFF) ("Tincorp" or the "Company") is pleased to announce the first drill hole assay results for the Porvenir tin-zinc-silver (Sn-Zn-Ag) Project (the "Project"), Oruro, Bolivia. Tincorp is in the process of completing seven drill holes totaling 2,500 m for its 2023 drill program at the Project.

Hole DPOV0001 intercepted 284 g/t silver equivalent (AgEq) (0.60% Sn, 1.11% Zn, 6 g/t Ag, and 0.07% Cu) over 120.35 m including 1022 g/t AgEq (2.25% Sn, 3.35% Zn, 21 g/t Ag, and 0.20% Cu) over 21.62 m.

The principal objective of this first phase of Tincorp's drilling was to test the depth and lateral extension of the NNW-trending Condor Nasa structure. Condor Nasa is evident in Figure 1 by the alignment of historic workings and labeled as NWV1. In addition to encountering mineralization in NWV1, drilling also intersected several other veins, in the hanging wall and footwall of NWV1, interpreted to be NS-trending structures (NSV, NSV1, NSV2). Hole DPOV0001 is a 25 m down-dip step-out of historic Dowa Mining drill hole PV-41 (0.66% Sn, 1.44% Zn, and 6 g/t Ag or 322.8 g/t AgEq over 60.2 m).

In addition to the main NWV1, there are multiple north-south veins (NSV1 and NSV 2) (Table 1), which will open up more drilling targets, therefore, more potential for the Project. The highest interval of 1022 g/t AgEq (2.25% Sn, 3.35% Zn, 21 g/t Ag, and 0.20% Cu) over 21.62 m is related to the new north-south extending vein, NSV2, which corresponds to extensive historical surface diggings (see Figures 1 & 2). Figure 3 illustrates a high-grade section of DPOV0001.

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%*2575/100)+(Cu%*8816/100)+(Sn%*28000/100))/0.74

Mineralization in DPOV0001 occurs as sulfide and gangue minerals in veins, veinlets and breccias. The sulfide minerals recognized to date are dominantly 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.

Mr. Gordon Neal, CEO of Tincorp, said: "We are excited with these exceptional assay results from our inaugural drill hole, DPOV0001. Our drilling has uncovered new mineralized NS zones adjacent to our main NW, Condor Nasa vein. We believe these initial results, from the first of our seven planned holes, suggest potential for new mineralization proximal to the historic Condor Nasa structure."

Quality Assurance and Quality Control (QAQC)

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). Company protocols included the addition of QAQC samples, consisting of Certified Reference Materials (CRMs), blanks and duplicates, inserted in the sample stream and a rate of 15 QAQC samples per 100 half-core samples (15%).
