("Osino" or the "Corporation") have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an exemption from registration. This presentation shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities of Osino in any jurisdiction in which such offer, solicitation or sale would be unlawful. This presentation does not constitute an "offering memorandum" as such term is defined under Canadian securities legislation and confers no statutory, contractual or other similar rights of rescission or other action or remedy to any recipient under securities legislation in Canada, the United States or other jurisdiction for misrepresentation or otherwise. This presentation does not provide full disclosure of all material facts relating to the Corporation. Readers should conduct their own analysis and review of the Corporation and of the information contained in this presentation and should contact their own professional advisors. For additional information, the readers are directed to the Corporation's current technical report and other corporate and financial disclosure filed under the Corporation's profile on SEDAR at www.sedar.com. This presentation contains "forward-looking information". Forward-looking information includes, without limitation, statements regarding macroeconomic factors, future demand and supply dynamics, forecasts and timelines, exploration, development and production activities, including information regarding the potential mineralization and mineral resource estimates, ability to obtain financing, future currency exchange rates, government regulation of mining operations, and environmental risks. Similarly, forward-looking information also includes all statements other than statements of historical fact contained in this presentation, including, without limitation, those regarding the Corporation's future financial position and results of operations, strategy, plans, objectives, goals and targets, future developments in the markets where the Corporation participates or is seeking to participate. In general, forward-looking information can be identified by the use of forward-looking terminology such as "plans", "expects", "believe", "expect", "aim", "intend", "plan", "continue", "will", "may", "would", "anticipate", "estimate", "forecast", "predict", "project", "seek", "should" or similar expressions or the negative thereof. Forward-looking statements are not historical facts but instead represent only the Corporation's expectations, estimates and projections regarding future events. These statements are not guarantees of future performance and involve assumptions, risks and uncertainties that are difficult to predict. Therefore, actual results may differ materially from what is expressed, implied or forecasted in such forward-looking statements. Such forward-looking information is based upon factors and assumptions the Corporation and its consultants believe is reasonable based on information currently available to them. By its nature, forward-looking information involves known and unknown risks, uncertainties and other factors which may cause actual results, performance or achievements, or industry results, to differ materially from those expressed or implied by such forward-looking information. The preliminary economic assessment reflected in this presentation is from the Company's current technical report (the "Current PEA") on its Twin Hills Gold Project in Namibia which is referred to in this presentation and is the technical report most recently filed on SEDAR at www.sedar.com under the Company's profile. This preliminary economic assessment is preliminary in nature, as it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. The Current PEA sets out the basis for the preliminary economic assessment and any qualifications and assumptions made by the qualified persons responsible for the Current PEA. The most pertinent assumptions and qualifications, other than as noted above, are that the economic analysis was based on a foreign exchange rate of USD1.00 = $15.5 Namibian dollars and base case gold price of USD$1,700/oz gold, as well as the following parameters: 15-year LOM, 5.0% mining dilution, 3.5% mineralized material loss, 90.9% gold recovery, 3.0% royalty, and 1.0% export levy (please see Current PEA for further details). The reader is cautioned that any reference to mineral resources or geological technical information about Osino's mineral properties is based on, excerpted from and expressly qualified by Osino's current technical report (the "Technical Report") which was prepared in accordance with NI 43-101 entitled, "Twin Hills Gold Project, Namibia, NI 43-101 Technical Report" signed May 10, 2021 dated effective April 1, 2021 by Anton Geldenhuys, MEng, MGSSA, PrSciNat #400313/04 of CSA Global South Africa (Pty) Ltd. and Graham Hetherington, BEng, MAusIMM #318140 of Lycopodium Minerals Africa, (Pty) Ltd. prepared for Osino Resources Corp. Accordingly, Osino recommends that the reader refer to and read the Technical Report in its entirety, a copy of which is available on SEDAR at www.sedar.com under Osino's issuer profile. 2#3Ownership & Share Structure Share Structure Shares Basic (m) Shares FDITM (m) 09 November 2021 110,1 128,4 ITM Share Options (m) ITM Warrants (m) 8,9 9,4 38, 30, 80, 120 cps 105 cps Share Price (12m H/L) $1.65/$0.43 Retail & HNW 29% Insiders & Associates 36% Cash in treasury (C$m) ITM warrants cash (C$m) 14,1 8,5 Projected Dec-21 Market Cap (C$m) 143,1 09 Nov 21 110.1m Shares Research Coverage Target (C$) Analyst issued & outstanding Cormark 3.20 Richard Gray M Partners 2.80 Eduardo Perez Sprott 2.75 Brock Salier IA Financial Group 2.60 George Topping Beacon Securities Institutions 36% 2.50 Bereket Berhe Stifel GMP 2.30 Alex Terentiew Echelon Wealth 2.20 Ryan Walker Consensus Target: 2.62 20% 0% -20% -40% -60% Jan 2021 Source: Google Finance, Market Data as of July 19, 2021 Relative Share Price Performance: YTD to 06 Nov 2021 Mar 2021 May 2021 Jul 2021 Sept 2021 Nov 2021 OSINO RESOURCES Early-stage Seed Funders: Ross Beaty, Co-Founders, RCF RESOURCE CAPITAL FUNDS ASSOCIATES Invesco MACKENZIE Investments Earth Resource Investment Group * Rothschild & Co IXIOS ●●● Asset Management MERK | Osino Resources C... $1.25 ↓ 1.57% | VanEck Vectors Ju... $38.32 ↓ 17.50% |B2Gold Corp. $5.43 ↓ 35.20% 3#4Namibia: A Premier Mining Jurisdiction STABLE & MINING FRIENDLY Stable democracy, independent judiciary, fairly diverse economy (tourism, mining, fishing & agriculture) Serra Catema Transparent system of mineral & surface title Man Skeleton Political and social support of mining with stated ambitions to develop mineral resources SKELETON COAST PARK ANGOLA OSINO RESOURCES ZAMBIA MUDUMU NATIONAL PARK River Kunene RUACANA KAOKOLAND BWABWATA NATIONAL PARK Susuwa KATIMA MULILO imp isla Island Lodge KI Kavango (Okavango)Riser RUNDU ETOSHA NATIONAL PARK Namutanl MAHANGO NATIONAL PARK SESFONTEIN TSUMEB Okaukuejo KHAUDUM NATIONAL PARK Nxamasen Lodge Lianshule Lodge MAMILI NATIONAL PARK Coast Camp Golosite Cam Naial GROOTFONTEIN Terrace Bay DAMARALAND Etendeks KHORIXAS homa TSUMKWE Mandatea OUTJO N Cape Cross AMIB Vingerklip OT JIWARONGO Truytelfontein WATERBERG NATIONAL PARK OKAVANGO DELTA MAUN Th OMARURU Erange KAHANDJA Twin Hills Gold Project Osino BOTSWANA See pages 84-113 GOBABIS WINDHOEK Eninge KALAHARI DESERT Sesriem Naukluft Mauniain Bagafelle NAROMA DANS MARIENTAL Sossusviel Mata Mata NAMIB NAUKLUFT PARK Namib Rand Reserve KGALAGADI TRANSFRONTIER PARK EXCELLENT INFRASTRUCTURE & LOCATION Excellent physical & social infrastructure Within 20km's of essential utilities: paved roads, national power grid, water supply & well-serviced local towns Vast landscapes & unique cultures WELL-ESTABLISHED MINING INDUSTRY SWAKOPMUND WALVIS BAY Mining is major revenue earner & formal sector employer in Namibia (8% of GDP, 40% of foreign earnings) Significant production of diamonds, gold & uranium DESERT LUDERITZ Current & former in-country mining producers (gold, diamonds, uranium, copper and industrial metals): Sinclair/Dabi AUS KEETMANSHOOP RIETFONTEIN FISH Fish Wir RIVER Lodge CANYON ERUNAU Calon Lodgy Ai-Ais THE SPERRGEBIET Orange River SPRINGBOK Expert Africa 2012 UPINGTON SOUTH AFRICA Dundee QKR NAMIBIA NAVACHAB GOLD MINE GCGN orano CNS Teck Rio Tinto Newmont vedanta AngloAmerican Trevali ANGLOGOLD ASHANTI resources plc B2GOLD NA MDEB PRECIOUS METALS MINING COSECRATION PALADIN ENERGY LTD 4#5Namibia: Tectono-Stratigraphic Setting Damara Orogenic Belt ■Structurally controlled ■ Sediment-hosted Au deposits Large tonnage / lower grades often simple metallurgy Orogenic Exploration Model ■ Source ■ Pathway Traps Neoproterozoic Analogues Haile, USA Otjikoto, Namibia ■ Sukari, Egypt Excellent regional exploration potential Oshakati Opuwo EKZ NP KZ KT Khonxas Gase ne ob Thrust NZ Outjo Rundu Grootfontein Lineament Tsumeb Olavi fontem Otjiwarofgr OSINO RESOURCES Katima Mulilo Reference Tectonostratigraphic zones Late Proterozoic to Neogene cover sequences Coastal Terrane (Damara; CT) Western Kaoko Zone (Damara; WKZ) Central Kaoko Zone (Damara; CKZ) Eastern Kaoko Zone (Damara; EKZ) Southern Kaoko Zone (Damara; SKZ) Northern Platform (Damara; NP).

Bedrock testing via percussion fence line drilling over high grade calcrete anomaly; tight correlation with surface calcrete values validates the use of 'top of calcrete' as a sample medium; several bedrock assays over 0.5g/t with a peak value of 2.69g/t Gold anomalies are spatially coincident with magnetic anomalies in data collected during Q4 2018; causative body for magnetic anomalies is pyrrhotite mineralization in hydrothermally altered quartz biotite schist Most prospective portion of TH prospect is a structural jog on the margin of the Dobbelsberg dome; Three magnetic splays, coincident with anomalous gold assays are visible in the jog, with a combined width of over 1km Recent confirmatory work (bedrock percussion drilling) and strike & width expansion was completed before 7-hole diamond drill program resulted in Twin Hills Central discovery 25 25#26Geology & Mineralization OSINO RESOURCES Cm-scale quartz sulphide veins in schist Brecciation and silicification in quartzite Pyrrhotite Pyrrhotite in brecciated quartz vein Arsenopyrite Arsenopyrite in cm scale veinlet in schist Pyrite Sediment-hosted, orogenic (structurally controlled) Au deposit Thick package of turbidites and calcareous sediments were buried and deformed during the late Proterozoic Damara orogeny Metal bearing brines were expelled from the deep sedimentary basin and driven towards the southern margin which is defined by a basement cored anticline Hydrothermal fluids were channelled upwards in the basin margin fault and out into the lower stress splay structures Gold deposition mainly in a zone of intense folding and faulting adjacent to the basin margin. Host rocks include biotite and muscovite schist (Au in quartz- sulphide veins parallel or sub-parallel to foliation) and quartzite and turbidite (Au in breccia, stockwork and cross cutting quartz - sulphide veins) Gold mineralization is associated with three sulphide phases, namely pyrrhotite, arsenopyrite and pyrite Several zones of pervasive alteration and replacement by silica- rich fluids and sulphides have been intersected. These replacement zones appear to host higher gold grades Detailed petrography & mineralogy samples submitted for better understanding of the Au associations and deportment.
