CAUTIONARY STATEMENT ON FORWARD-LOOKING INFORMATION

This offering document contains "forward-looking statements" or "forward-looking information" within the meaning of applicable Canadian securities legislation. Such statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company, or its mineral projects, or industry results, to be materially different from any future results, expectations, performance or achievements expressed or implied by such forward-looking statements or information. Such statements can be identified by the use of words such as "may", "would", "could", "will", "intend", "expect", "believe", "plan", "anticipate", "estimate", "scheduled", "forecast", "predict" and other similar terminology, or state that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved although not all forward-looking statements contain such identifying words. These statements reflect the Company's current expectations regarding future events, performance and results based on information currently available and speak only as of the date of this offering document. In making such statements or providing such information, the Company has made assumptions regarding, among other things: (i) the accuracy of the estimation of mineral resources; (ii) that exploration activities and studies will provide results that support anticipated development and extraction activities; (iii) that studies of estimated mine life and production rates at its mineral projects will provide results that support anticipated development and extraction activities; (iv) that the Company will be able to obtain additional financing on satisfactory terms, including financing necessary to advance the development of its projects;

(v) that infrastructure anticipated to be developed or operated by third parties, including electrical generation and transmission capacity, will be developed and/or operated as currently anticipated; (vi) that laws, rules and regulations are fairly and impartially observed and enforced; (vii) that the market prices for gold and silver remain at levels that justify development and/or operation of any mineral project; (viii) general economic conditions; (ix) that labour disputes, surface rights disputes, access to property, flooding, ground instability, fire, failure of plant, equipment or processes to operate as anticipated and other risks of the mining industry will not be encountered; (x) competitive conditions in the mining industry; (xi) title to mineral properties; (xii) changes in laws, rules and regulations applicable to the Company; (xiii) that the Company will be able to obtain, maintain, renew or extend required permits; (xiv) the Company's expectations with respect to the terms of the Offering; (xv) the Company's expectations with respect to the use of proceeds and the use of the available funds following completion of the Offering; (xvi) timing in respect of the Qualifying Expenditures; (xvii) the completion of the Offering and the expected Closing Date; and (xviii) the Company's expectation in respect of the Re-Offering and any sales of Secondary Shares. All other assumptions contained in this offering document constitute forward-looking information.

Forward-looking statements involve significant risks and uncertainties, should not be read as guarantees of future performance or results, and will not necessarily be accurate indicators of whether or not such results will be achieved. A number of factors could cause actual results to differ materially from the results discussed in the forward-looking statements, including, but not limited to, unexpected changes in laws, rules or regulations, or their enforcement by applicable authorities, including potentially arbitrary action; the failure of parties to contracts with the Company to perform as agreed; social or labour unrest; changes in commodity prices; effects of pandemics, wars, terrorism or acts of god; unexpected changes in the cost of mining consumables; and the failure of exploration programs or current or future economic studies to deliver anticipated results or results that would justify and support continued exploration, studies, development or operations. New risks may emerge from time to time and the importance of current factors may change from time to time and it is not possible for the Company to predict all such factors, changes in such factors and to assess in advance the impact of such factor on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward- looking statements contained in this offering document. Further risks, uncertainties and assumptions include, but are not limited to, those applicable to the Company and described in the Company's annual information form for the year ended December 31, 2024, which is available on the Company's profile on the System for Electronic Data Analysis and Retrieval (SEDAR+) at www.sedarplus.ca.

Information concerning the interpretation of drill results also may be considered forward-looking statements, as such information constitutes a prediction of what mineralization might be found to be present if and when a project is actually developed. This offering document also contains references to estimates of mineral resources. The estimation of mineral resources is inherently uncertain and involves subjective judgments about many relevant factors. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The accuracy of any such estimates of mineral resources is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation (including estimated future production from the Company's mineral projects, including the Kitsault Valley Project, the anticipated tonnages and grades that will be mined and the estimated level of recovery that will be realized), which may prove to be unreliable and depend, to a certain extent, upon the analysis of drilling results and statistical inferences that may ultimately prove to be inaccurate. Mineral resource estimates may have to be re-estimated based on, among other things: (i) fluctuations in silver, gold or other mineral prices; (ii) results of drilling; (iii) results of metallurgical testing and other studies; (iv) proposed mining operations, including dilution; (v) the evaluation of mine plans subsequent to the date of any estimates; and (vi) the possible failure to receive required permits, approvals and licences.

Although the forward-looking statements contained in this offering document are based upon what management of the Company believes are reasonable assumptions, the Company cannot assure readers that actual results will be consistent with these forward-looking statements. The Company's actual results could differ materially from those anticipated in these forward-looking statements, as a result of, amongst others, those factors noted above. Accordingly, readers should not place undue reliance on forward-looking information. These forward-looking statements are made as of the date of this offering document and are expressly qualified in their entirety by this cautionary statement. Subject to applicable Canadian securities laws, the Company assumes no obligation to update or revise the forward-looking statements contained herein to reflect events or circumstances occurring after the date of this offering document.

SUMMARY DESCRIPTION OF BUSINESS

What is our business?

Dolly Varden is a mineral exploration company focused on exploration in the Golden Triangle region of northwestern British Columbia. The Company holds a 100% interest in the Kitsault Valley Project (being the combined Homestake Ridge Project and Dolly Varden Project), among the largest high-grade, undeveloped precious metal assets in Western Canada with a combined mineral resource base of 34.7 million ounces of silver and 166,000 ounces of gold, both in the indicated category, and 29.2 million ounces of silver and 817,000 ounces of gold, both in the inferred category (see the section titled "Scientific and Technical" information below for details regarding the mineral resource base at the Kitsault Valley Project, including tonnes and grade for each category). The Company also holds 100% interest in half of the nearby Big Bulk copper-gold property in addition to an option to own 100% of the southern half of the copper-gold property. The company also retains 100% ownership of the Kinskush property which is contiguous to The Kitsault Valley Project and surrounds the two Big Bulk properties. Outside of the Kitsault Valley, Big Bulk and Kinskuch properties, the Company has 100% interest in the Porter property located 5 kilometers from Stewart, BC. These projects are considered to be highly prospective for hosting high-grade precious metal deposits.

At present, the Kitsault Valley Project, the nearby Big Bulk copper-gold property, the Kinskush property and Porter property are all considered exploration stage projects, and consequently have no current operating income, cash flow or revenues. There is no assurance that commercially viable mineral deposits exist on any of the Company's properties.

The Company's objective is to derisk, expand and discover new high-grade silver and gold mineralization for all of its exploration properties so that defined mineral deposits on the project may be considered for further advancement or development. In order to achieve that goal, certain short, medium and long term business objectives must be met. The net proceeds of the Offering are intended to meet the following near and medium term business objectives:

USE OF AVAILABLE FUNDS

What will our available funds be upon the closing of the Offering?

Based on the Company's existing estimated working capital as at May 31, 2025 of approximately $27 million, the Company's expected availability of funds following closing of the Offering (assuming the Underwriter's Option is not exercised) is expected to be approximately $50.5 million.

How will we use the available funds?

The Company intends to use the net proceeds from this Offering (assuming the Underwriter's Option is not exercised) to complete the business objections and milestones noted above as follows:

The above noted allocation represents the Company's current intentions with respect to its use of proceeds based on current knowledge, planning and expectations of management of the Company. Although the Company intends to expend the proceeds from this Offering as set forth above, there may be circumstances where, for sound business reasons, a reallocation of funds may be deemed prudent or necessary and may vary materially from that set forth above, as the amounts actually allocated and spent will depend on a number of factors, including the Company's ability to execute on its business plan and financing objectives. The Company has generated negative cash flows from operating activities since inception and anticipates that it will continue to have negative operating cash flow until profitable commercial production at one or more of its properties is achieved. As a result, certain of the net proceeds from this Offering may be used to fund such negative cash flow from operating activities in future periods.

Drill core is cut in-half with a diamond saw, with one-half placed in sealed bags and shipped to the laboratory and the other half retained on site. Third party laboratory checks on 5% of the samples are carried out as well. Chain of custody is maintained from the drill to the submittal into the laboratory preparation facility.

Analytical testing was performed by ALS Canada Ltd. in North Vancouver, British Columbia. The entire sample is crushed to 70% minus 2 mm (10 mesh), of which a 500-gram split is pulverized to minus 200 mesh. Multi-element analyses were determined by inductively coupled plasma mass spectrometry (ICP- MS) for 48 elements following a 4-acid digestion process. High-grade silver testing was determined by fire assay with either an atomic absorption or a gravimetric finish, depending on grade range. Au is also determined by fire assay on a 30-gram split with either atomic absorption or gravimetric finish, depending on grade range. Metallic screen assays may be completed on very high-grade samples.

Kitsault Valley Project Mineral Resource Estimate

The Kitsault Valley Project resource estimate is derived from the Kitsault Valley Technical Report.

Notes:

(1) Mineral resources are not mineral reserves, as they do not have demonstrated economic viability although, as per CIM requirements, the mineral resources reported above have been determined to have demonstrated reasonable prospects for eventual economic extraction.

(2) The mineral resources were estimated in accordance with the CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

(3) The resources reported above are derived from the Technical Report on The Combined Kitsault Valley Project, British Columbia, Canada dated effective September 28, 2022 and authored by Andrew J. Turner, B.Sc., P.Geol., of APEX Geoscience Ltd. The effective date of the report is September 28, 2022.

(4) The cut-off grade for the Homestake claim block mineral resources is 2.0 g/t AuEq, which was determined using average block grade values within the estimation domains and a Au price of $1,300 per troy ounce ("/tr oz"), a Ag price of US$20.00/tr oz and a Cu price of US$2.50/pound, and mill recoveries of 92% for Au, 88% from Ag and 87.5% for Cu, and combined mining, milling, and general and administrative costs of approximately US$109/ton.

(5) The cut-off grade for the Dolly Varden claim block mineral resource is 150 g/t Ag, which was determined using a Ag price of US$20.00/tr oz, a recovery of 90% and combined mining, milling, and general and administrative costs of US$80/ton and was supported by comparison to similar projects.

(6) Sufficient sample density data existed to allow for estimation of block density within the estimation domains of the Homestake Main, Homestake Silver and Homestake Reef zones, which ranged from 2.69 metric ton per cubic metre ("t/m3") to 3.03 t/m3.

(7) Bulk density values ranging from 2.79 t/m3 to 3.10 t/m3 were assigned to individual estimation domains based on available SG measurements for the DV, TB, NS and WF deposits.

(8) Differences may occur in totals due to rounding.
