TSX: RMX | OTCQX: RBYCF

TORONTO, May 7, 2020 /CNW/ - Rubicon Minerals Corporation (TSX: RMX | OTCQX: RBYCF) ("Rubicon" or the "Company") announces that it has filed its interim Financial Statements and Management's Discussion and Analysis ("MD&A") for the quarter ended March 31, 2020. The Company confirms that copies of these filings can be obtained at www.rubiconminerals.com or www.sedar.com

Financial Highlights from the quarter ended March 31, 2020

• Cash position: As of March 31, 2020, the Company had cash and cash equivalents and short-term investments of approximately $15.8 million.
  
  On February 27, 2020, the Company closed a public flow-through share offering of 6,294,000 common shares on a "flow-through" basis under the Income Tax Act (Canada) at a price of $1.43 per flow-through share for aggregate gross proceeds of approximately $9.0 million (the "Offering"). The proceeds from the Offering will be used to incur Canadian exploration expenses (within the meaning of the Income Tax Act (Canada), "CEE") related to Rubicon's Phoenix Gold Project, McFinley Zone, Pen Zone, and other regional exploration targets in Ontario. The Company will renounce such CEE to the purchasers of the flow-through common shares under the Offering with an effective date of no later than December 31, 2020.
  
  
• Exploration and evaluation expenditures: For the quarter ended March 31, 2020, the Company spent approximately $3.2 million in expenditures related to drilling, maintenance and technical consulting fees, including work on the Feasibility Study for the Project. Expenditures were lower by $0.3 million compared to the same period in 2019 as the Company did not incur expenditures on underground development as part of its 2020 drilling campaign focused on infill and exploratory drilling and potential updates to the 2020 Mineral Resource Estimate to support the ongoing feasibility study work.
  
  
• General and administrative expenses (including salaries and benefits, and consulting and professional fees): The Company spent approximately $0.9 million on expenditures related to general and administrative, salaries and benefits, and consulting and professional fees in Q1/2020, marginally lower than expenditures in Q1/2019.

Outlook

As of May 7, 2020, the Company had cash and cash equivalents of approximately $14.3 million. The Company has sufficient financial resources to carry out the Company's planned activities:

• Additional safety measures in response to COVID-19: as of March 12, 2020, the Company had implemented additional precautionary measures aimed at enhancing the health and safety for its employees (see the Company's March 23, 2020 news release for further details). In March 2020 and updated April 3, 2020, all non-essential businesses were ordered to close their physical workplaces by the Government of Ontario. To-date mining is considered an essential business under guidelines of the Government of Ontario and the Company continues to operate. At the present time, Rubicon's exploration activities and feasibility study work have not been impacted. It is not possible to reliably estimate the financial impact of the length or severity of COVID-19.
  
  
• Feasibility Study remains on track for H2/2020 completion: The Company commenced feasibility work on the Project in the fourth quarter of 2019. Rubicon estimates that it has completed approximately 59% of the feasibility study. Much of the stope design and mine planning has substantially progressed. Request for proposals ("RFP") for various surface and underground work and equipment, including tailings management facility upgrades, have either been sent out to vendors or received and are under review. An RFP related to the underground development is currently being finalized. Ammonia treatment plant designs are currently being evaluated.
  
  
• Lower Level Infill Drilling to Upgrade Inferred Mineral Resource estimates to the Measured and Indicated Mineral Resource Categories: The 2020 Mineral Resource Estimate between the 976- and 1,098-m Levels, includes approximately 190,000 ounces of estimated Inferred Mineral Resources. The Company intends to infill drill this area with the goal of upgrading those Inferred Mineral Resource estimates to at least the Indicated Mineral Resource category. If successful, Rubicon could potentially include any of such potentially upgraded Mineral Resource estimates in the mine plan to be contemplated by the anticipated feasibility study. The Company plans to drill up to 7,500 m of orientated diamond drilling with the goal of expanding the Measured and Indicated Mineral Resource estimates. Assay results are pending for infill drilling incurred to-date.
  
  
• Exploring McFinley and Close Proximity Targets: Rubicon plans to complete more than 5,000 m of underground diamond drilling to determine the Mineral Resource potential of the historic McFinley Zone ("McFinley") (approximately 420 m west of the F2 Gold Zone) and the Pen Zone (approximately 500 m northwest of the F2 Gold Zone). The drilling will follow-up on the historic high-grade drill intercepts that were intersected in these two targets. Rubicon expects to deliver Mineral Resource estimates for both McFinley and the Pen Zone in 2020 and 2021, respectively. Due to the proximity of these targets to the existing underground and surface infrastructure of the Phoenix Gold Project, mineralized material at McFinley and the Pen Zone areas have the potential to augment the conceptual production profile of the Phoenix Gold Project. The Company has completed back sampling of target areas at McFinley (results pending) and has commenced drilling. Rubicon has completed 1 of 4 holes planned for the Pen Zone, with assay results pending.

Cautionary Statement Regarding Mineral Resources
Until mineral deposits are actually mined and processed, Mineral Resources must be considered as estimates only. Mineral Resource estimates that are not Mineral Reserves do not have demonstrated economic viability. The estimation of Mineral Resources is inherently uncertain, involves subjective judgement about many relevant factors and may be materially affected by, among other things, environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant risks, uncertainties, contingencies and other factors described in the foregoing Cautionary Statements, in the Q1, 2020 MD&A and accompanying financial statements as well as in the 2020 AIF and the 2020 Technical Report. The quantity and grade of reported "Inferred" Mineral Resource estimates are uncertain in nature and there has been insufficient exploration to define "Inferred" Mineral Resource estimates as an "Indicated" or "Measured" Mineral Resource and it is uncertain if further exploration will result in upgrading (or converting) "Inferred" Mineral Resources to an "Indicated" or "Measured" Mineral Resource category. The accuracy of any such estimates is a function of the quantity and quality of available data, and of the assumptions made and judgments used in engineering and geological interpretation, 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 mineral prices; (ii) results of drilling and development; (iii) results of test stoping and other testing; (iv) metallurgical testing and other studies; (v) proposed mining operations, including dilution; (vi) the evaluation of mine plans subsequent to the date of any estimates; and (vii) the possible failure to receive required permits, licenses and other approvals. The Mineral Resources estimates referenced in this press release were reported using Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves in accordance with National Instrument 43-101 of the CSA ("NI 43-101").

Cautionary Statement to U.S. Readers
Information concerning descriptions of mineralization and "Mineral Resources" contained in this AIF may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission ("SEC") under applicable United States securities laws. Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 ("NI 43-101") of the Canadian Securities Administrators (the "CSA"). The definitions used in NI 43 101 differ from the definitions under applicable United States securities laws. For example, this this press release uses the terms "Measured" and "Indicated" Mineral Resources and "Inferred" Mineral Resources which, while defined by NI 43-101 and recognized and required by the CSA, they are not recognized by the SEC. The estimation of "Measured", "Indicated" and "Inferred" Mineral Resources involves greater uncertainty as to their existence and economic feasibility than the estimation of a "Reserve". The estimation of "Inferred" Mineral Resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of Mineral Resources. It cannot be assumed that all or any part of a "Measured", "Indicated" or "Inferred" Mineral Resource estimate will ever be upgraded (or converted) to a higher category.

It should not be assumed that any part or all of a "Measured", "Indicated" or "Inferred" Mineral Resource estimate exists or is economically or legally mineable. Under Canadian securities laws, estimates of "Inferred Mineral Resources" may not form the basis of feasibility studies, pre-feasibility studies or other economic studies, except in prescribed cases, such as in a preliminary economic assessment (or PEA) under certain circumstances. The SEC normally only permits issuers to report mineralization that does not constitute "Reserves" as in-place tonnage and grade without reference to unit measures. Under U.S. standards, mineralization may not be classified as a "Reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the "Reserve" determination is made.

Qualified Persons
