CEO's Comments
Rubicon President and Chief Executive Officer George Ogilvie, P.Eng., stated, "Our infill drilling program continues to yield positive results, which gives us great confidence that our Measured and Indicated Mineral Resource estimate will continue to expand at depth. We are targeting up to 7,500 m of infill drilling during the first half of 2020, which will focus on the approximately 190,000 ounces in the current Inferred Mineral Resource estimate between the 976 and 1,098 m Levels. We believe there is a good probability of converting some of these estimated ounces to the Measured and Indicated categories and then subsequently being added to the planned Feasibility Study mine plan."
"With the Phoenix Gold Project advancing on a positive path, we are commencing exploration with orientated core drilling on the highly-prospective McFinley and Pen Zone targets that are located 500 m from the Project mill and existing underground infrastructure, including the mine shaft with a fully functional hoisting system. These targets have historical drilling that yielded high-grade results that we intend to follow up on. Our intention over the course of this year will be to update the historical Mineral Resource estimate at McFinley to an NI 43-101 compliant Mineral Resource estimate."
2020 Plan
Rubicon's 2020 Plan is comprised of value-creating initiatives that the Company believes advances and enhances the Phoenix Gold Project. Below is a summary of the 2020 Plan:
Feasibility Study scheduled for H2/2020
Based on the 2020 Mineral Resource Estimate1 of 811,000 ounces of gold in the Measured and Indicated Mineral Resource categories, the Company believes that the Project has a sufficiently well-defined Mineral Resource estimate on which to commence mine planning and additional engineering work to determine the Project's commercial viability. Rubicon has accordingly initiated a Feasibility Study on the Project, with its completion anticipated in H2/2020. The Company had already commenced feasibility work on upgrading its surface infrastructure in the fourth quarter of 2019.
Lower Level Infill Drilling to Convert Inferred Mineral Resource estimates to the Measured and Indicated Mineral Resource Categories
Between the 976 and 1,098 m Levels, the Company estimates approximately 190,000 ounces of Inferred Mineral Resources1. The Company intends to infill drill this area with the goal of upgrading the ounces to at least the Indicated Mineral Resource category. If successful, Rubicon could potentially include a portion 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 current Measured and Indicated Mineral Resource estimates.
The recently completed structural review study and associated dataset confirms previously identified orientation distributions for the various recognized families of structural features including faults, foliations, and vein sets to depth. Orientation measurements for two types of structural features were identified as most useful for modelling the structural controls on mineralization. The orientation distribution of the faults are very similar to that of the mineralized veins. The updated structural model and data analysis will be used to optimize and de-risk future drilling programs and Mineral Resource modelling.
Exploring McFinley and Close Proximity Targets
Rubicon will commence more than 5,000 m of underground orientated diamond drilling to determine the Mineral Resource potential of the historic McFinley Zone2 ("McFinley") (approximately 500 m northwest of the F2 Gold Zone) and the Pen Zone3 (approximately 500 m northwest of the Project's F2 Gold Zone). The drilling will follow-up on the historic high-grade drill intercepts that were intersected in these two targets. Rubicon intends to deliver Mineral Resource estimates for both McFinley and the Pen Zone in 2020 and 2021, respectively. Due to the proximity of the 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.
Between 1982-1989, exploration work was conducted at McFinley, including 200,000 feet (or 60,960 m) of diamond drilling, underground development and culminated with a bulk sampling program2. Based on the data collected from the exploration work, a historical Mineral Resource estimate was developed for McFinley which outlined 334,007 tons (or 303,000 tonnes) at 0.20 gold ounces per ton (or 6.86 g/t Au) in the Inferred Mineral Resource category, to a depth of 400 feet (or approximately 122 m below surface)2.
In the Pen Zone, historic drilling was conducted between 2003-2005, which yielded significant gold intersections including 1.34 oz/ton gold (or 45.94 g/t Au) over 3.28 feet (or 1.0 m), 0.71 oz/ton gold (or 24.34 g/t Au) over 1.48 feet (or 0.45 m) and 0.51 oz/ton gold (or 17.48 g/t Au) over 1.64 feet3 (or 0.50 m)3.

Cautionary Note to U.S. Readers Regarding Estimates of Measured, Indicated and Inferred Mineral Resources
This news release uses the terms "Measured" and "Indicated" Mineral Resource and "Inferred" Mineral Resource. The Company advises U.S. investors that while these terms are recognized and required by the Canadian Securities Administrators, they are not recognized by the United States Securities and Exchange Commission (SEC). The estimation of "Measured" and "Indicated" 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 an "Inferred", "Measured", or "Indicated" Mineral Resource estimate will ever be upgraded to a higher category.
Under Canadian rules, 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 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. U.S. investors are cautioned not to assume that any part or all of an "Inferred", "Measured" or "Indicated" Mineral Resource exists or is economically or legally mineable. Information concerning descriptions of mineralization and Mineral Resource contained herein may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
