There is no certainty that Measured and Indicated mineral resource estimates will be converted to the Proven and Probable mineral reserve categories and there is no certainty that the Updated 2020 Mineral Resource Estimate will be realized. There is no guarantee that Inferred mineral resource estimates can be converted to Indicated or Measured mineral resource categories, or that Indicated or Measured mineral resource estimates will be converted to mineral reserves. Mineral resource estimates that are not mineral reserves do not have demonstrated economic viability. The Updated 2020 Mineral Resource Estimate may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant risks, uncertainties and other factors, as more particularly described in the Cautionary Statements at the end of this news release.
Mining cash cost components include in-stope mining costs, underground utilities, material handling, and development costs.

For further details refer to the mineral resource estimate for the Project effective as of December 6, 2020 (the "January 2020 Estimate") reported in the Company's NI 43-101 technical report for the Project dated January 3, 2020 (the "January 2020 Technical Report"), which is available on SEDAR www.sedar.com and on the Company's website at www.battlenorthgold.com. The January 2020 Estimate is not current and should not be relied upon.
General observations and commentary on the Updated 2020 Mineral Resource Estimate1
Battle North President and Chief Executive Officer George Ogilvie, P.Eng., stated, "The expansion of the Measured and Indicated mineral resource estimate to 979,000 ounces gives us confidence that we can potentially extend the current conceptual mine life to the Bateman Gold Project5 within our impending Feasibility Study. The weighted average drill density within the Updated 2020 Measured and Indicated mineral resource estimate categories is 17 m drill centre spacing, providing us with a great degree of confidence in the data that drives the estimates. We are particularly pleased with two key aspects of the exploration program. The first was the high conversion rate of the January 2020 Inferred mineral resource estimate ounces into the Indicated category, which exceeded 90%. The second was the addition of approximately 132,000 higher-grade ounces in the Updated 2020 Indicated mineral resource estimate grading 8.15 g/t Au between the 976 m and 1,098 m Levels. These results provide strong indications of the further potential exploration upside of the F2 Gold Zone at the Bateman Gold Project."
We have made good progress with the mine planning, engineering work, capital cost request for proposals ("RFP") and believe we are more than 75% complete with the feasibility work programs. We remain on track to deliver the Feasibility Study in the second half of 2020."
The potential quantity and grade of "Explore Target" areas are conceptual in nature. There has been insufficient exploration of the "Explore Target" areas to define a mineral resource estimate and it is uncertain if further exploration will result in the "Explore Target" being delineated as a mineral resource estimate.
Updated 2020 Mineral Resource Estimate1 Details
The Updated 2020 Mineral Resource Estimate (see Table 1 above) benefits from 570,861 m of core drilling in 1,683 drill holes. The F2 Gold Zone at the Bateman Gold Project covers a strike length of approximately 1,200 m and depths down to 1,403 m Level and remains open along strike and at depth. The Updated 2020 Mineral Resource Estimate excludes the crown pillar and depletion from prior test trial mining.
The Updated 2020 Mineral Resource Estimate was evaluated using the same geostatistical block modelling approach as with the January 2020 Estimate4. The block model was classified in accordance with Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") Definition Standards for Mineral Resources and Mineral Reserves (May 2014). Average drill spacing for the Updated 2020 Measured, Indicated and Inferred mineral resource estimates were 8 m, 19 m, and 28 m, respectively.
The sensitivity of the Updated 2020 Mineral Resource Estimate to the selection of cut-off grade is summarized as grade/tonnage data in Table 3 below. Please refer to Table 4 at the end of the news release for further details on the geological modelling and high-grade treatment strategies, including top-cut values and coefficients of variation ("CV") for each sample population. The Updated 2020 Mineral Resource Estimate by underground level is tabulated in Table 5 (at the end of this news release). Please see Diagrams 1, 2, and 3 (at the end of this news release) showing the conceptual plan and longitudinal views of Zones 1 and 2 (the two main mineral domains) of the Updated 2020 Mineral Resource Estimate blocks in the Measured, Indicated, and Inferred mineral resource categories and Explore Target6 areas.

Geological Model and Structural Geology
The geological interpretation of the new drilling utilized in the Updated 2020 Mineral Resource Estimate was reviewed and there were no material changes noted. The geological and structural model, as developed in 2018 and updated in early 20205, continues to be observed at depth throughout the F2 Gold Zone.
Based on the Updated 2020 Mineral Resource Estimate of 979,000 ounces of gold in the Measured and Indicated categories at a 3.0 g/t Au cut-off, the Company believes that the Project has a sufficiently well-defined mineral resource base on which to continue mine planning and additional engineering work to determine the Project's commercial viability. The Feasibility Study on the Project remains on track for completion in H2/2020, with the following updates:

Table 4: Further Details on Geological Modelling and High-Grade Treatment Strategy
Geological domains were modelled based on broad low-grade mineralization envelopes associated with the three main high-titanium basalt lenses defined on the Project property (from mine grid West-to-East including Hanging Wall Basalt, West Limb Basalt, and F2 Basalt). TMAC used block model techniques to estimate gold grade into 2 m x 2 m x 2 m blocks using Geovia GEMS software. All as logged rock types were grouped into three main stratigraphic units consisting of ultramafic units (UM), high-titanium basalt units (HTB) and felsic intrusive units (FI) as determined by grade distribution analysis of the rock types present. These stratigraphic units were then used as mineralization domains to constrain the gold grade estimates. The HTB was treated as a hard boundary with the other lithologies. Grade estimation was completed using inverse distance weighting cubed (ID3) interpolation using 1.0 m composite samples, with additional search controls based on variography and trends of mineralization. A 4-pass search strategy was used where gold estimates required a minimum of 5 and maximum of 11 samples for the first 2 passes, a minimum of 4 and maximum of 8 samples for the 3rd and a minimum of 3 and maximum of 8 samples for the 4th pass. The majority of blocks (>99%) were estimated using two drill holes. Search distances were factored for each successive search. Average density values were assigned to the model based on lithology.
High-Grade Treatment Strategy
High-grade composite samples (outliers) were controlled during the estimation process using a combination of distance restriction and capping (composites capped to a defined maximum value). Within the first pass, samples were capped and limited to the first pass search range. For Passes 2 to 4, the outlier samples were removed from the grade estimation. Capping values were assessed based on cumulative probability, disintegration analysis and decile analysis for each lithology within mineral envelopes for Zones 1 to 4 as summarized below. CV of uncapped and capped composite grades for Zones 1 to 4 are summarized below.

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, as well as those described in the Q1, 2020 MD&A and accompanying financial statements, the 2020 AIF and the January 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 resource estimates 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) results of geological and structural modeling including stope design; (vi) proposed mining operations, including dilution; (vii) the evaluation of mine plans subsequent to the date of any estimates; and (viii) the possible failure to receive required permits, licenses and other approvals. The mineral resources estimates referenced in this news 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 Canadian Securities Administrators ("NI 43-101").
Cautionary Statement to U.S. Readers
Information concerning descriptions of mineralization and mineral resources estimates contained in this news release 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 NI 43-101. The definitions used in NI 43–101 differ from the definitions under applicable United States securities laws. For example, this news 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 Canadian Securities Administrators, 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 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.
