VANCOUVER, BC / ACCESSWIRE / June 3, 2020 / Orsu Metals Corporation (TSXV:OSU) ('Orsu' or the 'Company') is pleased to report assay results of the reverse circulation ('RC') drilling program as part of its ongoing preparation for pilot mining. The most significant intercepts at each of the main mineralized domains at Sergeevskoe project assayed:

1. Kozie - drillhole RCS02 intercepted 2.53 grams per ton gold ('g/t Au') Au over 9 meters ('m'), including 4.85 g/t Au over 4 m;
2. Klyuchi West - drillhole RCS04 intercepted 1.49 g/t Au over 85 m, including 2.96 g/t Au over 24 m;
3. Central domain of Zone 23 - drillhole RCS10 intercepted 1.7 g/t Au over 21 m, including 2.81 g/t Au over 10 m, and drillhole RCS09 intercepted 5.22 g/t Au over 6 m, including 9.47 g/t Au over 3 m;
4. Adit 5 - drillhole RCS14 intercepted 4.22 g/t Au over 11 m, including 8.09 g/t Au over 5 m and 1.69 g/t Au over 10 m, including 2.28 g/t Au over 6 m; and
5. Peak Klyuchi - drillhole RCS01 intercepted 4.28 g/t Au over 3 m.

Alexander Yakubchuk, the Company's Director of Exploration, commented: 'All RC holes were drilled in between the previous drill fences or in between the diamond drill holes within the previous drill fences. The overall average grade of the mineralized intercepts appears to be remarkably similar with the resource model, further confirming its validity.'

Dr. Sergey V Kurzin, the Executive Chairman commented: 'The RC drilling program was conducted by the pilot mining contractor and independently confirmed the geological model of the Sergeevskoe property. The RC drilling was an essential part of the preparation to commence pilot mining in the second half of this summer. Now we and our pilot mining contractor are conducting a grade control drilling program specifically delineating mineralization to be bulk mined within two planned initial open pits at the property. Orsu Metals will be reporting the results of the grade control drilling when available. Our knowledge and confidence of the deposit grows daily.'

The Company completed 1721 meters in an RC drilling program of 18 drill holes. At least one hole was drilled into each mineralized domain of Sergeevskoe (see Figure 1). The depth of drilling varied from 23 to 115 m, with holes drilled in different directions at 60 degrees dip. All holes should be considered as infill drillholes as they were drilled in between the existing holes. The main purpose of the RC drilling was to test the continuity of gold grade in the updated resource model as part of the preparation for the pilot mining program (see press release May 27, 2020).

Gray lines are traces of trenches and drillholes drilled by Orsu in 2017-1019.

Although individual intercepts varied both in greater and smaller mineralized width and gold grade in comparison with the expected width and grade of the resource model, there was not a single case of an unconfirmed mineralized interval. Moreover, several new mineralized bodies were identified in the RC holes drilled within the fences. They could not be previously modelled due to less than 2 m width identified in 2017 to 2019 in the diamond core drill holes. The new RC holes showed that such small intercepts of the mineralized bodies appear to significantly change their width upwards, sometimes exceeding 10 m (Table 1).

Table 1 below shows all mineralized intercepts that exceed 2 m in downhole width grading more than 0.5 g/t Au.

Klyuchi West - drillhole RCS04 (see Table 1) intercepted 1.49 g/t Au over 85 m from 15 m depth to the end of the hole. This wide intercept includes four mineralized intervals grading:

• 1.19 g/t Au over 22 m from 15 m depth (compared to 0.8 g/t Au over 22 m in the resource model);
• 0.92 g/t Au over 11 m from 38 m depth (compared to 0.8 g/t Au over 6 m in the resource model);
• 0.85 g/t Au over 11 m from 54 m depth (compared to 0.8 g/t Au over 23 m in the resource model); and
• 2.96 g/t Au over 24 m from 76 m depth (compared to 1.0 g/t Au over 10 m in the resource model).

Kozie - a comparison of RC and previous diamond drilling results indicates some grade and width increase to the west. Hole RCS02 (see Table 1), drilled in the west of the domain, intercepted:

• 0.51 g/t Au over 4 m from 3 m depth (compared to 0.6 g/t Au over 5 m in the resource model);
• 2.53 g/t Au over 9 m from 46 m depth, including 4.85 g/t Au over 4 m (compared to 3.2 g/t Au over 3 m in the resource model);
• 1.1 g/t Au over 5 m from 61 m depth (new body); and
• 1.76 g/t Au over 5 m from 68 m depth (compared to 2.7 g/t Au over 15 m in the resource model).

Peak Klyuchi - which was previously drill tested only to a limited extent, RCS01 intercepted (see Table 1) 4.28 g/t Au over 3 m and 0.72 g/t Au over 2 m.

Adit 5 - four drillholes confirmed the continuity of gold mineralization intercepting four to six mineralized intervals, some of which were new bodies (see Table 1). Drillhole RCS14 intercepted:

• 4.22 g/t Au over 11 m, including 8.09 g/t Au over 5 m, from 23 m depth (compared to 1.8 g/t Au over 11 m in the resource model);
• 1.69 g/t Au over 10 m, including 2.28 g/t Au over 6 m, from 36 m depth (compared to 1.4 g/t Au over 10 m in the resource model);
• 0.88 g/t Au over 6 m from 61 m depth (compared to1.3 g/t Au over 6 m in the resource model); and
• 0.58 g/t Au over 2 m from 96 m depth (compared to 4.1 g/t Au over 2 m in the resource model).

Similarly, all mineralized intervals were confirmed by RC drilling in Zone 23 West, Central and East domains.

Central domain - drillhole RCS10 intercepted:

• 1.0 g/t Au over 9 m 46 m depth (compared to 1.3 g/t Au over 9 m in the resource model);
• 0.62 g/t Au over 3 m from 58 m depth (New body);
• 1.7 g/t Au over 21 m, including 2.81 g/t Au over 10 m, from 63 m depth (compared to 1.0 g/t Au over 5 m in the resource model); and
• 0.83 g/t Au over 6 m from 90 m depth (compared to 1.3 g/t Au over 3 m in the resource model).

Similarly, drillhole RCS09 (see Table 1), among other intervals, intercepted 5.22 g/t Au over 6 m, including 9.47 g/t Au over 3 m, from 90 m depth (compared to 1.1 g/t Au over 10 m in the resource model).

The individual holes in each domain revealed much wider or more narrow intercepts than predicted from the resource model. The overall results clearly indicate an upside potential of the Sergeevskoe mineralization when the Company performs more infill drilling in the future.

The overall weighted average grade of the new intercepts is 1.45 g/t Au, which correlates to the average grade of 1.45 g/t Au in the resource model. This generally confirms the robustness of the resource model.

The reported intercepts correspond to the downhole width. True thickness is estimated to constitute from 65 to 80% of the reported intervals.

All reported RC drilling was performed by an independent contractor under supervision of Orsu. Irrespective of lithologies, exact 1 m intervals were sampled consistently in all drillholes. There are no unsampled intervals.

Fire assay analysis was performed at the certified analytical laboratory of the Alexandrovskoe gold mine, located 6 km to the west from the mineralized domains of the Sergeevskoe project. The laboratory is owned by Zapadnaya Gold Mining Company (http://www.zapadnaya.com/qa/alexandrovka.html), which is independent from Orsu. The detection limit of the laboratory is 0.1 g/t Au, with assay precision to 0.01 g/t Au. The laboratory included blank samples in the batches of 30 to 40 samples. The laboratory run random duplicate analytical tests of assayed material, averaging 20 samples.

In March 2020, the World Health Organization declared COVID-19 a global pandemic. This contagious disease outbreak, which has continued to spread, has adversely affected workforces, economies, and financial markets globally. It is not possible for the Company to predict the duration or magnitude of the adverse impacts of the outbreak and its effects on the Company's business or ability to raise funds. The COVID-19 pandemic has not affected the progress of the ongoing exploration campaign on the Sergeevskoe Project as the Company is able to conduct its ongoing exploration in this remote area of Russia.
