Moneta Porcupine Mines : Intercepts 1.93 m @ 34.36 g/t Gold, 3.00 m @ 5.38 g/t Gold, and 3.00 m @ 5.73 g/t Gold At South West

Toronto, Ontario -- June 21, 2018 - Moneta Porcupine Mines Inc. (TSX:ME) (OTC:MPUCF) (XETRA:MOP) ('Moneta' or the 'Company') is pleased to announce the results from seven additional diamond drill holes completed on the South West Deposit ('South West') located within the Company's Golden Highway Project (located 110 km east of Timmins, Ontario, see Figure 1).

Highlights:

Step-out drilling at South West has continued to extend the strike and depth extent of the vein structures and extend the size of the mineralized shoots. One new vein, Walnut has been confirmed by drilling, increasing the total number of veins to seventeen.

Vein array

• SW-1: Drill hole MGH17-084 intersected 15.00 m @ 1.76 g/t Au including 2.10 m @ 3.02 g/t Au confirming the shallow extensions of this shoot by 25 m to the south

The latest assay results are from seven drill holes totalling 4,813.6 m of drilling at South West that continues to test the higher grade structural targets. The ongoing drill program at South West follows up on the previously announced exploration drill program undertaken by the Company in late 2017 and early 2018 on the Golden Highway Project and that was expanded to 41,100 m in 70 drill holes. Assays for additional drill holes are pending and will be released as they become available for the South West and '55' areas.

South West Deposit

Drilling to date at South West has been successful in confirming the existence of seventeen (17) stacked veins and eight (8) mineralized shoots. The veins trend NW as stacked veins, steeply dipping to the SW at 70°, and occur south of the Banded Iron Formation ('BIF') within clastic Timiskaming age sediments. A new vein, Walnut, the seventeenth identified to date was confirmed in the current drilling. The first six modelled veins have an average width of approximately 2.90 m and are spaced 25 m to 30 m apart. The vein structures can be traced now for over 400 m strike length and have been historically drilled to depths of up to 1,200 m and remain open but appear to narrow to the south.

The sheared contact with the BIF hosts mineralized stockwork zones ('shoots') which plunge ~65° to ~75° to the west and occur up to 50 m long, 25 m wide and have been confirmed to depths of over 800 m. A total of eight shoots have now been identified.

The veins and stock-work style veining within the shoots occur as quartz-carbonate-pyrite veins within an ankerite alteration halo occasionally associated with sericite. A zone of pyrite-chlorite and quartz veinlets occur within the vein corridors and also host mineralization. The veins can be brecciated and occur as quartz matrix supported breccia zones. The eight (8) mineralized shoots and seventeen (17) vein corridors have now been successfully traced across a width of 1,200 m.

South West Drill Results

Drill hole MGH17-081 was drilled to test the up-dip and northern extensions of the six initial modelled veins. The drill hole intersected the Tamarack (2.60 m @ 2.06 g/t Au), Elm (1.00 m @ 5.15 g/t Au), Birch (3.00 m @ 5.38 g/t Au, including 1.00 m @ 8.28 g/t Au), Balsam (1.00 m @ 3.50 g/t Au), Cedar (1.93 m @ 34.36 g/t Au including 1.03 m @ 65.10 g/t Au), and Pine (1.08 m @ 5.18 g/t Au). The drill hole added up to 50 m to the vein extensions.

Drill hole MGH17-082 was drilled to test the Walnut, Willow and Arbutus veins to the south and intersected the Willow vein at 465.40 m depth assaying 0.30 m @ 2.21 g/t Au extending the vein by 50 m. The drill hole did also confirm the Redwood and Alder vein structures. The drill hole was drilled to the south of the SW-3 mineralized shoots and confirmed that the mineralization is not continuous along the BIF contact.

Drill hole MGH17-083 was also drilled to test the BIF contact south of SW-3 and the Maple, Oak, Alder vein structures at depth as well as the new Walnut vein, located ~50 m west of Willow. The drill hole intersected Maple at 444.67 m (1.80 m @ 1.53 g/t Au) and the Walnut vein structure at 697.50 m assaying 3.00 m @ 5.73 g/t Au including 0.75 m @ 9.17 g/t Au extending this vein by 50 m to the south and 100 m depth. The BIF contact south of SW-3 was confirmed not to host mineralization.

Drill hole MGH18-084 was drilled to test the west veins and the southern and depth extensions of the main veins by 100 m as well as the southern extensions of the SW-1 shoot near the Main Fault. The drill hole intersected the West veins (1.10 m @ 2.58 g/t Au) and a 25 m southern step out of the SW-1 shoot (15.00 m @ 1.76 g/t Au at 447.50 m depth). The holes also confirmed up to 100 m extensions of the Tamarack (0.61 m @ 3.28 g/t Au), Cedar (1.00 m @ 5.89 g/t Au), Pine (0.65 m @ 8.37 g/t Au) and the Spruce vein structure (2.50 m @ 3.62 g/t Au including 1.00 m @ 6.59 g/t Au).

Diamond drill holes MGH18-085 and MGH18-086 were drilled to test additional 100 m extensions of the main veins to the south and confirmed the extensions of the Tamarack (2.90 m @ 2.60 g/t Au) and Spruce vein structures (0.80 m @ 3.96 g/t Au). The veins structures were intersected to the south but appear to narrow.

Drill hole MGH17-087 was drilled to confirm the main veins and test the depth and southern extensions of the Maple, Oak and Alder veins. The drill holes confirmed the main Elm (2.00m @ 2.79 g/t Au), Birch, Balsam (1.25 m @ 5.27 g/t Au), Pine (0.50 m @ 10.75 g/t Au) and Spruce (1.20 m @ 8.72 g/t Au) vein structures. MGH18-087 confirmed the Maple (0.45 m @ 10.65 g/t Au), Oak (0.70 m @ 3.81 g/t Au) and the Alder (2.00 m @ 2.00 g/t Au at 575.00 m) vein structures at depth and with up to 50 m step outs to the south.

All core drilling conducted by Moneta is oriented. Drill core is sawn and half is sent ALS Canada Inc. for drying and crushing to -2 mm, with a 1.00 kg split pulverized to -75 µm (200#). A 50 g charge is Fire Assayed and analyzed using a AAS finish for Gold. Samples above 10.00 g/t Au are analyzed by Fire Assay with a gravimetric finish and selected samples with visible gold or high-grade mineralization are assayed by Metallic Screen Fire Assay on a 1.00 kg sample. Moneta inserts independent certified reference material and blanks with the samples and assays routine pulp repeats and coarse reject sample duplicates with the samples, as well as completing third-party check assays at Activation Laboratories Ltd.
