Venadas II Discovery hole P32: 1.2m grading 279 g/t (8.1 opt) Silver; 0.7 g/t GoldVANCOUVER, British Columbia, March 03, 2020 (GLOBE NEWSWIRE) — MAG Silver Corp. (MAG: TSX / NYSE A) (“MAG”) announces results from the 2019 28-hole (33,864 metre (“m”)) diamond drilling program on the Juanicipio Joint Venture Property (Fresnillo plc 56% / MAG 44%). The program expanded and upgraded the wide, high-grade Deep Zone and confirmed additional northeast-trending veins (See Press Release dated March 4, 2019). Continued in-fill and exploration drilling on other targets is ongoing in 2020, with four surface rigs running concurrently with mine development and construction (see Joint Venture Press Release dated February 24, 2020).Drill Highlights (see Table 1):Confirms and expands continuous wide, high-grade mineralization in the Valdecañas Deep ZoneConfirms and expands the wide, high-grade zones in the Anticipada VeinConfirms and expands the Venadas Vein to the south with strong silver and gold gradesDiscovery of northeast-trending Valentina and Venadas II veins through drilling and development.Exceptional intercepts include:

Additional proximal veins to Valdecañas include the parallel Juanicipio vein located 1,000m to the south and 3 newly discovered northeast-trending veins (Venadas, Venadas II and Valentina) all of which intersect the Valdecañas Vein. Remodeling now shows Valdecañas as a single vein with deep dilatant zones (bulges) on each side, and also significantly extends the Anticipada Vein to the east.Drilling in 2019 returned the thickest and deepest lateral intercepts to date on the Valdecañas Vein, with deep mineralization now continuous over a 2,000m strike length and up to 1,100m vertically from the top of the Bonanza Zone. The 2019 vein intercepts range in width from approximately 1 m to over 21m (See Figure 2 and tables at https://magsilver.com/site/assets/files/5810/nr-mar3-2020-table1-sdadds.pdf) and the Valdecañas Vein remains open laterally to the claim boundaries at both ends and to depth. The best 2019 intercept is Hole D5-12, which cut 5.7m (true width) grading 3,884 g/t (113 ounces per ton (“opt”)) silver, 8.4 g/t (0.25 opt) gold, 6.5% lead, 9.7% zinc and 0.3% copper. This includes a 0.8m (true width) zone that ran 16,271 g/t (475 opt) silver, 9.2 g/t gold (0.27 opt), 17.8% lead, 11.8% zinc and 0.2% copper. The location of this intercept is important as it greatly expands the thick and high-grade eastern dilatant zone. Other significant holes include D1-5 and D1-10, both within the western dilatant zone, and D6-6 in the eastern dilatant zone. D5-11 also adds very good width and grade above the east dilatant zone.The Anticipada Vein is sub-parallel to and lies 50-100m in the hangingwall of the Valdecanas Vein. In 2019 it was coincidentally cut by 11 holes targeting the Valdecañas Vein and several of these intercepts significantly expand the vein. This is especially the case in a vertical zone along its western reaches where it widens and higher grades appear (See Figure 3 and tables at https://magsilver.com/site/assets/files/5810/nr-mar3-2020-table1-sdadds.pdf). The best intercept is in Hole D6-6, which cut 21.2m (true width) grading 147 g/t (4.3 opt) silver, 1.2 g/t gold, 3.9% lead, 8.8% zinc and 0.3% copper. This includes a 1m (true width) zone that ran 548 g/t (16 opt) silver, 2.1 g/t gold, 17.4% lead, 14.2% zinc and 0.9% copper. Two other holes (D5-10 and D5-11) extend the well-mineralized zone on the eastern end of the vein. The remaining six holes tested the western limits of the vein and show moderate to relatively weak mineralization. The Anticipada Vein remains open to depth and to the east.The Pre-Anticipada Vein is also subparallel to the Valdecañas Vein and is located a further 50-100m into hangingwall above the Anticipada Vein. It was coincidentally cut by five infill holes targeting the Valdecañas Vein but their geometry was not favourable (See Figure 4 and tables at https://magsilver.com/site/assets/files/5810/nr-mar3-2020-table1-sdadds.pdf). The two easternmost holes (D5-8 and D5-9) cut appreciable silver and gold values within the coherent high-grade zone that characterizes the Pre-Anticipada Vein (See Figure 4) but do not significantly expand it. Pre-Anticipada remains open for 200-300m to the eastern property boundary and to depth.Five surface drill holes tested the Venadas Vein (See Figure 5 and tables at https://magsilver.com/site/assets/files/5810/nr-mar3-2020-table1-sdadds.pdf), the first northeasterly-trending vein ever found in the Fresnillo District (See Press Release March 4, 2019), to depth and to the south. The hole drilled farthest to the south (93P) extends the vein to 800m from its intersection with the Valdecañas Vein and cut high silver and gold grades with no base metals (2.5m (true width) grading 918 g/t (27 opt) Ag and 1.8 g/t Au). Vein textures and the lack of base metals indicates this is a high-level intercept and that the vein should have good potential to depth. Hole 97P was the only hole drilled below 93P and it hit only a narrow, pinched-down vein. Additional deeper holes are planned for 2020 to determine where the vein opens up again at depth.Importantly, two additional northeast-trending veins (Venadas II and Valentina; See Figures 6 and 7 and tables at https://magsilver.com/site/assets/files/5810/nr-mar3-2020-table1-sdadds.pdf) were discovered during 2019 through a combination of drilling and being cut in development headings. Both had been suspected based on oblique angle vein intercepts in several holes directed towards the Valdecañas Vein (See Press Release of March 4, 2019). Drill hole P32, which was designed to intercept Venadas II on the way to Valdecañas, cut 1.2m (true width) grading 279 g/t (8 opt) Ag; 0.7 g/t Au. The Valentina Vein was also cut multiple times by the eastern development ramp and a number of historic Valdecañas vein drill holes, the best of which is Hole M39 which cut 0.7m grading 1,215 g/t (35 opt) Ag, and 3.6 g/t Au.The intercepts for Venadas, Venadas II and Valentina lack significant base metal grades (with the exception of one intercept) indicating that these holes have likely cut the veins high in the mineralizing system. Also, all three veins have been intercepted on both the hangingwall and footwall side of the Valdecañas Vein in drill core and underground workings. This, combined with underground exposures of mineralized cross cutting northeast trending veinlets, strongly suggest that these veins cross-cut the main-stage of the Valdecañas Vein and may coincide with the long-recognized late gold-rich mineralization stage. Short-hole underground drilling and drifting is contemplated for fleshing out these veins and determining what relationship they have with the Valdecañas Vein.Qualified Person: Dr. Peter Megaw, Ph.D., C.P.G., and Lyle Hansen, M.Sc., P.Geo have acted as the qualified persons as defined in National Instrument 43-101 for this disclosure and supervised the preparation of the technical information in this release.
