Companies Mentioned: DSVMF
Discovery Metals Corp. (TSX-V: DSV, OTCQX: DSVMF) ("Discovery" or the "Company") is pleased to announce results from eight diamond drill holes completed at its flagship Cordero project ("Cordero" or "the Project") located in Chihuahua State, Mexico. The holes are part of a Phase 1 diamond core drilling program that commenced in September 2019. The Phase 1 drill program was recently expanded from 35,000-metres ("m") to 55,000 m and has the goal of defining a large-scale, high-margin project with excellent leverage to rising silver prices.
Highlight intercepts include:
Todos Santos Vein
-- 1.4 m averaging 1,907 grams per tonne silver equivalent ("g/t AgEq") in hole C20-342 from 147.0 m (700 g/t Ag, 0.74 g/t gold ("Au"), 16.1% lead ("Pb") and 14.0% zinc ("Zn")) within a 5.3 m breccia interval that averaged 653 g/t AgEq (225 g/t Ag, 0.27 g/t Au, 5.1% Pb, 5.5% Zn)
Parcionera Vein
-- 1.5 m averaging 1,119 g/t AgEq in hole C20-338 from 149.8 m (489 g/t Ag, 0.82 g/t Au, 2.9% Pb and 11.1% Zn) within a 4.3 m vein that averaged 651 g/t AgEq (365 g/t Ag, 0.55 g/t Au, 2.1% Pb, 4.0% Zn)
North-East Extension
-- 120.4 m averaging 114 g/t AgEq in hole C20-333 from 206.8 m (30 g/t Ag, 0.11 g/t Au, 0.4% lead Pb and 1.5% Zn)
-- 134.6 m averaging 92 g/t AgEqin hole C20-336 from 194.6 m (23 g/t Ag, 0.05 g/t Au, 0.5% Pb and 1.1% Zn)
South Corridor
-- 44.8 m averaging 139 g/t AgEqin hole C20-337 from 173.9 m (35 g/t Ag, 0.10 g/t Au, 0.7% Pb and 1.7% Zn)
-- 0.8 m averaging 3,214 g/t AgEqin hole C20-337 from 291.3 m (1,992 g/t Ag, 0.79 g/t Au, 16.1% Pb and 14.2% Zn)
Taj Singh, President and CEO, states: "We continue to intercept wide zones of bulk-tonnage style mineralization along the North-East Extension at Cordero. In addition, our understanding of the previously overlooked high-grade vein trends on the property continues to evolve. Four of the eight drill holes in this news release hit high-grade feeder structures, including 1,907 g/t AgEq over 1.4 m in our first ever drill hole targeting the Todos Santos vein trend, and 1,119 g/t AgEq over 1.5 m at the Parcionera vein trend. These two vein trends have a current combined strike length of over 1.5 kilometres based on historical underground workings. With a second drill rig now operational, we look forward to testing both the strike length and depth continuity of these and other extensive feeder structures alongside our bulk-tonnage breccia-hosted targets."
DRILL RESULTS:
Todos Santos Vein: Hole C20-342 was drilled under a historic mine working on the north-east extent of the Todos Santos vein trend and intercepted a high-grade sulphide vein approximately 140 m below surface that returned 1.4 m averaging 1,907 g/t AgEq (700 g/t Ag, 0.74 g/t Au, 16.1% Pb and 14.0% Zn). Vein mineralization is semi-massive pyrite (20%), galena (15%) and sphalerite (15%). The Todos Santos vein trend is currently interpreted to be 1.2 kilometres ("km") long, has a south-west strike and dips steeply to the north-west, based on the alignment of six historic workings and eight pierce points from historic drill holes.
Parcionera Vein: The current 350 m strike and 255 m proven depth extent of this vein trend is defined by two of the larger historical mine workings as well as pierce points from six historical drill holes. Hole C20-338, drilled under the NE trend of the historical workings, intercepted 4.3 m of high-grade vein material from 149.8 m averaging 651 g/t AgEq(365 g/t Ag, 0.55 g/t Au, 2.1% Pb, and 4.0% Zn) including 1.5m of 1,119 g/t AgEq (489 g/t Ag, 0.82 g/t Au, 2.9% Pb, and 11.1% Zn). Vein mineralization is dominantly coarse-grained pyrite (40%) in bands 20-50cm wide with intercalations and 2-3cm bands or veinlets of red-brown sphalerite (4-5%) and coarse-grained galena (2-3%).
North-East Extension: Five of the eight holes in this current release were drilled to the north-east of the core Pozo de Plata zone in areas where there were significant gaps in previous drilling. Four of these drill holes intercepted multiple broad zones of stockwork and/or breccia-hosted mineralization including hole C20-333, drilled 650 m north-east of Pozo de Plata, which intercepted 120.4 m averaging 114 g/t AgEq (30 g/t Ag, 0.11 g/t Au, 0.3% Pb and 1.5% Zn) of stockwork mineralization in calcareous siltstone and mudstone. Hole C20-336, drilled 700 m north-east of Pozo de Plata intercepted 134.6 m averaging 92 g/t AgEq (23 g/t Ag, 0.05 g/t Au, 0.5% Pb and 1.1% Zn) of stockwork mineralization hosted in dacite and dacite breccia.
South Corridor: Hole C20-337, drilled along the South Corridor, intercepted 44.8 m averaging 139 g/t AgEq (35 g/t Ag, 0.10 g/t Au, 0.7% Pb and 1.7% Zn) and 23.6 m averaging 186 g/t AgEq (82 g/t Ag, 0.09 g/t Au, 0.8% Pb and 1.7% Zn). These stockwork mineralized intervals are hosted in calcareous siltstone and mudstone. The deeper interval also encountered a previously unidentified feeder vein that returned 0.8 m averaging 3,214 g/t AgEq (1,992 g/t Ag, 0.79 g/t Au, 16.1% Pb and 14.2% Zn). The South Corridor, which is separated from the core Pozo de Plata zone by the main Cordero fault, has seen significantly less drilling in comparison to the North Corridor and will be a key area of focus for drilling over the remainder of the Phase 1 drill program.
Drill hole locations for all holes are shown in Figure 1 (see links below). Further drill highlights are provided in the table below.

PHASE 1 DRILL PROGRAM UPDATE:
The Company recently expanded its Phase 1 drill program by 20,000 m to 50,000-55,000 m. 19,440 m (49 holes) from this program have been completed to date. Assays from five holes are pending. The Company added a second drill rig during the first week of July. Further drill rigs will be added when the Company is confident health and safety risks related to COVID-19 can be managed effectively.
Drilling will be focused on two key areas: 1) Targeting of broad zones of breccia-hosted mineralization in the east and north-east of both mineralized corridors and 2) Testing of the width, grade and continuity of extensive high-grade vein systems identified in and adjacent to historical artisanal underground workings during the early history of the Project.

About the Cordero Project
Cordero is located on the eastern edge of the Sierra Madre Occidental mountains in the northern part of the Central Mexican Silver Belt, Mexico's premier porphyry and carbonate replacement deposit district. Mineralization at Cordero is similar in nature to well-known nearby bulk tonnage precious metals mines and projects (e.g. Newmont Corporation's Penasquito Mine and Orla Mining Ltd.'s Camino Rojo project). In addition to the bulk tonnage mineralization there are also multiple high-grade silver-zinc-lead-gold sulphide vein trends as evidenced by more than 40 historical shallow, vertical shafts and associated underground workings.
