Vancouver, BC, May 21, 2019 – Silver One Resources Inc. (TSXV: SVE; OTC Pink: SLVRF; FSE: BRK1 – “Silver One” or the “Company”) is pleased to provide an update of its metallurgical testing on the historic leach pads at its Candelaria project in Nevada. New results show that up to 75% of the total silver contained in composite samples from the old leach-pads (an increase of more than 47%-79% over historic production recoveries) can potentially be recovered by reprocessing the heaps using very fine grinding in combination with microbubble technology. This testing was done at First Majestic Silver Corp.’s La Parrilla Mine laboratory in Durango, Mexico. Metallurgical work continues with ongoing efforts being focused on evaluating the economics of recovering gold and silver by either high-pressure grinding roll (“HPGR”) or by very fine milling combined with microbubble technology.

During the 18th week of the year (April 29th to May 5th, 2019), at least 35 press releases were announced by companies working in Mexico. ON MEXICO ISSUES, Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas, due to an illegal blockade lasting for more than a month now. More than 300 mine employees protested outside the Zacatecas Congress, accusing José Narro, senator by Morena (the president’s party) of instigating the blockade. Drill core from La Xora project in Nayarit was added to The Mexican Core Shack. ON EXPLORATION, Nine companies presented advances in the exploration of their properties: In Baja, One World Lithium has received the permits to drill its Salar Del Diablo property. In Sonora, Sonoro Metals disclosed assays for the first 15 RC holes of the second drilling campaign; Ridgestone updated the work done to date at Rebeico; Minaurum staked a large chunk of ground at its Alamos project. In Chihuahua, Silver Spruce released surface sample results from its Pino de Plata project; Radius Gold released exciting results from the first hole of the second drilling campaign at Amalia; Kootenay Silver has initiated drill road construction for its incoming campaign at Columba. In Jalisco, GoGold released results from its drilling campaign at Los Ricos. In Zacatecas, Alien Gold updated on the exploration effort at its Donovan 2 property.

ON RESOURCES AND DEVELOPMENT, no relevant news. ON DEALS AND CORPORATE ISSUES, Alio Gold received notice of a civil claim from a former Rye Patch shareholder.
ON MEXICO ISSUES
- Newmont Goldcorp Corp. informed on the intention to temporarily suspend operations at the Peñasquito mine in Zacatecas (one of the largest in Mexico, produced 272 K Oz Au in 2018), due to an illegal blockade by a trucking contractor and some members of the Cedros community that began on March 27, 2019. The company announced on April 9 that the trucking contracts will now be signed with independent truckers, to their economic benefit and to avoid the repeated extortion blockades by the current trucking contractor. Newmont Goldcorp denounced that the blockader’s public claims that focus in water quality and employment, turn in a direct petition for large amounts of money when done privately. The company asks for help from the Mexican and Zacatecan authorities to resolve the illegal blockade that affects the income of more than 20 thousand persons, directly or indirectly. On a different event, about 300 employees of Minera Peñasquito, protested outside the Zacatecas Congress against the illegal blockade that keeps paralyzed the Peñasquito mine. The protesters accused Jose Narro, senator by the president party, Morena, and his acolyte Felipe Pinedo of blackmailing the company with false water contamination statements.
- Core from La Xora project, in Nayarit, was added to the Mexican Core Shack (https://gambusinoprospector.com/mexican-core-shack/), under the epithermal low sulphidation section.
- Sonoro Metals Corp. reported assay results from the first 15 reverse circulation holes of the second phase drilling program at its Cerro Caliche property in Sonora. All holes encountered gold mineralization, which extend mineralization 1.25 Km NW from the Central Zone, where the first drill campaign defined a series of NW striking structures, outlining three shallow bulk tonnage oxidized mineralized zones in metasedimentary and volcanic rocks. Previously reported results come from the Central Zone prospects Japoneses, Abejas, El Colorado and Guadalupe, whereas the new drill holes tested El Rincon, Gloria, El Boludito, and Veta de Oro zones. Highlighted results comprise 10.67 m @ 2.73 gpt AuEq; 3.05 m @ 5.48 gpt AuEq; 10.67 m @ 0.74 gpt AuEq; 6.1 m @ 0.80 gpt AuEq; 15.24 m @ 1.05 gpt AuEq.
- Alien Metals Ltd. updated on its exploration work at its Donovan 2 project in Zacatecas. Work to date supports indications of volcanogenic massive sulphide (VMS) mineralisation on multiple target areas open along strike, with surface assays of up to 3.3% Cu, 0.25% Zn. Currently there are magnetic, chargeabilty and resistivity anomalies, and a gravity survey underway is to refine the targets on this project, which is 24 kilometers from Teck’s San Nicolas deposit.
- Ridgestone Mining Inc. announced that exploration work to date on its Rebeico property in Sonora defined the 1.2 km long Alaska vein and intensely altered breccia zones SW of the vein, carrying Cu, Au and Ag values, as well as bismuth anomalies. An 18 line-kilometer induced polarization (IP) survey identified a chargeability anomaly below the breccia zone. A 12 hole 1,430 m diamond drill program tested 500 m of the Alaska vein. Eight of the twelve holes intersected significant grades, including: 0.80 m @ 1.41% Cu, 2.95 gpt Au; 2.0 m @ 2.78% Cu, 8.69 gpt Au; 1.40 m @ 3.25 gpt Au; 1.50 m @ 1.39 gpt Au; 1.0 m @ 0.30% Cu, 5.61 gpt Au; 3.25 m @ 2.41% Cu, 8.31 gpt Au; 1.50 m @ 1.22% Cu, 36.10 gpt Au.
- One World Lithium Inc. has received the permit required to start its 12 hole, 4,250 m drilling program at its Salar del Diablo property in Baja California. The company intends to test three geophysical anomalies, a geochemical anomaly, and structures that may trap and concentrate brines. The Salar del Diablo Property has never been drilled in the past.

The two targets in the area comprise El Terrero and the Gossan area. At El Terrero, a 32 hectares zone “of multiple flat-lying brecciated zones hosted by a zone of strong argillic alteration” is the target, while at the Gossan area a series of hornfels and skarns developed near an intrusive contact may host massive sulphide replacement bodies associated to structures.
- Radius Gold Inc. reported the first results from the second diamond drill campaign at its Amalia project in Chihuahua. The program is operated by Radius and funded by Pan American Silver Corp. under a JV agreement by Which Pan American can earn an initial 65% by making cash payments totaling US$1.5 M (of which US$100 K have been paid) and spending US$2 M on exploration over four years. The first hole in this campaign intersected 44 m @ 12.38 gpt Au, 309 gpt Ag, including 11 m @ 39.9 gpt Au, 323 gpt Ag. The estimated true width of the zone is 34 m, consisting of “an epithermal breccia and quartz sulphide stockwork vein zone ” located on or near to the contact between overlying Tertiary rhyolitic ignimbrite and the footwall andesite volcaniclastics of the Late Cretaceous Tarahumara Formation. Diorite dykes appear to be emplaced along the fault zone and are associated with mineralization”.
- Minaurum Gold Inc. staked an additional 20,872 hectares on its Alamos project in Sonora. Additionally, mapping has revealed four new vein zones: Rosario, La Dura Oeste, La Dura and La Tijera. These four zones bring the total of veins zones of the district to twenty. The Rosario vein has been traced for 500 m, with samples assaying 304 gpt Ag and 227 gpt Ag over 1 m and 675 gpt Ag, 1.0% Cu, 0.9% Pb over 2 m.

VANCOUVER, BC – April 18, 2019 – SilverCrest Metals Inc. (“SilverCrest” or the “Company”) is pleased to announce positive metallurgical test results for the Las Chispas Property (the “Property”) located in Sonora, Mexico. Previous metallurgical testing of Las Chispas mineralization suggested precious metal recoveries for three separate composites of two veins using standard bottle roll leach tests showing 98.9% for gold (“Au”) and 86.6% for silver (“Ag”). These new detailed metallurgical test results show estimated recoveries for gold ranging from 98.4% to 98.9% and for silver ranging from 91.4% to 94.8%, or recovery for silver equivalent (“AgEq”; based on 75 (Ag): 1 (Au), defined in table below) from 94.0% to 96.5%, confirming high gold recoveries and improved silver recoveries. These test results were based on a process flowsheet, using conventional methods comprised of gravity concentration and intensive leaching followed by gravity tails standard leaching. The upcoming Preliminary Economic Assessment (“PEA”) will use AgEq recoveries approximately 4% lower than the average of three master composites until further detail test-work is completed in 2019.
