As part of the Company\u2019s strategy to fast-track the development of a Heap Leach Mining Operation (HLMO) at Cerro Caliche, over 5,500 kilograms of mineralized material from ten 85-mm diameter PQ core holes are being shipped to the laboratory for metallurgical testing. With continuing success from the ongoing drilling program, Sonoro\u2019s management has expanded its development plans from the previously announced pilot level project to assess the economic viability of a proposed 8,000 ton per day mining operation.<\/p>\n<p align=\"justify\">The metallurgical testing program is focused on determining the heap leach characteristics of the oxide mineralization at Cerro Caliche and will provide quantified estimates of gold and silver recovery from the various mineralized zones near surface and at depth, in addition to providing recommendations for crushing sizes and associated process flow sheet development. The testing will incorporate the following components:<\/p>\n<ul type=\"disc\">\n<li style=\"margin-bottom:8pt\">Heap leach testing, including variability composite testing, drill core composite testing, bottle roll testing and column leach testing.<\/li>\n<li style=\"margin-bottom:8pt\">Materials characterization testing, including comminution testing, mineralogy, load\/ permeability testing, crushing work index, abrasiveness index and ore density.<\/li>\n<\/ul>\n<p align=\"justify\">Preliminary column leach testing of at-surface mineralized material sampled from the Japoneses Zone was carried out at a dedicated facility near Cerro Caliche by Sonoro during 2019. These tests demonstrated the material to be amendable to cyanide leaching, which will now be confirmed by an independent laboratory.<\/p>\n<p align=\"justify\">The current testing program will take into consideration the gold mineralization\u2019s characteristics which are divided into two distinct metallurgical domains, as follows:<\/p>\n<ul type=\"disc\">\n<li style=\"margin-bottom:8pt;text-align:justify\">Hydrothermal vein quartz structures of variable thickness, from 0.10 to 5 meters, and with variable textures from massive quartz with some vuggy quartz zones to gray quartz. The vein structures are mostly related to fault zones with resulting breccias and silicified zones in the hosting rocks.<\/li>\n<li style=\"margin-bottom:8pt;text-align:justify\">Veinlets-stockwork mineralization, with relatively lower average gold grades. These are zones with erratic and irregular quartz narrow veinlets from 0.01 to 0.20 meters width, sometimes with breccia and shatter textures. These veins, veinlets and stockwork are usually in silicified and oxidized zones in the hosting rock and frequently associated with similarly altered rhyolite dikes.<\/li>\n<\/ul>\n<p align=\"justify\">Drilling at Cerro Caliche has shown that the mineralization throughout the various zones is oxidized to the full extent of all the drill holes. Observation of the drill cuttings suggests that the near-surface oxidized mineralization characteristics are similar to the deeper oxidized mineralization.<\/p>\n<p align=\"justify\">The current exploration work is part of the Company\u2019s targeted fast-track development schedule for the Cerro Caliche project with the aspirational goal of commencing gold production by the end of 2021. However, a successful realization of that goal remains subject to several material conditions, most notably including the satisfactory completion of metallurgical testing, securing required environmental permitting, a favourable preliminary economic assessment and the availability of project financing.<\/p>\n<p align=\"justify\">Jorge Diaz, Sonoro\u2019s Vice President Operations, stated, <em>\u201cIt is worth noting that current exploration results are confirming Sonoro\u2019s expectations regarding Cerro Caliche\u2019s potential to become another important <\/em><em>heap leach<\/em><em> min<\/em><em>ing operation<\/em><em> in Sonora State.\u201d<\/em><\/p>\n<p align=\"justify\">Kenneth MacLeod, Sonoro\u2019s CEO, added, <em>\u201cLaunching the metallurgical testing program represents <\/em><em>an important<\/em><em> advancement in the development of Cerro Caliche<\/em><em>. <\/em><em> We are also pleased to have engaged the services of McClelland Laboratories, a widely respected metallurgical testing firm with significant expertise in the successful planning of similar open-pit <\/em><em>heap<\/em><em>leach <\/em><em>mining operations in Sonora State.<\/em>\u201d<\/p>\n<p align=\"justify\">John Darch, Sonoro\u2019s Chairman added, <em>\u201cThe engagement of <\/em><em>McClelland Laboratories to independently conduct metall<\/em><em>u<\/em><em>rgical <\/em><em>testing at Cerro Caliche is a cle<\/em><em>ar and decisive <\/em><em>milestone on Sonoro\u2019s fast-track development schedule <\/em><em>for<\/em><em> commenc<\/em><em>ing<\/em><em> gold production by the end of 2021.\u201d<\/em><\/p>\n<p align=\"justify\">\n        <strong>Geologic Description<\/strong><br \/>\n        <br \/>Cerro Caliche is located 45 kilometers east southeast of Magdalena de Kino in the Cucurpe-Sonora Mega-district of Sonora, Mexico.\u00a0 Multiple historic small underground mines were developed in the concession including Cabeza Blanca, Los Cuervos, Japoneses, Las Abejas, Boluditos, El Colorado, Veta de Oro and Espanola.\u00a0 Mineralization types of the Cucurpe-Sonora Mega-district includes epithermal low sulfidation veins and related mineralized rhyolitic dikes and associated volcanic domes.\u00a0\u00a0<\/p>\n<p align=\"justify\">Host rocks include Jurassic-Cretaceous meta-sedimentary rock units including argillite, shale, quartzite, limestone, quartz pebble conglomerate and andesite.\u00a0 Tertiary age medium coarse-grained granodiorite-granite is present in the westerly parts of the concessions near the historic Cabeza Blanca Mine.\u00a0 It is apparent that veining cuts pervasively alters the intrusive stock. Younger rhyolite occurs in irregular bodies distributed in higher elevations in the northerly part of the concession, including the Rincon area, where it occurs as flows, sills, dikes and rhyolite domes.\u00a0 Part of the rhyolite is mineralized and appears to have a connection with deposition of epithermal gold mineralization throughout the property.<\/p>\n<p align=\"justify\">\n        <strong>Qualified Person Statement<\/strong><br \/>\n        <br \/>Stephen Kenwood, P.Geo., a Director of Sonoro, is a Qualified Person within the context of National Instrument 43-101 (NI 43-101) and has read and approved this news release.\u00a0 Readers are cautioned that the presence of mineralization on historic mines adjacent to or on Cerro Caliche is not necessarily indicative of gold mineralization in the concessions held by the Company.<\/p>\n<p align=\"justify\">\n        <strong>About McClelland Laboratories<\/strong><br \/>\n        <br \/>McClelland Laboratories, Inc.
