‍Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) is pleased to report additional assay results from the ongoing surface sampling program at the Company’s Cerro Caliche gold project in Sonora State, Mexico. 275 new samples were assayed, bringing the total for the current sampling program to 1,567 samples over four mineralized corridors as described in the Company’s news release dated July 20, 2021.

The new results further confirmed material extensions of up to 750 meters over two southern linear structural corridors at the Buena Suerte and El Colorado zones. The sampling results also revealed oxide gold mineralized “windows” among the two southern structural corridors. The windows were accessed via recently built road cuts and drill site excavations and future sampling will investigate potential continuation and extensions.

Surface rock samples were collected from several well-defined vein and gold mineralized structures by channel sampling perpendicular across measured veins and wall rocks with sample lengths ranging from 0.4 to 2.0 meters. Assay results from 17 samples returned grades between 2.5 and 14.3 grams of gold per tonne (“g/t Au”). The image below illustrates five high-priority window targets for the upcoming drilling program as each demonstrated strong stockwork quartz veining and outlined broad zones of gold and silver mineralization.

Analysis of approximately 284 surface samples collected during the current program from the El Colorado/La Ventana and Buena Suerte/San Quintin corridors confirm the southern extensions of the vein trends with numerous parallel sheeted veins and quartz veinlet stockwork. All samples were given equal weighting.

Sample highlights from the El Colorado/La Ventana Corridor:

• Window A, approximately 100 meters by 130 meters along strike, with 39 samples averaging36 g/t Au and 0.6 grams of silver (“g/t Ag”), including one sample grading 8.6 g/t Au.
• Window B, approximately 300 meters by 280 meters along strike, with 39 samples averaging 0.63 g/t Au and 4.8 g/t Ag, including one sample grading 4.9 g/t Au over 1 meter and another sample grading 3.7 g/t Au over 1.2 meters.
• Window C, approximately 300 meters by 50 meters oriented northeast perpendicular to the northwest-oriented regional vein trends, with 51 samples averaging 0.76 g/t Au and 1.9 g/t Ag.

Sample highlights from the Buena Suerte/San Quintin Corridor:

• Window D, a teardrop shaped area at the Buena Suerte vein zone extension, covering 350 meters in length by a width ranging from 40-80 meters, with 61 samples averaging 0.65 g/t Au and 18.5 g/t Ag.
• Window E, approximately 220 meters by 100 meters along strike, with 94 samples averaging 0.28 g/t Au and 1.3 g/t Ag, including one sample grading 2.7 g/t Au.

Outside of the targeted windows, sample assays from a vein considered to be the Hanging Wall of the Cabeza Blanca vein (located between windows B and D), returned 1.2 meters averaging 10.8 g/t Au. This vein is hosted in the rhyolitic intrusive rock and is mostly soil covered. Almost one kilometer to the east of window D, sample assays from a one-meter vein located near the Cuervos vein returned 7.5 g/t Au.

Rock types hosting veining in the southern corridor are mainly a rhyolite sub-volcanic unit and a meta quartzite-shale unit with lesser biotite granodiorite.  Alteration is predominantly silicification associated with quartz veinlets and sericite with gold-silver mineralization cutting these rock types.

The remaining samples were collected from more widespread areas to the northeast and east of the southern extensions (outside of the above map area). Samples results from this region are generally encouraging and the eastern La Española corridor is another priority target for the Company. Mapping and sampling are currently underway at La Española to quantify the size of the exposed vein. Four prior drill holes intersected the vein including previously announced scout hole SCR-068 which was drilled in 2019 and which intercepted 6.179 g/t AuEq over 3.05 meters and 1.327 g/t AuEq over 9.14 meters.

Stockpiled vein material at the La Española mine surface is noteworthy for its distinct multiple bands with greenish quartz, while dikes of rhyolitic composition are common within the ridge that hosts the vein, which cuts both the rhyolitic unit and quartzite.

Mel Herdrick, Sonoro’s VP of Exploration noted, “With this latest round of mapping-sampling information, new priority drill targets have been identified, increasing management’s confidence the next drilling campaign may extend gold mineralization to the south.”

Kenneth MacLeod, Sonoro’s President and CEO added, With the continuing success of the surface sampling program in areas that had not been previously explored, we are confident that mineralization at Cerro Caliche will continue to expand with the reverse circulation drill program scheduled to restart in the fall.”

John Darch Sonoro’s Chairman commented, “These newly identified oxide gold mineralized windows are essential to our fall drilling campaign to expand mineralization at Cerro Caliche. The presence of strong stockwork quartz veining and broad zones of gold and silver mineralization in all five windows confirm that these will be our high-priority targets. We are particularly encouraged with the number of high-grade samples results as we continue to investigate the potential for near-surface higher-grade mineralization. Confirmation of high-grade mineralization could potentially improve the economics of our proposed open-pit Heap Leach Mining Operation in the initial years of mining.”

As previously announced, drilling activities on the concession have been paused since April 2021 to provide the exploration team sufficient time to ensure all data and assistance was available for the completion of a Preliminary Economic Assessment (PEA) anticipated to be completed in the Fall. The Company has engaged Micon International Ltd. to prepare an updated resource estimation for inclusion in the PEA being prepared by D.E.N.M. Engineering Ltd.
