SONORO GOLD ANNOUNCES INITIAL 10,000 METERS DRILLING RESULTS FROM ONGOING CAMPAIGN AT CERRO CALICHE

Sonoro Gold Corp. (SGO) has released assay results from the first 10,000 meters of a planned 50,000-meter reverse-circulation drilling campaign at its Cerro Caliche project in Sonora, Mexico. The company completed 46 RC holes in the central-western region, targeting the Buena Suerte, El Quince, Cabeza Blanca, Guadalupe, El Colorado, and San Quintin areas.

The company reports that El Quince represents a new potentially significant zone, while mineralization at Buena Suerte extends into areas previously modeled as waste. Additionally, continuity observed at Cabeza Blanca, Guadalupe, and El Colorado may connect proposed pits for a preliminary economic assessment.

Headline intervals from the campaign include: - SCR-340: 18.29 m @ 3.392 g/t Au and 44.3 g/t Ag, including 9.14 m @ 6.438 g/t Au and 85.8 g/t Ag - SCR-348: 9.14 m @ 3.076 g/t Au and 26.1 g/t Ag, including 6.09 m @ 4.531 g/t Au - SCR-349: 18.29 m @ 1.674 g/t Au and 30.4 g/t Ag, including 6.10 m @ 4.568 g/t Au - SCR-347: 13.71 m @ 0.704 g/t Au, including 1.53 m @ 4.439 g/t Au - SCR-356: 15.24 m @ 0.648 g/t Au, including 3.04 m @ 1.299 g/t Au - SCR-363: 10.66 m @ 0.935 g/t Au, including 4.57 m @ 1.6 g/t Au

The reporting cutoff for these results is 0.13 g/t Au, with estimated true thickness calculated at 60–90% of the drilled length.

Sonoro Gold Corp. (SGO) released drill results from a near-development explorer/developer, distinct from an earnings release. The company previously reported no revenue and a working-capital deficiency in Q1 2026, but subsequently completed multiple private placements.

The company’s market capitalization stands at approximately CAD 86 million, based on a recent share price of CAD 0.20. This valuation contrasts with a Preliminary Economic Assessment (PEA) showing an after-tax NPV8 of USD 224 million at USD 3,500/oz gold. The market is not pricing in the full PEA value, reflecting risks related to execution, dilution, permitting, and financing.

The stock has round-tripped from a high near CAD 0.32-0.34 in late 2025/early 2026 to CAD 0.20 at the end of August 2026.

The results confirm continuity, add a new zone, and demonstrate mineralization in areas previously modelled as waste. However, the findings are not transformational. The best gram-metre result falls below Sonoro's own historical anchors, no interval reaches the excellent band, and no resource update is yet provided.

For the infill and resource-definition component, intercepts at or above the 0.37 g/t resource grade are confirmatory. For the El Quince step-out, the drilling represents encouraging first-pass results but has not yet proved a new deposit.

Sonoro Gold Corp. is a Canadian-listed gold exploration and development company operating the Cerro Caliche and San Marcial projects in Sonora, Mexico. The Cerro Caliche property is a low-sulphidation epithermal oxide gold-silver system currently being advanced toward an open-pit heap-leach operation.

Updated preliminary economic assessment (PEA) economics, based on gold at USD 3,500/oz and silver at USD 48/oz, project an after-tax NPV8 of USD 224 million and an after-tax internal rate of return (IRR) of 50%. The project features a 10-year mine life with a throughput of 16,000 tonnes per day, producing an average of 46,000 ounces of gold equivalent (AuEq) per year. Initial capital expenditure is estimated at USD 83 million, with all-in sustaining costs (AISC) of USD 1,902/oz AuEq. Gold recovery is projected at 72%, while silver recovery stands at 27%.

The company’s land package has expanded substantially through a series of acquisitions, growing from roughly 1,350 hectares to more than 8,600 hectares. The capital structure remains heavily diluted, with approximately 432 million shares outstanding and about 646 million fully diluted shares, including numerous warrants and options.
