Sonoro Expands Cerro Caliche Property IN Mexico

Mergers & Acquisitions

SONORO EXPANDS CERRO CALICHE PROPERTY IN MEXICO

VANCOUVER, Canada, March 5, 2018, Sonoro Metals Corp., (“Sonoro”) (TSXV: SMO) (OTCQB: SMOFF),

announces that its Mexican subsidiary, Minera Mar De Plata, SA de C.V. has executed a Letter of Intent to enter into

an option agreement (the “Rosario Option Agreement”) with a resident of Tucson, Arizona (the “Vendor”), to acquire

a 100% interest in the 403.5 hectare Rosario group of concessions (“Rosario”) located contiguous to the recently -

acquired Cerro Caliche concessions in the prolific Cucurpe Sonora Mega -district of Sonora, Mexico, thereby

increasing Sonoro’s land holdings in this important gold mining district to 1,455 hectares.

The Cucurpe Sonora Mega -district includes Premier Go ld’s Mercedes gold mine; Goldgroup Mining’s Cerro Prieto

gold mine; Agnico Eagle’s recently purchased Santa Gertrudis gold mine; and other gold mineralized prospect areas.

The Rosario and Cerro Caliche concessions were the subject of earlier drill programs by Cambior Gold and Corex

Gold Corp., with the most recent drilling occurring in 2008. Total drilling by those two companies in the last 20 years

of 10,118 meters in 101 drill holes reportedly outlined large areas of mineralized material that may in future programs

assist in defining a resource with significant gold mineralization. A historic non-published report completed by Corex

(Flores, 2008) includes a non NI 43-101 resource estimation.

The Rosario Option Agreement will provide for Sonoro to acquire a 100% interest in Rosario for total consideration

to the Vendor of US$1,600,000, payable in escalating cash installments over 72 months, with the initial first -year

installment of US$60,000 payable on execution of the Rosario Option Agreement.

Following exercise of the Option, the Vendor will hold a 2% net smelter returns royalty (“NSR”) from the proceeds

of the sale of minerals from Rosario. Sonoro will be granted an option to purchase the NSR at any time for

US$1,000,000 for each one percent of the 2 percent NSR.

"The addition of Rosario to our Cerro Caliche concessions mostly completes the acquisition program for the area of

mineralization outlined and partially explored by Corex Gold during thei r drilling in 2008,” said Kenneth MacLeod,

President and CEO of Sonoro. “Our technical team, headed by noted geologist Mel Herdrick, is now focusing on

expanding the Corex resource and exp loring the many other structural zones with gold mineralization demonstrated

throughout much of the concession area.”

About Cerro Caliche and the Cucurpe Sonora Mega-District:

The Cerro Caliche concessions are located about 45 km southeast of Magdelena de Kino in north-central Sonora State

with good road access. Older local historic mines including Los Cuervos, Japoneses, Las Abejas, Boluditos which

operated during periods up to about 130 years ago are included in or are near the concessions.

Mineralization types of the Cucurpe Mega-district include variants of epithermal low sulfidation, epithermal

mineralized dikes and associated volcanic rocks, and sub -adjacent mesothermal Carlin type gold mineralization.

These deposits in the district appear to be genetically linked with a similar mineralization age ranging from 40 to 30

Ma. Altered felsic dikes cut ting the mineralized meta -sedimentary rock units are associated with mineralization in

both rock units. The Cerro Caliche area is a sub-district of the Cucurpe Mega-district with many gambusino workings

and exploration pits in the concession area as well as drill holes. Immediate plans are to utilize new and prior data

available from surface sampling and east -west soil sampling lines focusing in the areas with prospect pits to identify

targets for additional work including necessary permitting and completing a reverse circulation drilling program after

mid-year. The form of mineralization includes veins, parallel sheeted veinlets to stockwork veinlet zones, and

disseminated-fracture controlled gold without quartz veinlets are present in the concession area containing gold .

The Cucurpe mega-district has historically been regarded as a higher-grade vein-only dominated district including the

Cerro Prieto and the Mercedes mines. Activities at Cerro Prieto and Santa Gertrudis mine areas have developed open

pit resources in more recent years with more disseminated to stockwork style gold mineralization. Sonoro’s San

Marcial project is located about 30 kilometers further west of Cerro Caliche with gold mineralization hosted in Jurassic

shale and quartzite meta-sedimentary units.

adjacent to or in proximity to Cerro Caliche is not necessarily indicative of mineralization on Cerro Caliche.
