Corporate Updates

SONORO CLOSES CERRO CALICHE EXPANSION AGREEMENT

VANCOUVER, Canada, March 20, 2018, Sonoro Metals Co rp., (“Sonoro”) (TSXV: SMO) (OTCQB: SMOFF),

announces that its Mexican subsidiary, Minera Mar D e Plata, SA de C.V. has executed a formal option ag reement

(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 (“Ro sario”) on the terms initially disclosed in a news release dated

March 5, 2018. Rosario is located contiguous to the recently-acquired Cerro Caliche concessions in the prolific

Cucurpe Sonora Mega-district of Sonora, Mexico. The option agreement increases the land holdings under option to

Sonoro in this important gold mining district to 1,455 hectares.

The Rosario Option Agreement provides for Sonoro to acquire a 100% interest in Rosario for total consi deration to

the Vendor of US$1,600,000, payable in escalating c ash installments over 72 months. The initial first- year

installment of US$60,000 was paid 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 has be en granted an option to purchase the NSR at any tim e for

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

The Rosario and Cerro Caliche concessions (collectively “Cerro Caliche”) 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 defi ning a resource with significant gold mineralizatio n. A historic

non-published report completed by Corex (Flores, 2008) includes a non NI 43-101 resource estimation.

“Our Hermosillo-based exploration team, headed by n oted geologist Mel Herdrick, has commenced a surfac e

sampling program to define additional zones for a d rilling program scheduled to begin during the secon d half of

2018,” said Kenneth MacLeod, President and CEO of Sonoro. “Our aim is to verify the earlier data and expand the

scope and scale of the gold resource indicated in the Corex report.”

The Cucurpe Sonora Mega-district includes Premier Gold’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.

takes responsibility for this news release. Readers are cautioned that the presence of mineralization on properties

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