Minera Alamos Intersects 127m of 0.81 g/t Gold Ending in Mineralization from Phase 1 Drilling at Santana Project, Sonora, Mexico

Toronto, Ontario and Vancouver, British Columbia--(Newsfile Corp. - November 1, 2018) - Minera Alamos Inc. (TSXV: MAI) (the "Company" or "Minera Alamos") is pleased to report additional results from its Phase 1 drill program at the Santana gold project, Sonora, Mexico.

Phase 1 Exploration Highlights:

Latest Hole S18-123 - 127 m of 0.81 g/t Au - Along with S18-123/124, holes S18-116/117/118/119 (previously reported) delineated broad zones of near surface mineralized extensions of the Nicho Main deposit trending southwest of previous historical drilling. Other highlights included 93.5 m of 0.63 g/t Au (S18-116) and 80.4 m of 1.05 g/t Au (S18-117).

Holes S18-123/124 which tested the SW limits of the Nicho Main zone both ended within the mineralized horizon (approximately 150m down hole at 45-degree dip) and indicate potential for deep mineralization extensions that were not considered in previous exploration programs.

New Discovery Hole S18-121 - 96 m of 1.47 g/t AuEq - First hole drilled into a new zone of gold/silver/copper mineralization (Divisadero Zone) located approximately 200m north of the previously known limits at the Nicho Main/Norte Zones. Subsequent surface mapping has confirmed that the new area appears to be open for expansion in all directions.

Discovery of New Nicho-Style Gold Structure (Zata Zone) - Over a surface area of approximately 400m x 400m, sixty- six (66) rock samples were assayed with 50% exhibiting grades suitable for heap leaching (>0.10 g/t Au).

"The Phase 1 program at the Santana gold project has been an overwhelming success," states Darren Koningen, CEO of Minera Alamos. "With the first significant exploration activity on the project since 2011 we have been able to demonstrate that the Nicho Main zone remains open for further expansion. In addition, our ongoing efforts to better understand the geological controls on gold mineralization that occur throughout the property have already been validated by the discovery of the new Divisadero and Zata zones. It is becoming increasingly evident that the mineralizing events that occurred in the Nicho area are present at shallow depths elsewhere on our extensive property holdings. Once we complete the final compilation of the current data we look forward to the initiation of a Phase 2 drilling program."

All diamond drill samples were collected by Minera Alamos personnel including the Company's exploration geologists. Drill core samples were cut in half and divided into 1-2 m intervals. One half of the sample was bagged for analysis and the remaining half was logged by Minera Alamos personnel and stored for future reference. Blanks, duplicates, and standards were randomly inserted with the samples sent for analysis as part of the normal QA/QC procedures.

All samples were prepared and analyzed for gold using fire assaying with AA/gravimetric finish. All samples were sent for sample preparation at the ALS-Chemex facility in Hermosillo, Mexico.
