DEEPROCK COMPLETES PHASE 2 ON RALLEAU GOLD/VMS PROJECT

CONTIGUOUS TO OSISKO’S OSBORNE-BELL GOLD/VMS PROJECT

VANCOUVER, CANADA, September 5 , 2019 – DeepRock Minerals Inc. (the “Company”) (CSE Symbol:

“DEEP”), is pleased to announce that the second phase of its 2019 exploration program on the Rallea u

property is now complete except for the associated report. DeepRock’s Ralleau Gold/VMS project, located

in the Abitibi region of Quebec, just east of Lebel sur Quevillon , Quebec, adjoins the east boundary of

Osisko Metal’s Osborne-Bell Gold/VMS project.

Phase 2 exploration work consisted of prospecting and a detailed MMI s oil survey covering the eastern-

most claims surrounding the area of Sheillan Lake where in 2014, Megastar Development carried out a

mapping and prospecting program. This targeted area is underlain by Novellet Member rocks. This current

work will accommodate a more thorough understanding of the geological setting of the Ralleau Project in

anticipation of further diamond drilling.

It is understood that the Novellet Member comprises felsic units which may have an important association

with potential mineralization in a bimodal mafic VMS model as seen in the nearby world -class operating

Langlois Mine or the Osisko’s adjoining Osborne-Bell Deposit.

Access to the area covered being quite difficult, the geological team was moved in and out by helicopter

during this latest 2019 program.

A total of 111 soil samples has been collected and delivered to the SGS preparation laboratory in Val d’Or,

Quebec for analysis.

After preparation and drying, the soil samples will be treated by the SGS’s MMI geochemistry method.

Mobile Metal Ion (MMI) geochemistry is a proven advanced geochemical exploration technique known to

find mineral deposits. It is especially well suited fo r deeply buried mineral deposits. MMI™ measures

metal ions that travel upward from mineralization to unconsolidated surface materials such soil, till, sand

and so on. These mobile metal ions are released from mineralized material and travel upward toward the

surface. Using careful soil sampling strategies, sophisticated chemical ligands and ultra -sensitive

instrumentation, SGS can measure these ions. After interpretation, MMI data can indicate anomalous

areas.

Target elements are extracted using wea k solutions of organic and inorganic compounds rather than

conventional aggressive acid or cyanide -based digests. MMI solutions contain strong ligands, which

detach and hold metal ions that were loosely bound to soil particles by weak atomic forces in aque ous

solution. This extraction does not dissolve the bound forms of the metal ions. Thus, the metal ions in the

MMI solutions are the chemically active or “mobile” component of the sample. Because these mobile,

loosely bound complexes are in very low concentrations, measurement is by conventional ICP-MS and the

latest evolution of this technology, ICP-MS Dynamic Reaction Cell™ (DRC II™). This allows the lab to report

very low detection limits.

Assay Results from SGS are expected to be received shortly.

In addition to the referenced soil samples, the geological t eam took four grab samples for lithological

study. The four samples were delivered to the ALS laboratory in Val d’Or. They were tested for gold by the

Au-ICP22 method and by the Me-ICP06 method which is a whole rock package. No gold has been reported

from the four grab samples. Slight anomalous values in chromium, copper, manganese, tantalum,

titanium, vanadium and zinc can be observed.

A technical report covering the Phase 2 program is under preparation by MRB and Associates, from Val

d’Or.
