DeepRock Minerals Completes High-Resolution Drone-Supported Magnetometer Survey

on the Golden Gate Project in New Brunswick, Canada

December 9th, 2022 - Vancouver, British Columbia - DeepRock Minerals Inc. (“DeepRock” or the “Company”) (CSE

Symbol: “DEEP”), is pleased to report that EarthEx Geophysical Solutions Inc. (“EarthEx”), based in Selkirk, MB,

has completed a detailed drone-supported airborne magnetometer survey (“Mag Survey”) of its Golden Gate Project,

located from 5 to 10 km west of Bathurst, New Brunswick.

The Mag Survey was carried out over approximately 10 km2, which covers the Company’s primary target area that

extends 6+ km east-northeasterly from the Falls Grid property to the southeastern boundaries of the Lugar property.

The Mag Survey was flown with a line spacing of 25 m and tie lines spaced 250 m apart. The program was designed

to acquire more total magnetic data at a lower altitude than conventional fixed-wing or helicopter-supported surveys,

providing improved and higher-resolution interpretations of the magnetic signatures over large structures within the

target area.

EarthEx’s proprietary method of data acquisition and interpretation offers 3D inversions of magnetic data with

reportedly more spatial precision than other conventional 3D inverted data, including the depth to the magnetic source

and the dip, size, and shape of a magnetic body.

The final interpretations and reporting of the Mag Survey results are anticipated in these next coming weeks. These

results will be correlated with the reconnaissance geological mapping and sampling work that was carried out prior to

the Mag Survey. The intent of the 2022 geophysical and geological surveying was to design and prioritize exploration

targets for drill testing in 2023.

Doug Blanchflower, P. Geo., a Qualified Person in accordance with National Instrument 43-101, has reviewed and

accepted the technical material contained in this news release.
