For Immediate Release
DEEPROCK COMMENCES HIGH-RESOLUTION HELIBORNE
MAGNETIC SURVEY OVER ITS RALLEAU GOLD/VMS PROJECT
VANCOUVER, CANADA, September 24, 2019 – DeepRock Minerals Inc. (the “Company”) (CSE
Symbol: “DEEP”), is pleased to announce that the Company has engaged the services of
ProspectAir based out of Gatineau, Quebec to commence immediately a specialized High -
Resolution helicopter-borne geophysical survey on its Ralleau VMS/Gold Project.
DeepRock’s Ralleau Project is ideally and strategically located in the Abitibi region of Quebec, just
east of the regional centre of Lebel sur Quevillon. The Ralleau Project is centrally situated so that
it straddles both the Cameron and Barry Deformation Zones ; and as well adjoins both the east
boundary of Osisko Metal’s Osborne -Bell Gold/VMS project and the west boundary of Osisko
Metal’s Windfall Lake Gold Project.
The heliborne survey, will be flown with tight 50-metre line spacing and carried out with traverse
lines oriented N015 in order to capture the desired, detailed mapping of the dominant
magnetic/geological stri ke. Control lines for the survey will be flown perpendicular to the
traverse lines and at a 500 m line spacing. This survey is designed to take in the entire Ralleau
Project by encompassing a total survey distance of 1,013 linear-kilometers of flight lines.
ProspectAir will utilize its Geometrics G -822A heli borne magnetome ter for the project . This
particular heliborne magnetic sensor consists of a non -oriented (strap-down) optically-pumped
Cesium split-beam sensor. These specialized magnetometers have a high resolution sensitivity of
0.005 nT and a range of 15,000 to 100,00 0 nT with a se nsor noise of less than 0.02 nT. The
heliborne sensor is mounted in a ‘bird’ made of nonmagnetic material located 21 m below the
helicopter when in flight. Total magnetic field measurements are recorded at 10 Hz in the aircraft.
The ground system will be recording magnetic data at speed of 1 sample every second.
ProspectAir’s crews will fly the helicopter at approximately 120 km/h in gentle terrain. Under
these conditions, the distance between samples taken along the survey flight lines will typically
be very 3.3 meters.
For MAG only data acquisition, the nominal terrain clearance of the helicopter will be set to 51
metres with smooth line -to-line compatible draping of topography. The nominal mag detector
ground clearance will the refore be approximately 30 meters. Altitude shall be ultimately
controlled at the discretion of the helicopter pilot with safety held in priority consideration.
High resolution heli borne magnetometer surveys like DeepRock is undertaking on its Ralleau

Project can play an extraordinarily important part in quality exploration program s. Recent
improvements in magnetometer design have resulted in the delivery of impressive and accurate
data, which when combined with GPS , yields significantly enhanced aeromagnetic maps. The
overall improvement s in accuracy and precision , in recent years, has frequently warranted
resurveying areas which were flown using outdated instrumentation and methods now
considered obsolete.
High resolution aeromagnetic maps today reflect the underlying geology regardless of the degree
of exposure. They play such an important role in interpreting geological structures and rock type
distribution that high-resolution magnetometer surveying can truly be called a primary, universal
exploration tool.
The Ralleau property represents a favorable setting for bimodal mafic VMS mineralization
similar to the Langlois mine located just WNW of DeepRock’s Ralleau Project.
Felsic volcanic rocks displaying characteristic h ydrothermal alteration, known to be associated
with Volcanic Massive Sulphide ( “VMS”) style deposits, has been identified from the geological
review, diamond drilling and trenching.
DeepRock’s new heliborne survey will provide DeepRock’s team of geoscientists with a very
accurate and precise picture of the different rock units underlying the Ralleau Project as well as
the presence of structures suc h as folds and faults, often not visible in the field because of the
thick overburden. Mafic rocks are generally magnetic while felsic rocks may correspond to lower
magnetic intensities.
This heliborne survey , about to be undertaken by DeepRock , will be utilizing the same
configuration of equipment and instrumentation as the one that was utilized over Bonterra’s
Gladiator project, which lead to the discovery of several gold mineralized zones. Bonterra’s highly
successful Gladiator Project is located in the Urban-Barry area, to the east of DeepRock’s Ralleau
Project.
