Monterey Minerals Completes Purchase of

323 square kilometres in the Pilbara region

of Western Australia

TORONTO, ON - June 6, 2019 - Monterey Minerals Inc. (the “Company” or “ Monterey”) (CSE:

MREY, FSE: 2DK ) is pleased to announce that it has completed the purchase of Gold River

Resources Pty Ltd. (“ Gold River ”). Monterey previously announced (see press release dated

April 2, 2019) that it would issue 11 million common shares for all of the shares of Gold River ,

which owns s ix tenements encompassing over 323 square kilometres in the Pilbara region of

Western Australia.

President and CEO, James Macintosh stated “ Our 992 sq. km tenement portfolio is located in

the “fairway” of the Pilbara Basin on strike with the Pilbara’s major players , who are actively

exploring the area with significant budgets. We anticipate announcing our exploration plans

during Q3 2019.”

Monterey Minerals Tenements in the Pilbara Basin

New Acquired - Gold River Tenements

E47/3958 and E47/3959, covering 218 km 2, abut Pacton Gold to the west and are just north of

Novo Resources. Locally, E47/3958 is 7 km to the north of De Grey Mining’s Withnell Mining

Centre that hosts over 445,000 ounces (“ozs”) of gold (Measured and Indicated) with another

429,000 ozs (Indicated) in a cluster of deposits (De Grey - 2018 Annual Mineral Resources

Statement). The mineralization hosted on adjacent and nearby properties is not necessarily

indicative or representative of mineralization that may be hosted on the Company’s properties.

Withnell is also the site of De Grey’s proposed gold processing facility (DEG March Quarterly

Report 2019). There is a prospective quartz vein in the centre of the property that can be

traced for over 400 metres at surface with evidence of artisanal mining. Pacton Gold’s

exploration in the adjacent area in similar-aged granitoids have found occurrences of swarms of

quartz veins, many of which host gold mineralization.

The tenements are situated wi thin the Central Pilbara Tectonic Zone and is underlain by the

sediments of the De Grey Superbasin and underlying granitic rocks that intrude the Supergroup.

Local lithologies include the Portee granitoid of the Sisters Supersuite and unclassified Mallina

Basin sediments which are the dominant host to gold mineralization in the area. Immediately to

the north of E47/3958 is the large regional structure of the Sholl Shear Zone which is the tectonic

boundary between the Central Pilbara Tectonic Zone, and the Karratha Terrane. The Portee

Granitoid is evident from the magnetics and has intruded the basin in multiple phases. It forms a

series of discrete “nested” ovoid plutons evident from their magnetic signature. Within these

plutons are potentially preserved roof pendants of the Mallina Formation providing exploration

targets for gold, antimony, and/or tin, tantalum, niobium mineralization. Other targets at the

project include semi preserved or partially assimilated rafts of greenstones, and faulted contacts

of the plutons and surrounding Mallina sediments. Anomalous levels of gold, tin, and tantalum

were recorded adjacent to the south-east corner of E47/3958.

E47/3960, covering 64 km2, abuts Kairos Minerals’ Croyden project, which hosts gold with

conglomerates, and is just northwest of Pacton Gold’s tenement E47/3905. The Hardy

Formation outcrops within 1 km of the western boundary of the lease. The conglomerates of

the Hardy Formation have been targeted historically for gold and uranium mineralization . The

tenement is underlain by the Powder Monzogranite of the Yule Granitoid Complex (2,935 Ma)

which includes porphyritic and seriatic textured monzogranites cross -cut by Proterozoic

doleritic dykes. Swarms of pegmatites , which occur locally and in close proximity to the SE

corner of the lease, are the historic Mumbillia Lithium bearing pegmatite mine workings.

E45/5180, covering 6 km 2, abuts a Novo Resources tenement to the northwest and is adjacent

to Novo Resources’ Talga Talga Mining Centre, located 20 km north of the town of Marble Bar.

The Talga Talga Mining Centre and E45/5180 are situated within the greenstone belts

surrounding the Mt Edgar Granitoid Complex. The historic workings at Talga Talga were mined

until 1940 with 1,614 ozs of gold mined from 1,432 tonnes of ore for an average grade of 35.1

grams per tonne of gold (ASX:TLG - Talga Gold Limited Prospectus). The mineralization hosted

on adjacent and nearby properties is not necessarily indicative or representative of

mineralization that may be hosted on the Company’s properties.

E46/1243, covering 3 km 2, sits within the Middle Creek mineralized corridor of the Mosquito

Creek Formation. The Middle Creek mineralized corridor is known to host over 745,0 00 ozs of

gold (Measured and Indicated) with another 410,000 ozs (Inferred) in numerous deposits

currently being mined by Millennium Minerals, who are targeting gold production of 90,000 ozs

to 100,000 ozs in 2019 (ASX:MOY - 2018 Ore Reserve and Mineral Re source Statement). The

mineralization hosted on adjacent and nearby properties is not necessarily indicative or

representative of mineralization that may be hosted on the Company’s properties. E46/1243

sits in close proximity to a major structural offset of the Blue Spec Fault, a well mineralized

structure which hosts the Blue Spec Gold Mine.

E46/1244, covering 32 sq.km., is 5 km south of the Mosquito Creek Formation. The ground is

underexplored and the only previous exploration was regional stream sediment sampling and

bulk sampling for diamonds by DeBeers Australia Ltd. The Sandy Creek Cu- Pb-Zn-Ag (copper,

lead, zinc & silver) prospect is 7 km to the east of the project.

About Monterey Minerals Inc.

Monterey Minerals is a mineral exploration company focused on its prospective 992 sq. km.

Pilbara Basin tenement portfolio on the eastern flank of the Pilbara Basin in Western Australia,

Smithers, BC. The Company’s NI 43 -101, on SEDAR, notes historic sampling at the Project that

returned mineralized showings of gold, silver, copper, zinc and cobalt.
