Monumental Minerals Finalizes Follow-up Exploration Plan at the Laguna Blanca Project, Lithium Triangle, Chile
MONUMENTAL MINERALS FINALIZES FOLLOW-UP EXPLORATION PLAN AT
THE LAGUNA BLANCA PROJECT, LITHIUM TRIANGLE, CHILE
News Release - Vancouver, British Columbia – June 29, 2022: Monumental Minerals Corp.
(“Monumental” or the “Company”) (TSX-V: MNRL; FSE: BE5; OTC: MNMRF) is pleased to announce
plans for a follow-up exploration work program at the Laguna Blanca lithium (Li) brine and cesium (Cs)
sediment project (the “Project”), located within the Lithium Triangle, northern Chile.
The Laguna Blanca Project is within the eastern Andean Geomorphic Belt of Chile’s Central Andean Altiplano
and is located 120 km from the Salar de Atacama, the largest producing salar in the world. The felsic volcanic
rocks of the Central Andean Altiplano are enriched in Li and Cs. Seasonal rain and snow melt leaches and
transports Li, Cs, Ca, Na, Mg, K, and B from rock units into the enclosed Laguna Blanca salar. With no outlets,
evaporation concentrates these elements within mineral-rich salar brines.
On June 18 and 19, 2022, Monumental hosted a site visit to the Laguna Blanca Project (Photo 1) for the
Company’s Chilean team, in order to formulate an exploration work program. The objective of the program
is to develop drilling targets by confirming existing areas of interest and by establishing additional targets
within the concessions that fall under the Company’s option agreement with Lithium Chile Inc.

The Company’s Chilean team includes:
• Caracle Creek Chile SpA: Monumental’s local Chilean exploration consulting and project
management group.
• Atacama Water SpA: Hydrogeological site characterization and brine resource evaluation.
• Satelite SpA: Specialized in sustainable advancement of the Project including social, community,
and environmental terms to build solid links and relationships with our stakeholders.
Dr. Jamil Sader, CEO and Director of Monumental, comments:
“We look forward to advancing our Laguna Blanca Project utilizing TEM geophysics and near -
surface brine and sediment geochemistry. The results from this exploration work program will be
quickly translated into the delineation of multiple drilling targets. Monumental’s high-performance
Chilean team have been instrumental in the planning of our field work program, and they are a key
part of our success in Chile to date and will be in the future.”
The work program is set to commence immediately with the objective to collect additional near -surface
brine and sediment samples for geochemical analysis. The sample locations will be strategically selected to
build on the previous sampling conducted by Lithium Chile Inc., within the 9 square km highly prospective
area (see Monumental Minerals press release dated June 7, 2022). Samples will also be collected based on
assessments of the basin and on a transient electromagnetic (TEM) geophysical survey previously carried
out by Lithium Chile Inc. in 2019 (Figure 1). Conductive anomalies from that survey occur from less than
100 to 150 m below ground surface and have strike lengths of several kilometres (Figure 1).

survey completed by Lithium Chile Inc. From top to Bottom, lines #1, #2 and #3. RIGHT: Location of surface traces
(pink) of the TEM survey lines. The hot colours (pink, red, orange, yellow) in the cross sections indicate a conductive
anomaly at depths of less than 100 m from ground surface and suggest a strike length of several kilomet res with
thickness of more than 400 metres.
Transient Electromagnetics (TEM), also referred to as Time Domain EM (TDEM), is an electromagnetic
geophysical method which utilizes a controlled inductive source to generate diffusion and/or eddy currents
in the subsurface whose secondary magnetic field response is then measured. The electromagnetic
responses from TEM surveys and subsequent modelling are highly effective in delineating the locality and
thickness of brine aquifers. Brine fluids contain high concentrations of elements including lithium, cesium,
and boron, which conduct electrical currents more efficiently than fresh water or silicate rocks. Thus, highly
conductive zones in the subsurface, in conjunction with high lithium contents from surface sampling,
present compelling targets for drilling and follow-up exploration.
Monumental Minerals Corp. has granted incentive stock options to certain of its directors and consultants
to purchase up to an aggregate 35,000 common shares of the Company at a price of 45 cents per common
share for a period of three years, with the options vesting immediately.
Methodology and QA/QC
At Laguna Blanca, Transient Electromagnetic (TEM) surveys were conducted in 2019 using a 200-metre
coincident square moving loop configuration with contiguous (back -back) moving loops , acquiring the
vertical component of dB/dt data at frequencies of 1 and 4Hz , using a Zonge, GDP-32II 16-bit receiver,
and Zonge, ZT-30 transmitter. A series of 3 northeast-southwest oriented lines comprising 67 TEM stations
over 13 line-km were completed. 1D smooth -model inversion (STEMINV v3.00, Scott MacInes, Zonge)
was used for converting TEM measurements into resistivity versus depth information within Geosoft Oasis
Montaj software.
