PRESS RELEASE TSXV, BVL: ALT
Alturas Signs agreement for the Resguardo Copper-Gold Project in the
Paleocene-Eocene Metallogenic Belt of Northern Chile
Toronto, December 18, 2023 – After a long negotiation and due diligence period, Alturas Minerals Corp.
(Alturas or the “Company”) (TSX-V, BVL: ALT) is pleased to announce that is has moved forward with the
execution of the Option and Lease agreement with Sociedad Contractual Minera Resguardo (“ Minera
Resguardo” or the “ Optionor”), a Chilean mining exp loration company, to lease and acquire 100% of its
Resguardo Copper-Gold Project (the “Concessions” or “Resguardo”), located about 95 km northeast of
Copiapo, in Region III of northern Chile, referred to as “Región de Atacama”.
The transaction remains subject to regulatory and TSX -V approvals, which is in the process of reviewing
all the required documentation. Closing will occur on receipt of these approvals.
Alturas is exploring the possibility of obtaining a permit to extract ore from the existing open pit mine on
the property within six to nine months to generate cash flow to fund Alturas’ future costs”.
As part of its due diligence, the Company has initiated environmental permitting, delineated target areas
and defined its exploitation and production approach.
Miguel Cardozo, President & CEO of Alturas commented , “The Resguardo project represents a key
strategic development for the Company in Chile, one of Latin America’s premier mining jurisdictions.
Alturas will resume its exploration activit ies in Chile’s mineral-rich Andes Mountain chain. The
agreement also includes a 4-year mining lease agreement that allows the Company to explore and
commercially mine 18 contiguous mining concessions covering a total of 3,891 hectares. Alturas intends
to establish a firm presence in the Paleocene-Eocene Metallogenic Belt of northern Chile, immediately
west of the Miocene age Maricunga Metallogenic Belt”.
The Transaction
With the execution of the Agreement, the Optionor grant Alturas a mining option (the “Option”) to
acquire a one hundred percent (100%) undivided interest in the Concessions. On closing, t he Option will
be valid as from May 31, 2023 (the “Effective Date”) and will expire four (4) years after the signing of the
Agreement. The term of the Option shall be mandatory for the Optionor and voluntary for Alturas.
The aggregate purchase price for the Concessions is structured as cash payment s totaling US$2.75
Million (all taxes inclusive), to be paid in five (5) installments, with US$50,000 within f ifteen days of the
2
closing date (of which $25,000 has been paid as deposit with the balance held in escrow) , and four (4)
installments payable as follows:
• On or prior to the first anniversary of the Effective Date, the amount of US$100,000;
• On or prior to the second anniversary of the Effective Date, the amount of US$150,000;
• On or prior to the third anniversary of the Effective Date, the amount of US$300,000; and,
• On or prior to the fourth anniversary of the Effective Date, the amount of US$2,150,000.
If, as a result of the mining activities performed by Alturas on the Concessions, a porphyry is confirmed,
the purchase price for acquiring title over the Concessions payable by Alturas to the Optionor will be
increased by ten percent (10%) of the selling price obtained by Alturas for the transfer of the
Concessions to a third party, or US$30 Million, whichever is greater.
Once the Company exercises the Option, a 1.5% Net Smelter Return (“NSR”) Royalty will be applicable
(the “NSR Royalty”) as an additional consideration for the transfer of the Concession to be effective as
from commencement of Commercial Product ion on the Concessions. Until up two (2) years after the
commencement of Commercial Production, the Company may buy five tenths’ percent (0.5%) of the
NSR Royalty (the “Purchased NSR”) at a price between US$2 Million and US$6 Million depending on the
size, grade, and type of mineralization as determined in accordance with National Instrument 43-101
(“NI 43-101”). The Optionor also grants a right of fir st refusal for the acquisition of the remaining NSR
Royalty.
Mining Lease:
During the term of the Option, the Optionor shall also lease the Concessions (the “Mining Lease”) to the
Company, as result of which Alturas will be conferred all the rights and obligations of the Optionor
related to the Concessions, including the right to exploit the Concessions.
The Mining Lease shall be for a period of five (5) years and begins on the Effective Date or, whichever
arrives first, when Alturas notifies the Optionor of its decision to exercise the Option.
Once the Mining Lease is in force, Alturas shall have the right to operate the Concessions at its own sole
cost and risk, subject to compliance with applicable laws, shall have the right to initiate commercial
production of the existing high-grade copper mineralization.
As compensation required for the Mining Lease, Alturas will pay the Optionor a NSR Royalty over all the
minerals extracted and marketed from the Concessions (the “Lease NSR Royalty”). If the mineral
extracted has an average ore grade that is lower than 2.5%, the Lease NSR Royalty will be equivalent to
7.0% of the price at which said mineral is marketed; and, if the mineral extracted has an average ore
grade that is equal to or higher than 2.5%, the Lease NSR Royalty will be equivalent to 9.0% of such
price.
Resguardo Geology and Mineralization
Copper structures on the Resguardo consist of sub -vertical and tabular stockwork bodies (in parts
hydrothermal breccia) that host disseminated and vein co pper mineralization exceeding 2.0% Cu, along
with sub -parallel copper- gold veins. The main mineralized copp er body, which has been historically
3
mined, has an average width of 50 to 100 m and is about 1.5 km in length . Historical open pit and
underground mine workings are scattered along the 1.5 km length with areas of mineralization that
often exceed 2.0% Cu-equivalent grade.
Besides exploring the high -grade copper structures and the potential copper porphyry system, the
Company intends to undertake an ini tial small-scale mining operation of the high -grade material. The
maximum tonnage allowed by Chilean regulations is 5,000 tonnes per month. This activity will be of
great help in defining the actual extension and quality of the high -grade copper mineralization with the
view of a future mid-size operation and will generate significant cash-flow to the Company to support its
activities in the Concessions and future exploration projects in Chile.
Given the already known copper mineralization at or near surface and the extensive and intense
hydrothermal alteration covering kilometres of area, there is a high probability that known copper oxide
and sulphide mineralization is genetically connected to a yet unconfirmed porphyry system (i.e., Late
Eocene-Early Oligocene) located topographically lower and therefore deeper in the mineralized system.
Evidence for the possibility of a porphyry system is supported by recent induced polarization and
magnetic geophysical surveys which have delineated a deep -seated chargeability high overlapping the
edge of a magnetic low, the latter which was likely produced by magnetite dest ruction as a result of
hydrothermal fluid movement.

The Resguardo Copper-(Gold) Project and the Paleocene-Eocene Metallogenic Belt (“PEMB”)
The Resguardo Project is located about 45 km southwest of La Coipa Au- Ag Mine (Kinross Gold Corp: Compañía
Minera Mantos de Oro) and about 85 km northeast of Candelaria Copper Mine (Lundin Mini ng)”. Access to the
Resguardo Copper Project is excellent, starting from the southeast end of the City of Copiapó, travelling northeast
on highway 31 for about 85 km to the Quebrada Cortadera access road. Heading northwest on the Quebrada
Cortadera access road for about 5.5 km brings you to the central area of the Project and the historical workings at
the historical mine site. The Project is currently at the exploration stage and Optionor ship of surface rights are
usually not contemplated or necessary unti l a decision to mine has been made. The Mining Code of Chile
guarantees the Optionor of mining concessions the right-of-access to the surface area required for their exploration
and exploitation.
The Resguardo Copper Project lies within Paleocene- Eocene Metallogenic Belt of northern Chile, immediately west
of the Miocene age Maricunga Metallogenic Belt (see Figure 1) . The Project is within the morpho structural zone
known as the Cordillera Domeyko (aka Andean Pre- Cordillera), a region underlain by Paleocene, Eocene and Early
Oligocene Epoch magmatic arc rocks comprising a north -south linear belt. Rocks consist of basaltic to rhyolitic lavas
and tuffs, subvolcanic porphyritic intrusions, and granitoid stocks, which extend from southern Peru to central Chile.
The Paleocene- Eocene porphyry and epithermal Metallogenic Belt hosts a diverse range of mineral deposits and
occurrences, including large-scale porphyry Cu-Mo deposits like BHP Billiton’s Spence Mine (e.g., Sillitoe and McKee,
1996) and Codelco’s El Salv ador Mine (e.g., Gustafson and Hunt, 1975) and low sulphidation epithermal deposits
like Yamana Gold’s El Peñon (e.g., Warren et al., 2004, 2008).
On the Property, in the areas around the historical underground and open pit mines, rocks have experienced
pervasive and intense hydrothermal alteration that includes sericitic, silicic -argillic and propylitic alteration. In the
copper mineralized zones, th e host rock generally shows a hydrothermal alteration of the silicic -argillic type that
4
grades laterally to an aureole of weak and irregular propylitic alteration (with epidote and chlorite). Hydrothermal
alteration (both silicic -argillic and propylitic) of the host rock in the extreme western parts of the Property is much
less intense and locally non-existent.
A complex mineralized system dominated by copper but with ancillary gold and silver mineralization exists on the
Resguardo Copper Project, with muc h of the known mineralization focused in the area of the historical workings
and underground mine. Most copper mineralization occurs as disseminated and veinlet copper oxide species but
stockworks, hydrothermal breccias and larger vein systems are also known to occur (Frutos, 2014).
The main east -west mineralized trend, referred to as the Cerro Fraga Mineralized System (“CFMS”), extends for
more than 2 km and with widths from 300 to 500 metres (Frutos, 2014). This copper zone is characterized by areas
of intense hydrothermal alteration with upper areas of oxidized and leached lithologies, hydrothermal breccias, and
veins and stockworks. The main mineralization that has been historically targeted consists of copper oxides and
copper sulphides which in some areas carry important concentrations of silver and gold in structurally controlled
veins that have been historically worked by artisanal miners.
Within the CFMS, principal copper structures consist of sub- vertical and tabular stockworks bodies (in parts
hydrothermal breccia) that are interpreted to be structurally controlled (east -west and sub- vertical), with
disseminated and vein copper mineralization, and sub- parallel veins of copper -gold trending N70 -100E (Frutos,
2014). The main mineralized copper body which has been historically mined has an average width of 50 to 100 m
and is about 1.5 km in length, with good outcrops and several historical open pit and underground mine workings
scattered along its length.
The principal deposit type being explored for on the Property is Porphyry Copper Deposit or “PCD”. Mineralized
systems associated with a PCD system commonly include polymetallic skarn, carbonate replacement and
stratabound (i.e., Manto -style copper), sediment -hosted gold silver, and high, intermediate and low sulphidation
epithermal silver-gold-base metal deposit types (Sillitoe and Perello, 2005; Sillitoe, 2010).
Mineralization styles (replacement Manto -style copper with pervasive disseminated copper oxides and sulphides
and veining) and intense hydrothermal alteration (alunite, kaolinite, illite, lesser propylitic) observed in the
historical workings on the Property, coupled with recent evidence from geophysical surveys support the PCD model
and provide targets for a future exploration program.
The Project area has sufficient size to accommodate a mining operation without any negative impact on the
environment. The area corresponds to the high desert climate of the Atacama Region with only trace rainfall most
of the year and with most precipitation as minor snow in winter months (June- September). Given its excellent
accessibility and climate, all types of exploration activities can be performed year-round.
The Resguardo Copper Project does not have any current mineral resources or mineral reserves and despite having
some historical copper production, is best described as an early -stage exploration project. Historical exploration
work (geological mapping, trenching, geophysical surveys, drilling) and small -scale copper mining is known to have
been completed within the Project area, dating back decades and most recently in 2020. Most of the information
and data available from historical exploration work on the Property begins with SCM’s Optionorship in 2012:
