Atacama Begins 10,000-metre Diamond Drilling Program at its Cristina Project, Chihuahua Mexico
Atacama Begins 10,000-metre Diamond
Drilling Program at its Cristina Project,
Chihuahua Mexico
Vancouver, British Columbia--(Newsfile Corp. - March 12, 2024) - Atacama Copper Corporation (TSXV:
ACOP) ("
Atacama
" or the "
Company
") is pleased to announce the start of a 10,000-metre diamond
drilling program at its wholly-owned Cristina precious metals project in southwestern Chihuahua State,
Mexico (Figure 1). The Cristina project consists of multiple outcropping quartz veins that are frequently
greater than 10 metre in width and extend for a currently known strike length of up to five kilometres. At
least four parallel mineralized vein zones have been mapped and sampled to date, however most of the
resource estimate reported here is contained within the Guadalupe vein (Figure 2).
Tim Warman, Atacama's CEO, commented "The drilling program that started this week is aimed at
better defining and expanding the known higher-grade zones within the Guadalupe and Los Ingleses vein
systems. While the current resource is largely contained within a single modeled open pit shell on the
Guadalupe vein, we believe that there is excellent potential to define a higher-grade underground
resource at Cristina. Previous drilling has encountered thick higher-grade zones in every vein system
tested to date, and this current round of drilling is aimed at better defining and expanding those zones."
An interesting aspect of the Cristina deposit is the apparent vertical extent of the mineralisation within
the system. Mineralisation in outcrop occurs at surface at elevations up to 2,000 metres above sea level
(masl), while the deepest zone of mineralisation intercepted by drilling is at an elevation of 900 masl, a
vertical range of approximately 1,100 m.
The Cristina deposit is an epithermal to mesothermal vein system where the mineralisation is
predominantly gold and silver, with lesser base metal values. At least four parallel vein zones trend east-
west to northeast-southwest and are hosted in an andesitic volcanic sequence which forms part of the
Lower Volcanic Sequence of the Sierra Madre Occidental range. The andesites are intercalated locally
with dacitic intrusions and related lava flows and breccias, and the sequence is in turn cut by andesitic
and hornblende-plagioclase porphyry following fault trends. In some areas the veins are covered by post-
mineral rhyolite of the Upper Volcanic Sequence.
Cristina is similar to other active mines in the region including Fresnillo's San Julian and La Cienega
mines, as well as First Majestic's Tayoltita/San Dimas mine.
The goal of targeting the higher-grade zones within the main Guadalupe Vein, as well as other high-
grade veins in the area, is to both increase the size and the grade of the resource and demonstrate the
underground resource potential at Cristina. The current mineral resource estimate comprises:
Indicated resources of 17.5 Mt at 0.51 g/t gold, 33.8 g/t silver, 0.47% zinc, 0.19% lead and 0.04%
copper (1.33 g/t AuEq grade), for a contained 752,000 gold-equivalent ounces.
Inferred resources of 19.0 Mt at 0.51 g/t gold, 27.5 g/t silver, 0.50% zinc, 0.19% lead and 0.05%
copper (1.27 g/t AuEq grade), for a contained 777,000 gold-equivalent ounces.
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
The program is expected to continue over the next several months. Results from the drilling program will
be released periodically as they are received and analyzed.

About Atacama Copper Corporation
Atacama Copper is a well-funded resource company adding value through the acquisition, exploration,
and development of copper and precious metals projects in the Americas. The company is carrying out
an aggressive drilling campaign at its Cristina precious metals project in Chihuahua Mexico, with the
goal of significantly expanding the existing mineral resource estimate. Drilling is also planned for the
Yecora copper project in Sonora Mexico. In Chile, the Placeton/Caballo Muerto project hosts several
untested porphyry copper targets situated between the large-scale Relincho and El Morro/La Fortuna
copper-gold deposits of the Nueva Union joint venture between Teck and Newmont Mining.
