Nobel Resources Issued Diamond Drill Permits FOR Cuprita Project, Antofagasta Region, Chile
NOBEL RESOURCES ISSUED DIAMOND DRILL PERMITS FOR
CUPRITA PROJECT, ANTOFAGASTA REGION, CHILE
TORONTO, ONTARIO October 21, 2025 – Nobel Resources Corp. (TSX – V: NBLC) (the
“Company” or “Nobel”) is pleased to announce all necessary permits have been received
to commence drilling at Cuprita (the “Project”) as early as November . This will be the first
ever drill campaign at Cuprita. A notice was filed by the Company with the Copiapo office of
Servicio Nacional de Geologia y Minera (SERNAGEOMIN) during the week of Oct 12 th. The
Company intends to move quickly and drill the highly perspective Cuprita project. The first
phase of drilling on C uprita is expected to include diamond drill holes drilled from eight
initial platforms, additional platforms will be added based on results.
About Cuprita
Curprita is a highly prospective copper porphyry project in the Atacama region of northern
Chile. Cuprita is part of the Metallogenic Paleocene Porphyry Copper Belt that hosts several
major porphyry copper deposits such as El Salvador, Cerro Colorado, Spence, Sierra Gorda,
Fortuna, as well as several gold deposits. The Project sits on a very important north-
northeast trending major structur al corridor crosscut by a Northwest trending secondary
structure. This structural setting i s almost identical to the structural setting of the world
class Spence, Sierra Gorda and El Salvador porphyry deposits to the north. Nobel geologists
have identified multiple key geologic characterist ics consistent with a potentially buried
porphyry.
During recent field campaigns, Nobel geologists identified a leach cap at Cuprita with an
associated copper, lead and zinc anomaly in soils. The leach cap and soil anomaly are
located adjacent to a ground magnetic low and are situated near the intersection of a major
north-northeast striking fault structure with numerous northwest striking quartz veins with
copper oxides. Intersecting major faults is a common, if not essential, structural control for
the emplacement of copper-gold porphyries in the region (Figure 1).
The presence of strongly anomalous copper in soil on the flanks of the leach cap is an
important positive indicator supporting the potential for a buried mineralized porphyry
deposit at the Cuprita project. The highest copper in soils values identified to date occur
southeast of the outcropping leach cap (Figure 1) . Much of the soil anomaly exhibits soil
values more 300% above the expected background levels of the area. In addition, the leach
cap and soils anomaly are coincidental with a ground mag netic low (figure 2) which is a
common indicator associated with mineralized systems in the region, where hydrothermal
processes have replaced the magnetic minerals.
The presence of a leach cap at Cuprita is exceptionally encouraging in a regional context.
Leach caps are a key feature of intact porphyry systems in this region (Figure 4, Conceptual
Model). Recirculation of acidic fluids from the buried porphyry below often leave a bleached
or iron oxide “rusty” appearance on surface. The leach cap identified by Nobel geologists
exhibits classic hydrothermal alteration similar to that found above a buried porphyry. The
presence of copper oxides, quartz veins and remanent sulfides indicates potential for
mineralization under the leach cap, which fits the classic geological model for the region.
Geological mapping has also identified a large area of tourmaline breccias covering much
of the target , also considered an additional favorable pathfinder, characteristic of
productive porphyry systems.
Larry Guy, Chaiman and CEO of Nobel, states: “With the field work now completed and drill
permits in hand we are very excited to be the first to drill Cuprita. The classic signature of a
buried porphyry at Cuprita can’t be ignored. We are excited to get the drill turni ng. Nobel’s
outstanding portfolio of additional exploration projects in Chile will be tested in 2026.”
