NGEx Minerals Announces Assay Results from Previously Unsampled Geotechnical
Drill Holes into High-Grade Core of Los Helados Deposit: including 440m @ 1.03%
CuEq (0.82% Cu, 0.31 g/t Au, 2.9 g/t Ag)
VANCOUVER, SEPTEMBER 8, 2021 - NGEX Minerals Ltd. (TSXV: NGEX) (“NGEx Minerals” or the “Company”)
is pleased to provide an update and review of its Los Helados copper-gold project located in Chile , including
new assay results from previously drilled, but unsampled, geotechnical drill holes. These two holes were
drilled in 2015 to collect whole-core geotechnical data and were left unsampled. They have now been assayed
and will be incorporated into an upcoming resource update. Both holes intersected the high-grade core of the
deposit and are infill holes which are expected to result in the conversion of part of the resource from the
Indicated to Measured category.
Wojtek Wodzicki, President and CEO, commented “These drill holes serve as a timely reminder of the grade and
scale of the high-grade core of the Los Helados deposit and the significance of Los Helados as part of an emerging
cluster of major copper-gold-silver deposits including Filo del Sol and Josemaria controlled by other entities within
the Lundin Group of Companies and the Caserones Deposit controlled by Nippon Caserones Resources, NGEx
Minerals’ partner at Los Helados. Very few major copper deposits are controlled by junior exploration companies
and we believe that the global scarcity of large scale copper development projects and the current strong outlook
for copper means that Los Helados will have an important role to play in the development of this exciting new
district.”
The assays are highlighted by the following:
• LHDHG02A was mineralized throughout its entire length, returning 1,101m @ 0.70% CuEq (0.52% Cu,
0.28 g/t Au, 1.7 g/t Ag) , including a high -grade interval of 224m @ 1.04% CuEq (0.79% Cu, 0.37 g/t
Au, 2.7 g/t Ag)
• LHDHG03 was also mineralized throughout its entire length, returning 1,134m @ 0.79% CuEq (0.59%
Cu, 0.30 g/t Au, 1.9 g/t Ag) , including a high-grade interval of 440 m @ 1.03% CuEq (0.82% Cu, 0.31
g/t Au, 2.9 g/t Ag)

The high-grade intervals noted above intersected a distinct matrix-rich phase of the breccia body that forms the
higher grade core of the Los Helados resource (refer to attached figure) This phase was identified during a
relogging program completed during 2020. The relogging program was focused on better defining the internal
architecture of the Los Helados breccia body, and resulted in an improved geological model which will also be
incorporated into the planned resource update.
Previous engineering studies on Los Helados focused on large scale mining of the overall resource. O nce the
resource update is finalized the Company plans to evaluate the potential to develop a smaller scale mine plan
focused on the high-grade core of the deposit which could potentially lead to lower development costs and shorter
development timelines.
Los Helados Project Overview
Los Helados is one of the largest undeveloped copper-gold-silver deposits in the world, and it is management's
view that that the value of existing deposits, like Los Helados, which are located in favorable mining
jurisdictions, should be enhanced as positive market trends accelerate. Other considerations include:
Very large resource base: Los Helados is one of the largest undeveloped copper -gold-silver deposits in the
world containing:
• Indicated Resources1 of: 17.6 billion pounds of copper; 10.1 million ounces of gold; 92.5 million ounces
of silver.
• Inferred Resources1 of: 5.8 billion pounds of copper; 2.7 million ounces of gold; 35.1 million ounces of
silver.
Higher current prices plus a strong outlook: The prices used to originally evaluate Lo s Helados
were US$3.00/lb copper and US$1,300/oz gold. Current spot prices are approximately US $4.20/lb copper
and US$1,800/oz gold.
High value clean concentrate: Los Helados would produce a clean gold and silver rich copper concentrate low
in impurities. Impurities such as arsenic are a growing problem for smelters, and clean concentrate such as
that from Los Helados is expected to be in high demand.
Close to existing mining infrastructure: Los Helados is located approximately 12 km from the Caserones Mine
owned by Nippon Caserones Resources, which is NGEx Minerals' 36% partner at Los Helados.

• 1CuEq - Copper Equivalent is calculated using US$3.00/lb copper,
US$1,300/oz gold and US$23/oz Ag, and includes a provision for selling
costs and metallurgical recoveries corresponding to three zones defined by
depth below surface. The formulas used are: CuEq% = Cu% + 0.6264*Au

0.6366*Au (g/t) + 0.0077*Ag (g/t) for the Intermediate Zone (~250m to

• 2Cutoff grades refer to diluted cutoff grades used to generate the
corresponding cave shapes. For each cutoff grade, the tonnes and grade
represent the total Indicated or Inferred undiluted material within each of
these shapes;
• Small discrepancies may exist due to rounding errors;
• Mineral Resources are reported within block cave underground mining
shapes based on diluted CuEq grades, $13.07/tonne operating costs and
including a provision for capital expenditure. The base case cutoff grade of
0.33% CuEq was derived through an economic evaluation of several block
cave shapes developed over a range of different cutoff grades and is the
cutoff grade which results in a zero NP; and

Both these holes intersect part of a very large breccia body, and both are interpreted to represent the true
width of the mineralization at these locations.
Copper Equivalent (CuEq) for drill intersections is calculated based on US$3.00/lb Cu, US$1,500/oz Au and
US$18/oz Ag, with metallurgical recoveries of 88% for Cu, 76% for Au and 60% for Ag, based on extensive
metallurgical testwork. The formula is: CuEq % = Cu % + (0.6297 * Au g/t) + (0.006 * Ag g/t).
