Regulus Announces Delivery of Phase Two Metallurgical Samples to Nuton LLC, a Rio Tinto Venture
NEWS RELEASE
Regulus Announces Delivery of Phase Two Metallurgical Samples
to Nuton LLC, a Rio Tinto Venture
VANCOUVER, BC / November 7, 2023 / Regulus Resources Inc. ("Regulus" or the
"Company") (TSX-V:REG)(OTCQX:RGLSF) is pleased to announce that it has delivered
samples to Nuton LLC ("Nuton"), a Rio Tinto venture, to begin the phase two metallurgical
program utilizing Nuton's proprietary primary sulphide leaching technologies. The phase one
metallurgical program (See July 6, 2023 press release) determined that mineralization from
AntaKori was amenable to Nuton's sulphide leaching technologies, while the phase two
program is designed to expand on the results from phase one and refine the understanding
regarding metallurgical recoveries for various styles of mineralization.
Sample Selection, Preparation, and Methodology
Samples were selected and composited from each of the main mineralization styles at the
AntaKori project: high sulphidation, skarn and porphyry. A total of eight composite samples
were taken totaling 1,448.7 kg (see Table 1 for sample details and Figures 1 and 2 for sample
locations). All samples were taken from Regulus drill hole core stored in the Company's
Cajamarca warehouse. The samples were shipped to SGS laboratories in Lima Peru for
further sample preparation according to Nuton specifications and protocols, under the
supervision of Transmin Metallurgical Consultants S.A.C. Once the samples have been
prepared in SGS Lima, a small representative sample split will be sent to Nuton for detailed
chemical and mineralogical analyses of each of the composite samples before
commencement of the main phase two column test work. Chemical and mineralogical data
will be used to predict column test results.
The remaining prepared samples will be shipped from SGS Lima to Nuton's test facilities for
phase two test work, which will entail samples being placed in columns with a height of 1 m,
each under different controlled Nuton operating conditions. The columns will be
continuously monitored and it is expected that once samples are placed into columns, the full
results will be available approximately one year later.

About Nuton
Nuton is an innovative venture that aims to help grow Rio Tinto's copper business. At the
core of Nuton is a portfolio of proprietary copper leach related technologies and capability - a
product of almost 30 years of research and development. Nuton offers the potential to
economically unlock copper from primary sulfide resources worldwide through leaching,
achieving market-leading recovery rates, contributing to an increase in copper production
from copper bearing waste and tailings, and achieving higher copper recoveries on oxide and
transitional material. One of the key differentiators of Nuton is the potential to produce the
world's lowest impact copper while having at least one Net Positive impact at each of our
deployment sites, across our five pillars: water, energy, land, materials and society.
