Majuba Hill Copper Completes Copper
Global Mineral Inventory Estimate
VANCOUVER, BC — September 20, 2022 — Majuba Hill Copper Corp. (CSE: JUBA /
OTC: JUBAF / FWB:4NP) (“Majuba Hill Copper” or the “Company”) is pleased to report
results from the Company program to evaluate the mineral potential at the Majuba
Hill Porphyry Copper Project in Pershing County, Nevada.
A property-wide mineral inventory was completed as an exploration guide for Majuba
Hill Copper’s on- going drilling program. It is a non- compliant NI43-101 global
estimate; these are not mineral resources or mineral reserves and they do not
demonstrate economic viability. The inventory of potential tons and grade has had
insufficient exploration to estimate a current mineral resource. The range of tons and
grade could change as additional drilling is completed.
The CuEQ mineral inventory outlined:
• 491 million tons averaging 0.16% CuEQ, using a 0.06% CuEQ cutoff
• 180 million tons averaging 0.28% CuEQ, using a 0.16% CuEQ cutoff
• 136 million tons averaging 0.31% CuEQ, using a 0.20% CuEQ cutoff

The copper only (“Cuppm”) mineral inventory outlined:
• 193 million tons averaging 0.13% Cu, using a 0.06% Cu cutoff
• 44 million tons averaging 0.24% Cu, using a 0.16% Cu cutoff
• 27 million tons averaging 0.28% Cu, using a 0.20% Cu cutoff
These results do not include the ongoing 2022 deep drill hole assays. Which ar e
currently in the assay process.
Mineral Inventory Estimate Process
The inventory was done using GeoSoft® 3D software with these parameters:
• Used all drill assays through 2021 and all historic drill assays (92 holes total)
to assign CuEQ and Cuppm values to voxels.
• 1/d2 calculation to assign CuEQ and Cuppm values to 20 cubic meter volumes
(“Voxels”).
• CuEQ values calculated from Cu, Ag, Au, Mo, Pb, and Zn using CuEQ values
were calculated by for each drill hole assay values for Cu, Ag, Au, Mo, Pb, and
Zn based on metal prices taken from Kitco.com and DailyMetalPrice.com on
July 27, 2022 (Cu-$3.43/lb, Ag -$18.66/oz, Au -$1719.50/oz, Mo -$19.73/lb,
Pb-$0.91/lb, and Zn-$1.41/lb).
• Drill hole spacing varies from 5 feet (1.5 m) to 3700 feet (1128 m).

Buster Hunsaker, Consulting Geologist to Majuba Hill Copper and a member of the
Advisory Board commented: “This mineral potential estimation indicates that results
from the current drilling and future drill holes will lead to a 3x to 5x increase in the
tonnage. Significant thicknesses of higher grades reported in the News Release dated
September 7, 2022, shows that CuEQ values in recent drilling are very encouraging.
Utilizing these results will help guide and focus our drilling to expand mineralization
at Majuba and evaluate the economic potential.”
David Greenway, President and CEO, commented: “I am very encouraged. This global
mineral inventory indicates that Majuba Hill has the potential we expected to grow
into the next large scale copper deposit in the Western United States.”
Quality Assurance/Quality Control ("QA/QC") Measures, Chain of Custody
The Company has implemented a QA/QC program using best industry practices at
the Majuba Hill Project. The samples are transported from the JUBA secure warehouse
or directly from the drill to the ALS Sample Prep Facility in Reno or Elko, Nevada. ALS
then transports the prepared pulps to their analytical lab in Reno, Nevada or
Vancouver, B.C. Soil and rock chip samples are transported by the company directly
to Elko or Reno, Nevada.
Drill core samples are sawn in half lengthwise and one half is placed in labeled cloth
sample bags. All samples are analyzed for copper, gold, silver, and 3 3 other
elements. Gold is determined by ALS method Au-AA23 which is a fire assay with an
AAS finish on a 30 gram split. Copper, silver and the remaining 31 elements are
determined by ALS method ME -ICP61 which is a four acid digestion and ICP -AES
assay. Approximately 5% of the submitted samples are drill duplicates and copper-
gold-porphyry commercial standard reference material pulps. The sample rejects and
remaining pulps will be retrieved from ALS.

About Majuba Hill Copper Corp.
Majuba Hill Copper Corp. is engaged in the identification, review and acquisition of
latter stage copper and copper/ silver/gold assets. This is in direct response to the
growing worldwide demand and lack of supply for precious metals fueled by the Green
New Deal in the US and most other developed nations with similar programs aimed
at addressing climate change. Such programs are heavily reliant on silver, gold and
4
especially copper to produce Electric Vehicles and other renewable power sources, as
well as building infrastructure to provide clean and affordable electricity.
The flagship project is the Majuba Hill copper, silver and gold District located 156
miles outside Reno, Nevada, USA. Management has been mandated to focus on safe,
mining friendly jurisdictions where government regulations are supportive of mining
operations.
