Majuba Hill Copper Reports 2022 Core Results:
Longest Intercepts of Copper Mineralization ever
Drilled at Porphyry Project
VANCOUVER, BC — January 23, 2023 — Majuba Hill Copper Corp. (CSE: JUBA / OTC:
JUBAF / FWB:4NP) (“Majuba Hill Copper” or the “Company”) is pleased to report that
2022 core holes MHB-27 and MHB-28 intersected over 1000 feet (304.8 meters) of
plus 0.25% copper equivalent (“CuEQ”) mineralization at the Majuba Hill Porphyry
Copper Project in Pershing County, Nevada. These are the longest copper mineralized
intercepts ever drilled at Majuba. The mineralized intersections are directly
correlative with porphyry-type vein density, pervasive porphyry-style alteration, and
multiple intrusive events.
Highlights
MHB-27: 1136 ft (346.3 m) @ 0.25% CuEQ starting at 710 ft (216.4 m) including:
• 834 ft (254.2 m) @ 0.31% CuEQ from 750 to 1584 (228.6-482.8 m)
• 119 ft (36.3 m) @0.14% CuEQ from 1727-1846 ft (526.4-562.7m)
MHB-28: 1287 ft (392 m) @ 0.30% CuEQ starting at 245 ft (74.7 m), including:
• 652 ft (198.7 m) @ 0.33% CuEQ from 595 to 1247 ft
• 192 ft (58.5 m) @ 0.21% CuEQ from 1340 to 1532 ft
• 105 ft (32 m) @ 0.18% CuEQ from 1542 to 1647 ft
MHB-29: Intersected granodiorite porphyry at 3403 ft (1037 m). The entire hole is
mineralized with 3607 ft (1099.4 m) @ 0.05% CuEQ from 0 to 3607 ft.
• Strong potassic alteration that is overprinted by pervasive propylitization.
• Zoning within the Majuba Target Zone indicates MHB-29 is southwest of the
main mineralized zone.
• Intersected 26 intervals greater than 0.20% CuEQ
MHB-27, 28, and 29 mineralization characteristics include:
• Supergene enrichment from the surface down to at least 1420 ft (432.8 m)
• Distinct porphyry style “A”, “B”, and “D” type veins in all drill holes
• Trace element geochemistry zoning for molybdenum, zinc, and bismuth.
The 2022 core drilling program focused on the Majuba Target Zone. The goal was to
complete deeper holes and extend the copper mineralization intersected in the 2020
and 2021 drill campaigns. Detailed results are shown in Table 1.
An updated property wide mineral inventory estimate is now underway.
David Greenway, CEO stated, “The tremendous thickness of copper mineralization
confirms that Majuba Hill is a significant porphyry copper discovery in Nevada, one
2
of the top three mining jurisdictions in the world. Copper mineralization from top to
bottom also indicates that we have discovered a deposit which will have an impact
on the copper supply for the world at a time when the world needs long-term, secure
supplies for the future. With our mineral inventory estimate announced September
20th, 2022, showcasing the potential for 1.5 billion pounds of copper equivalent, we
now have these game changing results in hand to expand on that estimate and
ultimately contribute to the development of a NI 43-101 compliant copper resource.”
Cross Section 375879E: Holes MHB-27 and MHB-29 (see map for location)
MHB-27 is mineralized throughout the entire hole with 3500 feet (1066.8 m) @
0.18% CuEQ from 0-3500 feet (0-1066.8 m).
The upper part of the higher-grade mineralization in MHB-27 is enriched down to
1420 feet (432.8 m). Enrichment minerals include azurite, malachite, chalcocite, and
traces of digenite with chalcopyrite/pyrite. A zone of disseminated and fracture
hosted native copper occurs near the deepest parts of the enrichment. The additional
426 feet (129.8 m) of CuEQ mineralization below the enrichment is non-enriched,
primary/hypogene sulfides.

MHB-29 is mineralized throughout the entire hole, containing 0.05% CuEQ from 0 to
3607 feet (0-1099.4 m).
Enrichment is limited to the top 250 feet. The deepest visible native copper and other
enrichment metals occurred at 247 feet. Throughout the hole there are 26 intervals
with greater than 0.2% Cu between 206.5 feet (62.94 m) and 3468 feet (1058.57
m). These mineralized zones have up to 10 feet (3.05 m) @ 0.43% CuEQ.
The long copper mineralization intercepts and the broad spacing of holes MHB-27 and
MHB-29 combined with the molybdenum, zinc, gold, and bismuth assay results
outline distinct mineral zoning. The vector from this zoning indicates that copper
grades are increasing to the northeast. This corridor is outlined by the “2023 Target
Corridor” on the map.

MHB-29 3462-3470 ft:

Copper enrichment in the upper part of hole MHB-29 was limited, however porphyry
style veining is prominent throughout the hole and potassic alteration increased
below 1700 feet. The hole bottomed in granodiorite (3403 to 3607 ft) that is cross -
cut by numerous quartz-pyrite-tourmaline veins plus disseminated and vein
controlled secondary biotite.
Cross Section 4503030N: Hole MHB-28 (see map for location)
MHB-28 is mineralized from top bottom with 1769 feet (539.2 m) @ 0.25% CuEQ
from 0-1769 feet (539.2 m). This includes 1287 feet (392 m) @ 0.30% CuEQ from
245 to 1532 feet (74.7-467 m).

Reverse circul ation drill hole MHB -6 completed in 2020 is close to MHB -28 and
intersected 800 feet @ 0.23% CuEQ from 0-800 feet (0-243.8 m). MHB-28 extended
the copper zone 732 feet ( 223.1 m) deeper and finished in low grade CuEQ
mineralization and strong alteration at the bottom of the hole.
Multiple occurrences of bismuthinite and well developed porphyry veining provide a
vector indicating the copper grade is increasing towards the northeast within the
target corridor on the map.

Copper Equivalent Calculation
Copper equivalent (CuEQ) values were calculated by combining the assay values for
copper, silver, gold, molybdenum, lead, and zinc across the significant copper drill
intercepts for intervals composited to 0.16% Cu and 0.06% Cu.
The Cu, Ag, Au, Mo, Pb, and Zn assay results for each intercept were combined into
the CuEQ value using an interval-weighted calculation based on metal prices taken
from Kitco.com and DailyMetalPrice.com on July 27, 2022.

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 elem ents are
determined by ALS method ME -ICP61 which is a four acid digestion and ICP -AES
assay. Approximately 5% of the submitted samples are 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
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.
