Ryan McDermott, Chief Executive Officer, said, "I am pleased to report the assay results from the Company's 2022 reverse circulation drilling program at Red Star.

"The drilling targeted the boundaries of the magnetic anomalies identified in the 2021 ground magnetics survey, with the aim of further define the extents of those anomalies and to provide depth and geometry to the mineralized subsurface. The results continue to build on our understanding of the Red Star/North Pit area, and further demonstrate the extensive polymetallic mineralization at Empire.

"Holes RS22-02 and RS22-04 show robust metal values consistent with the results of previous drilling in the area. Hole RS22-02 includes 4.99 feet (1.52 m) grading 1.01 g/t of gold, 332 g/t silver, 1.35% copper, 2.18% lead, 1.39% zinc and 156 ppm molybdenum. Hole RS22-04 also returned robust metal values, including 4.99 feet (1.52 m) of 7.59 g/t gold and 0.58% copper.

"While we were only able to complete 268 m of drilling due to the limited availability of the drill rig, the data and results that we collected have added significantly to our understanding of the mineralization and the boundaries of the magnetic anomalies and will aid in future drilling, modeling and ultimately updating of the resource.

"It is important to understand that the drilling results seen thus far in the Red Star area are indicative of higher-grade, narrow vein mineralization which may best lend itself to underground mining methods. Conversely, the longer and lower grade drilling intercepts in the Empire open pit area lend themselves to bulk tonnage, open pit mining methods. The close proximity of both styles of mineralization speaks volumes about the potential size and complexity of the Empire system."

Background

In 2018, exploratory drilling at Red Star, located approximately 330 m northwest of the Empire Mine proposed open pit, intercepted a near-surface high-grade silver and lead zone. In 2019, a maiden inferred resource of 103,000 tonnes containing 173.4 g/t silver, 0.85 g/t gold and 3.85% lead (1.6 million ounces silver equivalent) was reported at Red Star in the Company's NI 43-101 technical report. A ground magnetics survey was conducted in the area during the 2021 field season to help identify the possible location of mineralized structures below the vegetative cover. The survey identified three subsurface magnetic anomalies east of the Red Star discovery outcrop. In response to those findings, seven RC drill holes were completed that year in various locations throughout the anomalous zones. The results of the 2021 RC drilling campaign confirmed magnetite-related mineralisation focused along several northerly trending structures. The Red Star mineralisation appears as discrete zones plunging steeply to the east along the structures mapped in the geophysical survey, similar to the well-understood magnetite zones encountered in the open pit area on the southern end of the project.

The 2022 RC drilling programme targeted the extensions of these structures. This effort was part of a larger plan to gather geochemical data and better understand the boundaries and characteristics of the magnetic anomalies. The geological structures in the area can be challenging to drill because of the highly variable material they contain and the steep topography typical of the area. The geological formations in the area consist of a mix of hard garnet skarn and granite porphyry, as well as softer and more friable material. Due to this variation in material, drilling progress can be slow in order to maintain a high quality of samples.

Assay Quality Control

All RC chips are logged by Konnex personnel at Phoenix's drill core facility located in Mackay, Idaho, USA. The RC chips are split at the drill rig. One half is sent to a commercial laboratory for assaying, and the other half is kept for future reference. A strict QA/QC programme is in place by integrating duplicates, blanks, and certified reference standards into the RC sample sequence.

Notes

Phoenix Copper Limited is a USA focused, base and precious metals emerging producer and exploration company, initially targeting copper and zinc production from an open pit mine.

Phoenix's primary operations are focused near Mackay, Idaho in the Alder Creek mining district, at the 80% owned Empire Mine property, which historically produced copper at grades of up to 8%, as well as gold, silver, zinc and tungsten, from an underground mine. Phoenix updated its economic model in February 2021 to include the processing of all contained metals through a two phased approach.

Since 2017, Phoenix has conducted extensive drilling programmes to define the potential of an open-pit heap leach SX-EW mine. In October 2020, a Preliminary Economic Assessment was completed in accordance with NI 43-101. The 2020 PEA reports the measured and indicated resource at 22.9 million tonnes at an average grade of 0.38% copper, 0.324 g/t gold, 10.3 g/t silver, and 0.19% zinc, with a total of 87,543 tonnes of copper, 238,406 ounces of gold, 7,595,198 ounces of silver, and 43,871 tonnes of zinc.

In addition to Empire, the district includes the historic Horseshoe, White Knob and Blue Bird Mines, past producers of copper, gold, silver, zinc, lead and tungsten from underground mines. A new discovery at Red Star, 330 metres northwest of the Empire Mine proposed open pit, has revealed high grade silver / lead sulphide ore, and from three shallow exploration drill holes a maiden inferred resource of 103,000 tonnes containing 173.4 g/tonne silver, 0.85 g/tonne gold and 3.85% lead (1.6 million ounces silver equivalent) was reported in an NI 43-101 technical report published in May 2019. Additionally, the district includes Navarre Creek, a volcanic hosted precious metals target in a 14.48 sq km area. The Company's total land package at Empire comprises 8,034 acres (32.51 sq kms).

At Empire, it is estimated that less than 1% of the potential ore system has been explored to date and, accordingly, there is significant opportunity to increase the resource through phased exploration. The stated aim of the Company is to fund this phased exploration through free cashflow generated by its initial mine. A Plan of Operations in respect of the initial open pit mine was filed with the relevant regulatory authorities in June 2021.

Phoenix also has two wholly owned cobalt properties on the Idaho Cobalt Belt to the north of Empire. An Earn-In Agreement has been signed with Electra Battery Materials, Toronto, in respect of one of those properties.

Phoenix is listed on London's AIM (PXC), and trades on New York's OTCQX Market (PXCLF and PXCLY (ADRs)). More details on the Company, its assets and its objectives can be found on PXC's website at    https://phoenixcopperlimited.com/
