Pecoy Copper Adds Third Broad South Breccia Intercept; Northwest Returns

42.3 Metres at 1.01% Cu Near Surface and Expands Mineralized Footprint

PEC26-072 intersects 804.0 metres at 0.34% Cu and 0.08 g/t Au from 24.0 metres, including 485.2 metres at 0.40% Cu

and 0.09 g/t Au; PEC26-067 intersects 209.0 metres at 0.40% Cu from 15.0 metres

VANCOUVER, British Columbia, Sept. 01, 2026 -- Pecoy Copper Corp. (“Pecoy Copper ” or the “Company”) (TSXV: PCU;

FSE: D5E; OTCQB: PCUUF) is pleased to report new assay results from six diamond drill holes, PEC26-067 through PEC26-

072, completed as part of the Company’s planned 35,000-metre 2026 drill program at its 100%-owned Pecoy Copper-Gold-

Molybdenum-Silver Project in southern Peru. The six holes totalled 5,678.3 metres and tested the South Breccia, Northwest,

Centre-of-Pit and North-Central target areas.

Results are led by PEC26-072, which adds a third broad copper-gold intercept at South Breccia. The hole intersected 804.0

metres grading 0.34% Cu, 0.08 g/t Au, 1.19 g/t Ag and 0.007% Mo from 24.0 metres. This includes 485.2 metres grading

0.40% Cu, 0.09 g/t Au, 1.36 g/t Ag and 0.007% Mo from 244.8 metres , including 100.8 metres grading 0.56% Cu and

0.13 g/t Au from 608.5 metres.

PEC26-072 was collared approximately 166 metres west of PEC25-066 and approximately 360 metres west of PEC25-065.

Together with the previously reported PEC25-065 and PEC25-066 results, PEC26-072 provides a third broad South Breccia

intercept and supports the interpretation of lateral continuity and westward expansion potential. Additional drilling and three-

dimensional modelling are required to determine continuity and true thickness between the holes.

Outside the South Breccia, PEC26-067 returned the strongest near-surface copper result in this batch, intersecting 209.0

metres at 0.40% Cu from 15.0 metres. The interval includes 137.0 metres at 0.50% Cu, 42.3 metres at 1.01% Cu and 11.1

metres at 1.90% Cu. Below the existing resource pit shell, a separate deeper interval returned 296.0 metres at 0.24% Cu and

0.009% Mo from 744.0 metres to the end of the hole. The combination of shallow grade and width, together with the separate

deeper interval, makes Northwest a principal follow-up and expansion target.

Drilling Highlights:

• South Breccia – PEC26-072

◦ 804.0 m at 0.34% Cu and 0.08 g/t Au from 24.0 m, incl.;

◦ 485.2 m at 0.40% Cu and 0.09 g/t Au from 244.8 m, incl.;

◦ 100.8 m at 0.56% Cu and 0.13 g/t Au from 608.5 m, incl;

◦ 52.0 m at 0.67% Cu and 0.10 g/t Au from 656.0 m

• Northwest – PEC26-067 returned the strongest near-surface copper result outside South Breccia in this batch:

◦ 209.0 m at 0.40% Cu from 15.0 m, incl.;

◦ 137.0 m at 0.50% Cu from 15.0 m, incl.;

◦ 42.3 m at 1.01% Cu from 33.7 m, incl.;

◦ 11.1 m at 1.90% Cu from 58.0 m.

◦ A separate deeper interval below the historical pit shell returned 296.0 m grading 0.24% Cu and 0.009% Mo from

744.0 m to 1,040.0 m end of hole;

• Centre of the Pit – PEC26-069

◦ 119.0 m at 0.30% Cu from 29.0 m, including 58.1 m at 0.40% Cu and 22.0 m at 0.50% Cu.

• Centre of the Pit – PEC26-071

◦ 101.4 m at 0.34% Cu from 130.0 m, including 52.0 m at 0.42% Cu.

Vincent Metcalfe, President and Chief Executive Officer of Pecoy Copper, commented: “PEC26-072 adds a third broad copper-

gold intercept at South Breccia, which has now delivered broad mineralization from three separate collar locations and

continues to demonstrate expansion potential to the west. Just as importantly, PEC26-067 returned 209 metres at 0.40%

copper from only 15 metres, including 50 metres at 0.91% copper and 11.1 metres at 1.90% copper. That combination of

shallow position, width and grade, together with the separate deeper interval, expands the known mineralized extent at

Northwest and makes it a compelling second priority.

With assay results received to date representing only approximately 20% of our planned 35,000-metre program, we remain at

an early stage and expect the substantial drilling and results ahead to significantly advance our understanding of Pecoy. We

will prioritize the lateral expansion of South Breccia and follow-up drilling at Northwest while integrating the Centre-of-Pit and

North-Central results into our three-dimensional model.”

Note: Reported intervals represent downhole lengths; true thicknesses have not yet been determined. Grades are length-

weighted averages. Internal lower-grade intervals are included. The 0-to-EOH rows are provided solely as whole-hole context

and should not be interpreted as continuous mineralized intersections. Values may not sum exactly due to rounding.

Exploration Interpretation and Next Steps

The six holes tested several areas across Pecoy, with the objective of expanding South Breccia, identifying additional near-

surface copper mineralization, deeper mineralized packages and improving the Company’s understanding of the broader

system. The results reinforce South Breccia and establish Northwest as leading follow-up priorities, while providing additional

mineralized intercepts in the Centre-of-Pit and North-Central areas.

South Breccia – PEC26-072

PEC26-072 intersected 804.0 metres grading 0.34% Cu and 0.08 g/t Au from 24.0 metres, including 485.2 metres grading

0.40% Cu and 0.09 g/t Au and 100.8 metres grading 0.56% Cu and 0.13 g/t Au.

The hole was collared approximately 166 metres west of PEC25-066 and adds a third broad copper-gold intercept across

South Breccia. Together, PEC25-065, PEC25-066 and PEC26-072 returned broad copper-gold intervals at three separate collar

locations across South Breccia, supporting the interpretation of lateral continuity and identifying the westward direction as a

priority for further testing.

Geological logging records extensive alteration, veining, sulphide mineralization and multiple phases of brecciation, consistent

with a large hydrothermal system. Together with the assay results, these observations provide an important new point for

evaluating South Breccia’s scale, geometry and western extent.

Additional drilling and three-dimensional modelling will be required to determine continuity and true thickness between the

three holes.

Northwest – PEC26-067

PEC26-067 returned the strongest near-surface copper result outside South Breccia in this batch: 209.0 metres at 0.40% Cu

from 15.0 metres, including 137.0 metres at 0.50% Cu, 50.0 metres at 0.91% Cu and 11.1 metres at 1.90% Cu. A separate

deeper interval returned 296.0 metres at 0.24% Cu and 0.009% Mo from 744.0 metres to the end of the 1,040.0-metre hole.

Together, the shallow and deeper intervals extend known mineralization at Northwest from near surface and separately well

below the historical resource pit shell. These results materially increase the exploration significance of Northwest and

establish a clear opportunity for lateral expansion. Follow-up drilling will test the mineralization along strike and across the

target while defining its geometry and continuity.

North-Central – PEC26-070

PEC26-070 returned 345.0 metres grading 0.25% Cu from 424.0 metres, including 194.65 metres grading 0.30% Cu and 83.0

metres grading 0.34% Cu. Logging identified alteration, veining, sulphide mineralization and brecciation throughout the

mineralized interval.

The result confirms a broad mineralized interval at depth in the less-explored North-Central area. Further work will evaluate

whether it represents an extension of an existing zone or a separate mineralized domain.

Centre-of-Pit and Other Results – PEC26-068, PEC26-069 and PEC26-071

PEC26-069 and PEC26-071 returned near-surface copper intervals at separate locations within the Centre-of-Pit area, while

PEC26-068 returned 170.1 metres at 0.25% Cu from 303.9 metres and encountered hydrothermal brecciation near the bottom

of the hole. These results provide additional pierce points for three-dimensional modelling and target vectoring. Further drilling

is required to determine whether the intervals belong to continuous domains or separate structurally controlled zones.

Logging across PEC26-068 through PEC26-071 records altered, veined and locally brecciated intrusive rocks associated with

sulphide mineralization. These geological observations support a hydrothermal origin and help refine follow-up targeting, but do

not, by themselves, demonstrate a geological connection between target areas.

Several of the reported intervals occur within or adjacent to areas previously represented as lower-grade, peripheral or

unestimated in the historical resource model. If additional drilling demonstrates sufficient continuity, these areas may provide

opportunities for future resource growth and improved pit geometry.

Overall Exploration Implications

The results provide three clear priorities for the next phase of work:

1. Continue evaluating the scale and lateral extension of the South Breccia, where three widely spaced holes have now

returned broad copper-gold intercepts.

2. Follow up Northwest, where PEC26-067 encountered strong copper mineralization beginning near surface together with

a separate mineralized interval at depth.

3. Use the results from PEC26-068 through PEC26-071 to refine the geological model and assess the potential for

additional near-surface and deeper mineralized zones across the broader Pecoy system.

The six holes show that copper mineralization occurs across multiple target areas. The results do not establish that the

separate target areas form one continuous mineralized body. They strengthen South Breccia, establish a compelling second

priority in the Northwest sector and provide additional targets for future geological and resource evaluation across Pecoy.

Broad Copper Composites for Geological Context

Each of the six holes contains at least one broad sample-boundary composite with an unrounded length-weighted copper

grade of at least 0.20% Cu. These contextual composites demonstrate the broad distribution of copper mineralization at the

tested locations. They do not establish continuity between holes, inclusion within the current mineral resource or economic

viability.

Exploration Productivity and 2026 Program

Based on the latest drill tracker, over 16,000 metres have been drilled since the current campaign began, with 16 holes

completed and three additional holes in progress. Results reported to date provide new geological and assay information

across the South Breccia, Northwest, Centre-of-Pit and North-Central target areas. The Company continues to target

approximately 35,000 metres of drilling at Pecoy in 2026.

Pecoy Project Highlights

• Large copper system: with an inferred resource of 865 Mt at 0.34% Cu (~6.5 billion pounds contained copper), plus

associated gold, molybdenum and silver credits

• Multiple target areas: South Breccia, Northwest, Centre of the Pit, North-Central and additional targets across the

broader Pecoy property.

• Low-elevation location: approximately 1,650 metres above sea level with year-round road access and proximity to

power, highways and the Pacific coast.

• Favourable topography at Pecoy Hill, with extensive mineralization expressed at surface and consistent with potential

open-pit style geometry

• Additional district-scale upside at Tororume (~8 km north), where all nine historical drill holes intersected mineralization

• Large 2026 program: approximately 35,000 metres planned at Pecoy, compared with approximately 49,000 metres of

historical drilling before the current campaign.

Qualified Persons and Technical Notes

The scientific and technical information in this news release has been reviewed and approved by Vincent Cardin-Tremblay,

P.Geo., current Chief Geological Officer of Pecoy Copper, a Qualified Person as defined by National Instrument 43-101 –

Standards of Disclosure for Mineral Projects (“NI 43-101”).

The Qualified Person verified the data disclosed in this news release by reviewing the final laboratory assay workbooks and

certificates, drillhole collar and downhole-survey data, sampling and analytical procedures, and QA/QC results. No limitations

were imposed on the verification process.

Diamond drill core from the Pecoy Project was logged and sampled at the Company’s secure core facility at site by Company

personnel. Drill core was sawn in half, with one half retained for reference and the other half sampled at nominal intervals of up

to 2 metres, with sample boundaries adjusted to respect geological contacts. Core diameter varied between HQ and NQ

depending on depth.

Samples were bagged, sealed, and transported by commercial carrier to the Bureau Veritas preparation laboratory in

Arequipa, Peru, where samples were crushed and a 250 g split was pulverized to 85% passing 75 micrometres (200 mesh).

Prepared pulps were then sent to the Bureau Veritas assay laboratory in Lima, Peru. Bureau Veritas is an ISO-accredited

laboratory and is independent of the Company.

Gold analyses were performed using fire assay fusion with ICP-OES finish on a 30 g sample (FA330). Samples returning gold

values greater than 10 g/t Au were re-analyzed using fire assay with gravimetric finish (FA530). Copper and silver were

analyzed by ICP-OES/MS following a four-acid digestion as part of a 45-element multi-element suite (4A200). Samples

returning values over the upper detection limit (Au, Ag, Cu, Zn, Mo, Pb) were re-analyzed using four-acid digestion with AAS

finish (MA402).

A comprehensive Quality Assurance and Quality Control (QA/QC) program was implemented as part of the sampling and

analysis procedures. Certified reference materials, blanks, and duplicate samples (field, preparation, and analytical duplicates)

were inserted into the sample stream at regular intervals, representing approximately 15% of the total samples submitted. No

significant QA/QC issues were identified during the analysis, and the results are considered reliable for reporting purposes.

About Pecoy Copper

Pecoy Copper is advancing the 9,975-hectare Pecoy Copper-Gold-Molybdenum-Silver Project, a large, undeveloped porphyry

system located in southern Peru’s Arequipa region, within one of the world’s most prolific copper belts. The Pecoy deposit

hosts a current inferred mineral resource of 865 million tonnes at 0.34% Cu, with significant associated gold, molybdenum,

and silver credits.

Prior to the Company’s 2026 drill program, less than 49,000 metres of historical drilling had been completed at Pecoy, defining

a broad and continuous mineralized system with potential for expansion along strike and at depth. The project benefits from its

favourable elevation of approximately 1,650 metres above sea level, providing year-round access and reduced operating

complexity compared to many high-altitude Andean deposits.

Strategically located near the Pacific coast, Pecoy enjoys excellent infrastructure, with close proximity to highways, power

lines, and water sources, and good access to the deep-water ports of Matarani (approximately 240 km southwest) and Ilo.

This infrastructure advantage positions Pecoy Copper to advance the project efficiently from exploration toward future

development within one of the world’s most established and mining-friendly jurisdictions.
