TORONTO, ONTARIO (January 7, 2026) – TheNewswire – LAURION Mineral Exploration Inc. (TSX-V: LME | OTC: LMEFF | FSE: 5YD) (‘LAURION’ or the ‘Corporation’) is very pleased to report assay results of the first two drill holes from recent diamond drilling at the A-Zone/McLeod/CRK Zone at the Ishkōday Project, located in the Beardmore–Geraldton Greenstone Belt of north-western Ontario, approximately 220 kilometres northeast of Thunder Bay.

The current drill program focuses on the A-Zone/McLeod/CRK Zone, a structurally controlled gold-base metal corridor where historic drilling, surface work, and more recent LAURION drilling demonstrate repeated gold, silver, zinc, and copper mineralization along strike and at depth.

‘These results reinforce what we have been methodically building at Ishkōday — a structurally controlled gold-zinc system with repeated mineralization along a coherent corridor,‘ stated Cynthia Le Sueur Aquin, President and CEO of LAURION. ‘The combination of higher-grade intervals within broader mineralized zones, supported by both historic and recent drilling, gives us confidence that our targeting approach is working as intended. As we continue drilling, our focus remains on understanding continuity, structure, and scale.’

Drill hole LBX25-095 was designed to test a segment of the A-Zone/McLeod/CRK Zone structural corridor supported by proximal historic drill holes 90-41 and 90-49, as well as modern LAURION drill holes LBX20-021 and LBX20-017. Historic drill hole 90-41 intersected multiple gold-bearing intervals at various depths, including 0.55 m grading 3.69 g/t Au and 1.70% Zn, 0.55 m grading 11.88 g/t Au, 8.0 g/t Ag and 8.6% Zn, and deeper intersections including 0.91 m grading 1.63 g/t Au,16.0 g/t Ag, 0.16% Cu and 6.7% Zn, 0.66 m grading 2.12 g/t Au, 14.0 g/t Ag and 10.3% Zn, and 5.36 m grading 0.44 g/t Au, 6.16 g/t Ag and 4.28% Zn (Orient Resources Inc., Sturgeon River Property Diamond Drill Program Report, Claude Larouche, 1990). Nearby historic drill hole 90-49 returned 0.31 m grading 3.87 g/t Au and 1.73 m grading 3.46 g/t Au, 20.36 g/t Ag and 3.72% Zn (Orient Resources Inc., Claude Larouche, 1990). More recent drilling confirmed continuity of mineralization within the same corridor, including 14.08 m grading 0.89 g/t Au in drill hole LBX20-021 and additional gold-silver intervals in LBX20-017 (LAURION press release dated July 28, 2020).

Drill hole LBX25-095 intersected multiple gold-and-zinc-bearing intervals hosted within sheared and altered volcanic rocks consistent with the main A-Zone/McLeod/CRK Zone geological framework.

Reported assay results include 2.60 m grading 1.84 g/t Au from 27.40 to 30.00 m, including 0.60 m grading 7.25 g/t Au, 1.00 m grading 1.02 g/t Au from 45.30 to 46.30 m, and several broader intervals of lower-grade gold with elevated zinc.

A mid-depth mineralized zone returned 3.50 m grading 1.40 g/t Au and 2.30% Zn from 162.50 to 166.00 m, including a higher-grade interval of 0.70 m grading 5.97 g/t Au, 18.4 g/t Ag, 0.22% Cu and 10.8% Zn from 163.05 to 163.75 m.

Deeper in the hole, drilling intersected 4.50 m grading 2.00 g/t Au, 5.75 g/t Ag and 1.22% Zn from 188.00 to 192.50 m, including 0.50 m grading 3.30 g/t Au,17.8 g/t Ag and 6.84% Zn, 2.40 m grading 3.00 g/t Au, and 0.55 m grading 12.15 g/t Au,16.1 g/t Ag and 2.66% Zn.  

Drill hole LBX25-096, located approximately 52 metres east of LBX25-095, was designed to test the eastern continuation of the same structurally controlled mineralized corridor. Targeting for LBX25-096 was informed by proximal drill holes LBX12-006, LBX20-020, and LBX22-089, which intersected gold-bearing mineralization within the same stratigraphic and structural package. Notably, drill hole LBX20-020 returned broad gold-bearing intervals including 6.86 m grading 0.47 g/t Au and 10.84 m grading 0.48 g/t Au, demonstrating mineralized width and continuity and supporting step-out drilling to the east (LAURION press release dated July 28, 2020). Drill hole LBX25-096 subsequently intersected multiple gold-bearing intervals within this corridor, including 3.85 m from 38.70 m to 42.55 m grading 1.92 g/t Au, including a higher-grade interval of 0.55 m from 42.00 m to 42.55 m grading 9.59 g/t Au, and a shallow interval of 1.15 m from 8.35 m to 9.50 m grading 2.14 g/t Au, including 0.50 m from 9.00 m to 9.50 m grading 4.76 g/t Au.

Gold mineralization at Ishkōday occurs within an orogenic gold framework and is commonly accompanied by silver, consistent with orogenic systems globally. In addition, localized enrichment in silver and base metals reflects polymetallic mineralizing events that are overprinted and locally modified by the orogenic gold event. These observations align with structural and geochemical interpretations supporting a multi-phase mineralizing history, as outlined in the Keaton Strongman Report 2024 on the Ishkōday: Ancestral structural controls between Archean epithermal and orogenic gold mineralization.

TABLE Of ASSAYS FOR DRILL HOLES LBX25-095 AND LBX25-096

Mineralization on the A-Zone/McLeod/CRK Zone is interpreted to be controlled by the interaction of north–south-trending quartz-gold extensional veins and northeast–southwest-trending sulphide-rich shear veins. Reactivation of earlier sulphide zones during later deformation, locally associated with magnetite-rich assemblages, provides a structural framework that explains repeated gold enrichment, localized grade enhancement within wider base metal envelopes, and strong strike continuity beneath cover.

The current drilling on the A-Zone/McLeod/CRK Zone has focused on refining LAURION’s understanding of the geometry, continuity, and structural controls of the mineralized system. Ongoing work by the LAURION’s technical team and independent consultants is centred on consolidating historical and modern drilling, validating geological interpretations, and strengthening the 3D structural framework. This work is intended to ensure that any future technical milestones are based on a robust, well-constrained geological model, while preserving strategic flexibility as the Ishkōday Project continues to evolve.

Sampling and QA/QC Protocols

All drill core is transported and stored inside the core facility located at the Ishkōday Project in Greenstone, Ontario. LAURION employs an industry standard system of external standards, blanks and duplicates for all of its sampling, in addition to the QA/QC protocol employed by the laboratory. After logging, core samples were identified and then cut in half along core axis in the same building and then zip tied individually in plastic sample bags with a bar code. Approximately five or six of these individual bags were then stacked into a ‘rice’ white material bag and stored on a skid for final shipment to the laboratory.

All core samples were shipped to the ALS facility in Thunder Bay, Ontario, which were then prepared by ALS Global Geochemistry in Thunder Bay and analyzed by ALS Global Analytical Lab in North Vancouver, British Columbia. Samples are processed by 4-acid digestion and analyzed by fire assay on 50 g pulps and ICP-AES (Inductively Coupled Plasma – Atomic Emission Spectroscopy). Over limit analyses are reprocessed with gravimetric finish.

A total of 5% blanks and 5% standard are inserted randomly within all samples. 5% of the best assay result pulps were sent for re-assays. All QA/QC were verified, and no contamination or bias have been observed. The remaining half of the core, as well as the unsampled core, is stored in temporary core racks at the core logging facility in Beardmore and moved to the core storage facility at the Ishkōday Project.

Note: QA/QC review of standards and duplicates indicates analytical results are reliable. One zinc standard adjacent to a high-grade zinc interval returned elevated values consistent with expected analytical behaviour following high-grade samples.

Heliostar Metals Ltd. (TSXV: HSTR,OTC:HSTXF) (OTCQX: HSTXF) (FSE: RGG1) (‘Heliostar’ or the ‘Company’) today reported unaudited financial results for the three months ended September 30, 2025 (‘Q3 2025’), which corresponds to the second quarter of Heliostar’s fiscal reporting year 2025. Results are presented in US dollars, unless stated.

Heliostar CEO, Charles Funk, commented, ‘In Q3, Heliostar continued to generate strong cash flow from our operating mines. We grew production and strengthened our capital position while significantly reinvesting across the portfolio. In Q3, this included significant drill programs at Ana Paula and La Colorada, economic studies for La Colorada and Ana Paula as well as permissions and preparations to restart mining at San Agustin. Our strong cash balance has allowed us to internally fund this restart. This gives us a clear path to generate cash flow from operations which will fund the ongoing development of Ana Paula with little-to-no equity dilution.’

‘Our recently released PEA for Ana Paula shows that the additional 101,000 ounces per year of production at an all-in sustaining cost of just $1,011/oz will be a significant cash flow generator for Heliostar, supporting growth through the next decade. The cash generated by being a producer in the current gold price environment affords us opportunities to accelerate our plan to become a mid-tier producer with 500,000 ounces per year before the end of the decade.’

Third Quarter 2025 Quarterly Conference Call

Heliostar will host a quarterly conference call on Monday, November 24, 2025, at 2:00 PM, Eastern Time/11:00 AM Pacific Time. The call will provide a corporate update following the release of our financial and operating results for the third quarter of 2025.

Q3 2025 Operational and Financial Highlights

Total gold production of 9,165 gold equivalent ounces (‘GEO’) (8,949 gold ounces) in Q3 2025. Gold production was realized from mining the Junkyard Stockpile at the La Colorada mine, as well as re-leaching the previously stacked ore at the La Colorada and the San Agustin mines. Production year-to-date January – September 2025 (‘YTD’) remains on track to achieve the lower half of the 2025 guidance issued by the Company on February 4, 2025, of 31,000-41,000 GEOs.

Total Cash Cost of $1,500 per GEO produced in Q3 2025. The combined YTD cash cost (see ‘Non-IFRS Measures’) is $1,405 per GEO.

Total AISC of $1,825 per GEO sold in Q3 2025. The increase from Q2 reflects a change in calculation methodology to include corporate General and Administrative (‘G&A’) and stock based compensation costs, expensed exploration incurred in the period, and remove previously-included by-product credits. The higher AISC is also a function of fewer GEOs sold in the period compared to Q2 2025. The consolidated YTD AISC (see ‘Non-IFRS Measures) is $1,799 per GEO sold.

Total Cash Costs and AISC are below the 2025 guidance range due to higher production relative to the budget. The Company anticipates materially higher costs in Q4 due to one-off sustainable capital investment incurred to restart mining from the Corner Area. These expenses are anticipated to return to lower rates in early 2026 at San Agustin.

Mine Operating Earnings of $14.2 million in Q3 2025. The Company continued to report strong results in Q3 2025 with steady operating unit costs and operating margin benefiting from selling into a rising gold market. Mine operating earnings YTD 2025 are $40 million.

Net income attributable to shareholders of $1.3 million, or $0.01 per share, for Q3 2025. Net income of $1.3 million ($0.01 per share) for Q3 2025 compared to a net income attributable to shareholders of $1.9 million ($0.01 per share) for Q2 2025. This was due to the increased exploration expense as drilling activities at Ana Paula ramped up and lower GEO sales volume in the quarter.

Strengthened financial position and liquidity: On September 30, 2025, the Company had cash of $34.6 million and working capital (defined as current assets less current liabilities) of $46.7 million. The cash position decreased compared to Q2 due to the increase in exploration spending. As of September 30, 2025, the Company had 1,688 unsold ounces (worth approx. $6.9M at current spot gold prices) and no debt.

Maintained stable production at La Colorada mine. The mining of new ore restarted at the Junkyard Stockpile in January 2025. Production from the Junkyard Stockpile was steady during Q3 2025, with operating costs as expected, grade in line with the reserve model and ore tonnes reconciling slightly higher than expected. Production YTD 2025 was 13,328 GEOs (12,883 gold ounces). Ore feed from the Junkyard Stockpile is planned to continue into 2026, with other historical stockpiles identified to provide additional material to be crushed and stacked on the leach pad thereafter. Further, subject to receiving certain land access approvals, the Company intends to expand the Veta Madre pit to exploit its 43k ounces of gold reserves. In addition, drilling is ongoing at Veta Madre Plus with the aim of adding this additional Indicated material into a near-term mine plan in short order.

Restart of mining at San Agustin. Preparation work to commence mining is underway at San Agustin from the Corner area following the receipt of all necessary approvals to restart mining in Q3. The Company anticipates stacking first ore in December with production from the Corner starting near year end and continuing into 2027. Recoverable reserves at the Corner are estimated at 44.5k ounces of gold.

Strong economics and continued drilling success at Ana Paula drive additional investment. On November 6, 2025, the Company announced the results of a Preliminary Economic Study (PEA) for Ana Paula. These showed attractive economics at a conservative gold price driven by production of 101koz/yr after ramp up at an average all-in sustaining cost of $1,011/oz. On the back of this positive outcome, the Company has announced its intention to complete the underground decline access to the deposit in 2026. Technical and regulatory programs are being advanced in parallel and will continue through 2026 to complete a bankable feasibility study in early 2027.

Preparation of updated technical reports. The Company announced the results of an updated technical report for the La Colorada Mine on October 17, 2025, and is concluding an updated prefeasibility study (‘PFS’) for the Cerro del Gallo Project. The Company plans to release the results of the Cerro del Gallo PFS in Q4 2025 and continues to advance the Ana Paula Project feasibility study.

Operational and Financial Results

Results are reported for the three months ended September 30, 2025, which corresponds to the second quarter of Heliostar’s fiscal reporting year 2026.

A summary of the Company’s consolidated operational and financial results for the reporting period is presented below:

Operational Review

Consolidated Production and Costs

Q3 2025 was the Company’s fourth reporting period with metals production. The Company had no production in Q3 2024.

Production of 9,165 GEOs (8,949 gold ounces) for Q3 2025 was reported from the La Colorada mine and the San Agustin mine. In late Q2, the El Castillo mine ceased production and reclamation commenced at the start of Q3. The combined YTD 2025 production of 25,642 GEOs (24,988 gold ounces) is consistent with the 2025 guidance issued by the Company. Heliostar is on track to achieve the lower half of the 2025 production guidance of 31,000-41,000 GEOs with the several week delay in being able to restart San Agustin pushing production from that asset into 2026.

The combined cash costs for the producing operations were $1,500 per GEO sold, and the consolidated AISC was $1,825 per GEO sold. The combined cash costs and AISC are currently in line with the 2025 guidance issued by the Company. Full-year results are expected to be within the guidance range of $1,800-$1,950/GEO for Cash Costs and $1,950-$2,100/GEO for AISC.

La Colorada Mine

Operating results for Q3 2025 were as follows:

In January 2025, mining of new ore restarted at the Junkyard Stockpile by the Company, alongside re-leach activities of ore stacked by previous operators.

During the reporting period, the La Colorada mine produced 5,479 GEOs (5,311 gold ounces). Total revenues of $14.7 million were reported from sales of 4,229 GEOs. The increase in production compared to Q2 was driven by higher grades placed on the leach pad and the first full quarter of solution flow from the leach pad after restart of operations. Production from the leach pad has increased steadily throughout the year and continues to meet all expected parameters.

For the reporting period, cash costs were $1,592 per GEO ($1,354 per GEO YTD 2025). AISC was $1,648 per GEO ($1,439 per GEO YTD 2025), on track to be at the lower end or below 2025 AISC guidance of $1,850-$1,975/GEO.

The Company plans to continue mining of the Junkyard Stockpile through 2025 and into 2026, with other historical stockpiles identified to provide additional, continued feed to the crushers thereafter. Further, subject to receiving certain land access approvals, the Company intends to expand the Veta Madre pit to exploit 43k ounces of gold reserve, which will be timed sequentially with the ore feeds from the historical stockpiles. Drilling is ongoing to define the mineralization at Veta Madre Plus, with the aim of bringing it into the near-term mine plan in short order.

Subsequent to the reporting period, Heliostar released the results of an updated technical report for La Colorada showing and increased resource and a lower capital expenditure. This showed a mine with a six-year life producing 286k gold ounces at an AISC of $1,626 per GEO. This resulted in upside case economics of an NPV5% of $243.3M and an IRR of 168.4% at a $3,500/oz gold price. For more details, see the press release here.

San Agustin Mine

Operating results for Q3 2025 were as follows:

In September 2024, the previous owners of San Agustin placed the mine under care and maintenance, with metals production continuing from the re-leaching of leach pads.

During the reporting period, the San Agustin mine produced 3,686 GEOs (3,638 gold ounces). Total revenues of $12.1 million were reported from sales of 3,480 GEOs. Re-leaching performance continued well above expectations in the quarter as a result of enhanced recovery initiatives conducted earlier in the year. Gold production through the first nine months of the year exceeded full-year 2025 guidance for re-leaching from the mine.

For the reporting period, cash costs were $1,389 per GEO ($1,437 per GEO YTD 2025). AISC was $1,587 per GEO ($1,546 per GEO YTD 2025), YTD on track to achieve full year AISC guidance of $1,700-$1,850/GEO.

During the quarter, the Company completed all regulatory requirements to enable the restart of mining at San Agustin from the Corner area (see News Release dated July 22, 2025). Work to commence mining of the Corner Area cut back was undertaken subsequently, including moving road access, a power line and contractor selection. First ore is on track to be stacked on the leach pad in the coming weeks. Initial gold production from this new material is expected to start near year end 2025 and continue into 2027. Recoverable reserves at the Corner are estimated at 44.5k ounces of gold.

Ana Paula Project

Development and Exploration expenditures at the flagship Ana Paula Project were $3.9 million in Q3 2025 ($1.8 million in Q3 2024).

During Q3 2025, the Company progressed its ongoing 15,000 metre drilling program at Ana Paula with the objective of delivering mineral reserves to support a 10-year life of mine in the Feasibility Study planned to be released in 1H 2027. On October 6, 2025, the Company announced results from the infill drill program (including 88.1m metres at 8.82 g/t) and the addition of a third rig. Subsequent to quarter end on November 18, 2025, the Company announced additional infill results of 83.2m of 17.4 g/t and 70.7m of 9.38 g/t. The drill program continues to successfully define wide zones of high grade mineralization.

Subsequent to the reporting period, Heliostar released the results of a Preliminary Economic Study (PEA) for Ana Paula showing strong economics at a conservative gold price. This showed a mine with a nine year life producing 101koz/yr after ramp up at an AISC of $1,011/oz. This resulted in upside case economics of an NPV5% of $1,012M, an IRR of 51.3% and average annual after-tax free cash flow of $168M at a $3,800/oz gold price. For more details, see the press release here.

Cerro del Gallo Project

During Q3 2025, the Company conducted advanced study work towards releasing a prefeasibility study for the Cerro del Gallo project based on information collected by previous owners. This work includes updated resources and reserves based on an updated gold price as well as better definition of transition material and an optimized mining and stacking plan. The results of this study are planned to be released in the coming weeks. All major environmental and other permits will need to be obtained before an investment decision can be considered by the Company.

Funding Overview

In the three months ended September 30, 2025, 5,916,250 warrants and 766,250 stock options were exercised for total proceeds of $1.5 million and 1,299,579 RSUs were converted.

As of September 30, 2025, the Company had no debt.

Change of Year End

The Company has changed its financial year-end from March 31 of each year to December 31 of each year. The next financial year-end of the Company will occur on December 31, 2025, for the nine months then ended.

Non-IFRS Measures. This news release refers to certain financial measures, such as all-in-sustaining costs, which are not measures recognized under IFRS and do not have a standardized meaning prescribed by IFRS. These measures may differ from those made by other companies and, accordingly, may not be comparable to such measures as reported by other companies. These measures have been derived from the Company’s financial statements because the Company believes that they are of assistance in understanding the results of operations and its financial position. Certain additional disclosures for these specified financial measures have been incorporated by reference and can be found in the Company’s MD&A for Q3 2025, available on SEDAR+.

Cash costs. The Company uses cash costs per gold equivalent ounce sold to monitor its operating performance internally. The most directly comparable measure prepared in accordance with IFRS is cost of sales. The Company believes this measure provides investors and analysts with useful information about its underlying cash costs of operations. The Company also believes it is a relevant metric used to understand its operating profitability and ability to generate cash flow. Cash costs are measures developed by metals companies in an effort to provide a comparable standard; however, there can be no assurance that the Company’s reporting of these non-GAAP financial measures are similar to those reported by other mining companies. They are widely reported in the metals mining industry as a benchmark for performance, but do not have a standardized meaning and are disclosed in addition to IFRS measures. Cash costs include production costs, refinery and transportation costs and extraordinary mining duty. Cash costs exclude non-cash depreciation and depletion and site share-based compensation. Production costs include mining, crushing, processing, and direct overhead at the operation sites.

AISC. AISC more fully defines the total costs associated with producing precious metals. The AISC is calculated based on guidelines published by the World Gold Council (WGC), which were first issued in 2013. In light of new accounting standards and to support further consistency of application, the WGC published an updated Guidance Note in 2018. Other companies may calculate this measure differently because of differences in underlying principles and policies applied. Differences may also arise due to a different definition of sustaining versus growth capital. Note that in respect of AISC metrics within the technical reports, because such economics are disclosed at the project level, corporate general and administrative expenses were not included in the AISC calculations. AISC per GEO includes mining, processing, direct overhead, reclamation and sustaining capital.

Vancouver, British Columbia TheNewswire – August 18th, 2025 Prismo Metals Inc. (the ‘ Company ‘) (CSE: PRIZ,OTC:PMOMF) (OTCQB: PMOMF) is pleased to announce that its has engaged Windfall Geotek Inc. to apply its proprietary Windfall AI System to integrate and analyze geophysical data, topography data and drill hole data at Prismo’s Hot Breccia copper project located in Arizona.

Dr. Craig Gibson, Chief Exploration Officer of Prismo Metals commented: ‘The Hot Breccia Project should be an ideal place to apply the Windfall AI System. It lies in the world-famous Arizona copper belt, between several very well understood world-class copper mines including Christmas, Morenci, Ray and Resolution. (Figure 1) Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth.’

Gord Aldcorn, President of Prismo said: ‘Prismo remains committed to advancing its Hot Breccia copper project, located in the heart of the Arizona copper belt. The engagement of Windfall Geotek is consistent with that commitment. Their work will provide valuable information as we continue to hold discussions with potential strategic partners present in the district or wanting to gain a foothold in the district. The goal remains to conduct a minimum of 5,000 meters of drilling. Results from the Windfall Geotek study are expected to be received by the beginning of September.’

Windfall Geotek, located in Montreal, Canada, is a mining and technology services company and a leader in the application of Artificial Intelligence (AI) for mineral exploration since 2005. The Windfall AI System is a state-of-the-art computerized analysis method that uses the latest Artificial Intelligence (Machine Learning) and pattern recognition algorithms to analyze large digital exploration data sets and produce exploration targets.

Historical drilling was carried out at Hot Breccia in the mid to late 1970’s by a Rio Tinto subsidiary intersected high-grade copper mineralization at depths ranging from 640 to 830 meters below the surface in several holes that targeted one of the magnetic highs, believed to be caused by the magnetite skarn that was cut in the holes and that occurs in xenoliths in cross cutting dikes exposed at the surface. Prismo believes those intercepts cut the periphery of the upper portion of a large mineralized system as interpreted from our exploration program.  Historical drill holes cut high grade skarn mineralization including 23 meters with 0.54% Cu at 640 meters depth (hole OC-1), 18 m with 1.4% Cu and 4.65% Zn at 830 meters depth (hole OCC-7), and 7.6 m with 1.73% Cu and 0.11% Zn at 703 meters and 4.6 meters with 1.4% Cu and 0.88% Zn at 716 meters (OCC-8).

Mineralization occurs within a several hundred-meter-thick altered zone hosted in favorable Paleozoic carbonate rocks that underly a sequence of Cretaceous andesitic volcanic rocks.  These carbonates are the same rocks that host the high-grade copper mineralization at Freeport’s nearly Christmas mine.

The historic drilling intersected a blind mineralized intrusion associated with the skarn mineralization, providing an immediate drill target that is believed to be the source of the mineralization at Hot Breccia (Figure 2). Several magnetic highs in the region surrounding the proposed intrusion may also indicated buried skarn mineralization and provide additional exploration targets.

About Hot Breccia

The Hot Breccia property consists of 1,420 hectares in 227 contiguous mining claims located in the world class Arizona Copper Belt between several very well understood world-class copper mines including Morenci, Ray and Resolution (Figure 1). Hot Breccia shows many features in common with these neighboring systems, most prominently a swarm of porphyry dikes and series of breccia pipes containing numerous fragments of well copper-mineralized rocks mixed with fragments of volcanic and sedimentary derived from considerable depth. Prismo performed a ZTEM survey last year that identified a very large conductive anomaly directly beneath the breccia outcrops.

Sampling at the project has shown the presence of copper mineralization associated with polylithic breccia pipes that transported fragments of strongly mineralized carbonate rocks to the surface from depths believed to be 400-1,000 meters. Drilling deep holes is necessary to tap into the source of these mineralized fragments found at surface.

Assay results from historic drill holes are unverified as the core has been destroyed, but information has been gathered from memos, photos and drill logs that contain some, but not all, of the assay results and descriptions.  Technical information from adjacent or nearby properties does not mean nor does it imply that Prismo will obtain similar results from its own properties.

Data on previous drilling and geophysics is historical in nature and has not been verified, is not compliant with NI 43-101 standards and should not be relied upon; the Company is using the information only as a guide to aid in exploration planning.
