Discovery Silver Corp. (TSX: DSV) (OTCQX: DSVSF) reported results from ongoing exploration at the Company’s Porcupine Operations, including Hoyle Pond Mine, Borden Mine and Pamour Mine, as well as at the Dome and TVZ advanced stage growth projects and regional exploration targets. The results include assays from a combined total of 143 holes1 (44,740 m), completed between Q4 2025 and Q1 2026.

Tony Makuch, Discovery’s CEO, commented: “We continue to get excellent results from our ongoing aggressive exploration program at Porcupine. Today’s results include additional success with resource conversion and extension drilling at Hoyle Pond, Borden and Pamour, encouraging results at new targets at or near these operations, and favourable results at our near-term growth projects and key regional targets. At Hoyle Pond, we continued to extend the S Zone to depth, recorded the highest-grade intersection to date at TVZ, and continued to demonstrate TVZ’s attractive depth potential, and also had very encouraging results from the Owl Creek and 750 Zone regional targets located along the Hoyle Pond belt.

“Turning to Borden, we extended mineralization down plunge and to the east in the Main Zone and also recorded encouraging results from the East Lower Zone, a parallel structure to the main mining trend. These latest results, along with wide-spaced surface drilling, provide us with a high level of confidence in the potential for significant resource growth as drilling continues.

“At Pamour, we achieve excellent results from ongoing resource conversion and expansion drilling along the three phases of the current pit design. We also generated positive results from drilling at Pamour West, highlighting the potential for new resources west of the current Pamour operations. In addition, we were particularly encouraged by drill results from a large, untested gap in previous drilling at the North Contact Zone, located along a major east – west trending volcanic sedimentary contact directly north of the phase 2 pit.

“Finally, we reported additional positive results from confirmation and extension drilling at Dome in the southwest and northeast portions of the property. Dome is a key potential value generator for Discovery, with an 11.0 million ounce inferred resource, an existing open pit and the Dome Mill located directly adjacent to the pit. Drilling in the northeast part demonstrated a close correlation of geology, with new drilling including similar or better grades and widths compared to historic holes. Drilling in the southwest portion of the property identified new areas of mineralization at shallow depths from surface. With the success we are having, and the additional drilling that is planned, we remain on track to release an updated mineral resource at Dome late this year.”

Hoyle Pond Mine

Drilling at the Hoyle Pond Mine included a total of eight holes (2,814.0 m) to test the Lower S Zone. Of the holes drilled, three holes (237 m) were abandoned due to drilling challenges or excessive deviation from the target.

The Hoyle Pond Mine is located approximately 20 km northeast of Timmins and is situated in the east portion of the Hoyle Pond volcanic belt adjacent to a major northeast trending flexure and the 1060 fault. Mineralization at the mine occurs in multiple zones of quartz veining between surface and a depth of 2,000 m along the trend of the main flexure. The S Zone, which is the main focus of the current drill program, lies in the lower east portion of the mine, just east of the 1060 fault (Figure 1).

The new drilling was designed to test the lower limits of the zone below the 2,200 level and continued to demonstrate very positive results including: 13.52 gpt over 9.1m in hole 27700AM; 45.77 gpt over 4.1m, including 133.00 gpt over 0.6m in hole 27713B; 5.69 gpt over 8.5m, including 20.40 gpt over 0.5m and including 45.70 gpt over 0.5m in hole 27712; and 16.70 gpt over 0.6m in hole 27677M (Figure 2).

The program is continuing at the mine with five drills including two at the Lower S Zone, two at the XMS Zone and one at the NMV/UM4 zones. Work is also ongoing to prepare several new locations in the mid-mine area for drilling which will start later in the second quarter of 2026.

TVZ Project

Drilling at the TVZ Project included a total of 17 holes (5,803 m) from the 1210 level and 1680 level exploration drifts to confirm and expand the TVZ Zone.

TVZ is a significant zone of gold mineralization located between the 800 and 1800 m levels in the southeast portion of the Hoyle Pond Mine (Figure 3).

Geologically, TVZ lies in the Porcupine sediments south of the Hoyle Pond volcanic belt, just east of the 1060 fault. Gold mineralization is closely associated with a northeast trending, steeply dipping shear zone (TVZ2 Zone) with local splay veins, which plunges moderately to the northeast. The bulk of the mineralization identified to date occurs within a panel measuring approximately 600 m long by 200 m in height, extending from the 850 level to just below the 1410 level, with the best grades typically having a strong correlation with increased amounts of quartz veining, pyrite and arsenopyrite.

Past work at the project includes 437 holes (172,319 m) of wide-spaced drilling from three main platforms on the 900, 1210 and 1410 levels, as well as limited development, mapping, chip sampling and metallurgical test work on the 1210 level. Results from the drilling, mapping and chip sampling have been positive and indicate multiple holes with grades exceeding 5.00 gpt over widths of 5 to 10 m. The results also indicate positive results from the two deepest holes to test the zone to date, holes 21009 and 21094, with returned values of 6.29 gpt over 5.3 m and 4.98 gpt over 4.0 m, respectively, between the 1550 and 1610 levels. As a result, the potential to extend the zone to greater depths is considered excellent.

Results of the past metallurgical work indicate a strong correlation of gold with arsenopyrite and variable recoveries, but with the potential for improvement using enhanced processing.

The current work program is designed to infill and expand the TVZ Zone, with drilling ongoing from the historic drill platforms, in preparation for an initial NI 43-101 mineral resource in late 2026.

Drilling from the 1210 level included eight holes (2,595 m) which were drilled across the main zones in a southeasterly direction to evaluate the upper portion of the target model. Results of the program were very positive (Figure 4) and included multiple significant assays from the TVZ1 and TVZ2 zones, which mark the north and south limits of the zone, as well as from splay veins located in the area between.

Significant intercepts from the TVZ1 include: 72.46 gpt over 1.7m, including 770.00 gpt over 0.2m in hole 27886; 6.14 gpt over 2.8m in hole 27887; 27.91 gpt over 0.9m in hole 27885; and 6.39 gpt over 1.2m in hole 27884. All four holes were drilled into an untested gap just above the 1210 level. The new intercept from hole 27886 is from the centre of the untested gap and is the highest-grade intercept obtained from this zone to date. Hole 27885 tested 50 m below hole 27886, hole 27887 tested 60 m to the southwest and, hole 27884 tested 50 m to the northeast.

Significant intercepts from the TVZ2 include: 4.39 gpt over 9.2 m in hole 27881; 4.23 gpt over 55.0m, including 10.83 gpt over 4.0m, and including 5.39 gpt over 27.0m in hole 27883; 3.27 gpt over 13.8m, including 5.24 gpt over 5.0m and 3.18 gpt over 9.0m in hole 27886; 3.87 gpt over 25.0m, including 6.41 gpt over 11.0m in hole 27966; and 3.42 gpt over 33.5m, including 4.40 gpt over 8.1m and including 5.18 gpt over 9.1m in hole 27965. Holes 27881 and 27886 targeted the east-central portion of the zone below the 1210 level and 35 m above the previously reported result of 3.90 gpt over 7.5m from hole 27882 (see press release dated February 10, 2026). Hole 27883 targeted the zone 85 m to the northeast of 27882 and holes 27965 and 27966 targeted approximately 170 m to the southwest.

Among significant intercepts from the splay veins were 4.36 gpt over 22.0m, including 13.33gpt over 4.4m in hole 27881; 8.38 gpt over 1.8m and 4.48 gpt over 11.6m, including 6.13 gpt over 7.4m, in hole 27965; and 3.57 gpt over 14.0m, including 7.81 gpt over 4.1m and 4.17 gpt over 11.5m, in hole 27966. The new intercept in hole 27881 lies 25 m directly above the previously reported result of 4.0 gpt over 30.1 m from hole 27982 (see press release dated February, 10 2026) and the intercepts in holes 27965 and 27966 are located approximately 80 m to the west.

Drilling on the 1680 level included nine new holes (3,208 m) which were drilled in a southeasterly direction to test near the lower limits of previous drilling on the TVZ2. Significant results include: 4.32 gpt over 19.0m, including 5.82 gpt over 9.0m and 5.60 gpt over 3.5m, in hole 27854; 4.24 gpt over 10.2m in hole 27856; and 3.80gpt over 10.2m, including 4.73 gpt over 6.0m in hole 27852, which intersected the TVZ2 vein near the 1600 level between previously reported values of 6.29 gpt over 5.3m and 4.98 gpt over 4.0m in holes 21094 and 21009 (see press release dated February 10, 2026).

Drilling at TVZ is ongoing with two drills operating on the 1210 level and one drill on the 1410 level. Drilling on the 1210 level is primarily focused on infilling and extending mineralization proximal to historic drilling, while drilling on the 1410 level continues to test the projected down plunge extension of the TVZ Zone.

Owl Creek

Drilling at the Owl Creek Project included a total of 12 holes (4,592.2 m) to confirm and expand mineralization near the former Owl Creek open pit as well as at the 750 Zone (Figure 5). Of the holes drilled, three holes (155 m) were abandoned due to excessive deviation.

The Owl Creek open pit is located approximately 1.5 kilometres west of the Hoyle Pond Ramp Portal and along the south side of the Hoyle Pond belt near the contact between metasedimentary and metavolcanic rocks. The pit, as well as two underground ramps below it, were developed by Falconbridge Gold in the 1980’s and were utilized to recover approximately 237,000 ounces of gold at an average grade of 3.75 gpt. The 750 Zone is located approximately 700 m to the east of the Owl Creek pit and consists of a broad zone of mineralization located between surface and the 200 m level, which is defined by historic drilling from both from surface and the underground ramp.

Drilling at the Owl Creek Zone included eight holes (3954.2 m) designed to confirm and expand mineralization identified in both historic holes and previously reported holes (see Discovery Press Release dated November 6, 2025), with results including multiple significant intercepts between surface and the 650 m level.

Significant results include: 4.11 gpt over 30.0m, including 9.04 gpt over 3.0m, 7.17 gpt over 3.0m and 5.24 gpt over 10.1m, in hole OC26-029A; 7.34 gpt over 1.4m, 2.38 gpt over 35.5m, including 4.97 gpt over 2.1m and 6.05 gpt over 3.2m in hole OC26-035; 4.13 gpt over 13.8m, including 7.53 gpt over 7.0m, in hole OC26-37A; and 1.84 gpt over 11.2m, including 2.93 gpt over 3.0m and 4.54 gpt over 2.2m, in hole OC26-028A (Table 3).

Holes OC26-029A, OC26-035 and OC26-37A were drilled to infill untested gaps in the east portion of the deposit between the 275 and 375 m levels, while hole OC26-28A was drilled near the west limits of current drilling near the 400 level.

Drilling at the 750 Zone included one new hole (483.0 m) designed to confirm and expand mineralization near the 250 m level, which is at the lower limits of historic drilling. Results include: 5.76 gpt over 4.5m, 2.57 gpt over 8.9m and 1.62 gpt over 3.3m in hole OC25-027.

While the review and interpretation of drilling is still in progress, the new results at both Owl Creek and the 750 Zone are considered to be very positive. Holes at Owl Creek extend the overall footprint of the deposit to over 200 m and highlight a wide, high grade core of mineralization near the east-central portion of the pit, which starts at less than 100 m from surface. Holes at the 750 Zone highlight a new potential area for resource growth.

The program is continuing with two drills that will continue to focus on infill and extension of mineralization at both the Owl Creek and the 750 Zones. Work is also in progress to review potential new drill targets along the Hoyle Pond – Owl Creek Trend, such as the historic 350 Zone, which is located 500 m to the east of the 750 Zone and is partially developed, with a ramp connecting it to the Hoyle Pond Mine near the main ramp portal.

Borden Mine

Drilling at the Borden Mine included a total of 24 holes (6,585 m) to convert and expand resources in the Main Zone and East Lower Zone (“ELZ”) near the northeast limits of inferred resources (Figures 6, 7 and 8).

The Borden Mine is located approximately 190 km southwest of the Dome Mill, near Chapleau and in the south portion of the Borden Lake Greenstone Belt. The Main Zone is an east-west trending structure located along the east – west trending Genesis Deformation Zone  adjacent to a major contact between felsic gneiss and amphibolite. Work to date has traced the zone for a strike length of over 1.7 km along strike and indicates the zone is closely associated with quartz veining, biotite-garnet alteration and pyrite. The ELZ is a parallel trending, and less explored, structure located approximately 500 m to the west of the Main Zone where recent work indicates potential for significant upside.

Drilling at the Main Zone included 17 holes (5,177 m) completed from cut outs located in the east portion of the 585-exploration drift, situated in the hanging wall of the zone. The results of the drilling continued to demonstrate extremely positive results.

Significant results include: 8.30 gpt over 10.2m, including 11.72 gpt over 3.9m, in 585-00269; 6.51 gpt over 11.3m, including 8.07 gpt over 4.3m, in 585-00268; 4.85 gpt over 14.2m, including 6.74 gpt over 7.4m, in 585-00267; and 5.30 gpt over 13.0m, including 7.47 gpt over 6.1m, in hole 585-00266, which were drilled to test the east side of the zone and extend the east limit of defined mineralization by a minimum of 50 meters to the east (Table 4).

Additional highlights include; 18.85 gpt over 3.1m, 4.42 gpt over 16.6m, including 7.39 gpt over 6.3m, in hole 585-00147; 10.04 gpt over 13.7m, including 21.01 gpt over 3.8m, in hole 585-00149; 7.14 gpt over 12.3m, including 9.40 gpt over 5.2m, in hole 585-00151; 5.54 gpt over 12.6m, including 12.12 gpt over 4.5m, in hole 585-00132; 5.21 gpt over 13.5m, including 7.46 gpt over 5.1m, in hole 585-00229; and 9.39 gpt over 12.9m, including 11.32 gpt over 10.1m, in hole 585-00153, which were drilled in the down plunge extension of the current inferred resource, and which extend the zone by a minimum of 50 to 75 m.

Drilling at the ELZ included seven holes (1,408 m) completed from two drill bays located on the 585 level to confirm and evaluate expansion potential near the lower limits of the zone. Significant results include: 6.24 gpt over 15.7m, including 7.68 gpt over 7.9m, in hole 585-00285; 6.87 gpt over 21.0m, including 9.08 gpt over 9.1m, in hole 585-00284; 7.13 gpt over 10.9m, including 10.79 gpt over 5.8m, in hole 585-00282; and 5.35 gpt over 15.1m, including 8.60 gpt over 6.5m, in hole 585-00287, which are located 50 to 75 m down dip of the current indicated resource. The zone remains open to depth.
,

Review of the above drill results indicate that both the Main Zone and ELZ are trending close to plan and with grades and widths that are similar to, or better than, the current resource model. These results, along with wide-spaced surface drilling down plunge of the Main Zone, continue to provide confidence in the potential for further resource growth as drilling continues.

The program is continuing with four underground drills working to convert and extend resources. Work is also continuing to advance the 585-exploration drift to the northeast to provide new drill platforms for future drilling. Two surface drills are also operating in the area northeast of the Main Zone.

 Pamour

Drilling at the Pamour Mine area included a total of 67 holes (20,121 m) to test areas within and surrounding the large open-pit resource at the property, which includes 64.8 million tonnes grading 1.30 gpt (2.70 million ounces) in the Indicated category and 23.3 million tonnes grading 1.34 gpt (1.00 million ounces) in the Inferred category (Figure 9).

The Pamour Mine is located approximately 20 km east of Timmins on the north side of the Destor Porcupine Fault Zone and straddles the unconformity between Tisdale Group volcanics and Timiskaming sediments. Mineralization at the mine is closely associated with quartz veining, which can occur in single veins, vein arrays, stockworks as well as pyrite both along the unconformity and in volcanics to the north.

The holes drilled were focused on three main areas including the Pamour pit, North Contact Zone and Pamour West.

Drilling at the Pamour Pit included 56 holes (15,918 m) and was focused on the east and west portions of the pit. The drilling represents a continuation of a program which commenced in the second quarter of 2025 to convert and extend resources in preparation for a new resource update later in 2026.

Significant results from drilling in the central portion of the pit include: 1.15 gpt over 109.0m, including 14.10 gpt over 0.5m, in hole PAM25-0109; 5.25 gpt over 19.7m, including 169.00 gpt over 0.7m, 2.42 gpt over 22.3m, 1.58 gpt over 30.0m and 0.75 gpt over 42.9m in hole PAM25-0116; 2.29 gpt over 45.3m in hole PAM25-0055; and 1.36 gpt over 54.1m, including 46.70 gpt over 0.5m, and 1.25 gpt over 12.4m, including 7.05 gpt over 1.0m, in hole PAM25-0094 (Table 5).

Significant results from drilling to the east, which overlie the Phase 3 pit, include: 1.94 gpt over 28.5m, 2.44 gpt over 9.2m, 0.76 gpt over 20.8m and 4.37 gpt over 8.0m in hole PAM25-0100LR; 1.78 gpt over 5.0m, 4.54 gpt over 12.6m, 0.84 gpt over 16.0m and 0.87 gpt over 38.5m in hole PAM26-0132; 2.95 gpt over 12.6m and 1.00 gpt over 16.5m in hole PAM26-0186; and 1.66 gpt over 31.1m in hole PAM26-0183LR.

Significant results from drilling to the west, which overlie the phase 2 pit, include: 1.35 gpt over 65.1m in hole PAM26-0168; 2.34 gpt over 18.3m in hole PAM26-0169; 1.34 gpt over 56.1m, 1.09 gpt over 10.2m and 0.69 gpt over 36.1m in hole PAM26-0153; and 1.29 gpt over 41.4m, 1.30 gpt over 6.0m and 1.04 gpt over 34.2m in hole PAM26-0153.

Drilling at Pamour West included six holes (2,085 m) to confirm and expand mineralization surrounding the historic underground mine and open pit. Among significant results were 1.18 gpt over 7.0m, 0.97 gpt over 11.2m, 6.84 gpt over 7.5m, 1.84 gpt over 6.0m and 1.77 gpt over 5.9m in hole PAM26-0167; and 5.17 gpt over 3.2m, 0.88 gpt over 10.0m, 3.01 gpt over 3.8m, 9.35 gpt over 3.7m and 2.49 gpt over 7.7m, including 51.10 gpt over 0.3m, in hole PAM26-0161.

Drilling at the North Contact Zone included five holes (2,119 m) and targeted mineralization on a major east – west trending volcanic sedimentary contact located directly north of the phase 2 pit and into an untested gap in drilling between historic holes 600 m to the east and 800 m to the west. Significant results from the new drilling include: 2.52 gpt over 20.0 m and 0.78 gpt over 35.5m in hole PAM26-0170; 24.11 gpt over 8.0m, including 596.00 gpt over 0.3m, and 1.45 gpt over 23.1m in hole PAM26-0165; and 1.53 gpt over 3.5m, 0.70 gpt over 19.6m and 1.70 gpt over 23.9m, including 20.70 gpt over 1.0m, in hole PAM26-0180. Significant results from historic holes to the west include 1.95 gpt over 23.0m and 2.69 gpt over 15.6m in hole 19093; 1.45 gpt over 14.8m, 40.40 gpt over 3.3m and 7.30 gpt over 6.2m in hole 19039. Significant results from holes to the east include 3.37 gpt over 36.1m in hole 19150 and 2.85gpt over 37.4m in hole 19144.

Dome Mine Project

Drilling at Dome included a total of 15 holes (4,825 m) being completed (Figure 10), with one hole (18 m) being abandoned due to excessive deviation from the target.

Dome is among the largest historic gold producers in Canada, with total production of 16.7 million ounces from both underground and open pit sources between 1910 and 2017.

Geologically, the mine is located on the south limb of the Porcupine Syncline and is just north of the Destor Porcupine Fault, with mineralization in multiple zones extending from surface to a depth of approximately 1,600 m.

The current mineral resource at Dome includes 222.3 million tonnes with an average grade of 1.49 gpt for a total of 11.0 million ounces in the Inferred category. The resource assumes a large-scale, open-pit concept to expand the historic pit along strike and to depth.

The current drill program is being completed in preparation for a new mineral resource estimate and involves drilling in areas surrounding and below the historic pit. The work program also includes further evaluations of data and mineralization models to upgrade portions of the resource to the Indicated resource category, and also to evaluate the potential for future underground mining at Dome.

The new drilling was focused on infilling gaps in information and confirmation of historic drill holes in the southwest and northeast portions of the property and obtained very positive results.

Drilling in the northeast portion of the property included 10 holes (3,765.4 m) to evaluate mineralization along the northeast extension of the Dome Fault near the lower portion of the current resource pit. The holes were drilled on four cross sections spaced at 10 to 15 m centers and oriented in a northwesterly direction to cross the main trends of mineralization. Results from the drilling were very successful and indicated close correlation of geology, with similar or better grades and widths for new vs historic holes, which were drilled prior to 1970. Significant results from the drilling include: 1.13 gpt over 29.7m in hole DOM25-037; 1.01 gpt over 20.0m and 4.20 gpt over 3.0m in hole DOM26-001; 1.19 gpt over 28.9m in hole DOM26-003; and 3.16 gpt over 15.0m in hole DOM26-004. These new results are in addition to the previously released results of 2.50 gpt over 12.4m and 3.97 gpt over 6.0m in hole DOM25-030 in the same target area (see press release dated February 10, 2026 – Table 6).

Drilling in the southwest portion of the property included four exploration holes (1041.5 m) completed as part of the ongoing evaluation of new targets to the south of the open pit resource. These holes were successful in continuing to identify new mineralization at shallow depths from surface. Significant results from this area include: 2.77 gpt over 10.9m and 1.21 gpt over 11.3m in hole DOM25-020; 0.60 gpt over 8.2m in hole DOM25-018; and 3.11 gpt over 3.5m in hole DOM25-017.The intercept from DOM25-020 is located approximately 60 m southwest of the main pit, while the intercepts from holes DOM25-018 and DOM25-17 were 60m and 120m further to the north.

Drilling at the project is continuing with two drills, one located in the southwest portion of the historic open pit and the other on the north side. Work is also continuing to evaluate additional drill targets to the north, south and west sides of the pit. Considering results and progress to date, the project remains on track for the planned resource update in late 2026.
