M&I Conversion Program Drilling Continues to Expand and Confirm Continuity of High-Grade Gold and Silver Mineralization in the Shallowest Portion of the M&I Conversion Area

HIGHLIGHTS:

  • TXC25-138 returned multiple broad zones of high-grade silver and gold mineralization spanning from 230.4 metres to 241.86 metres down hole, including:
    • 4.24 metres grading 700 grams per tonne (g/t) silver equivalent (AgEq) (Ag/Au ratio 90:1) (378.5 g/t silver (Ag) and 3.57 g/t gold (Au)) from 230 metres down hole, including 0.31 metres grading 3,182 g/t AgEq (1,805.0 g/t Ag and 15.27 g/t Au); and
    • 5.18 metres grading 556 gt/ AgEq (328.2 g/t Ag and 2.53 g/t Au) from 236.68 metres, which included intervals of 3,340 g/t AgEq (1,987 g/t Ag and15.0 g/t Au) over 0.31 metres and 1,714 g/t AgEq (1,037.0 g/t Ag and 7.51 g/t Au) over 0.61 metres respectively.
  • There are ten drillholes with pending assays from the M&I Conversion Program, and seven drillholes are pending assays from the Resource Expansion program.
  • Modelling of the M&I Conversion Program drillholes is now underway, with an updated mineral resource estimate on track for Q3, 2025.

Blackrock Silver Corp. (TSXV: BRC) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") announces additional high-grade silver and gold drill intercepts from the M&I Conversion Program (as defined herein) at its 100% owned Tonopah West project ("Tonopah West") located in Nye and Esmeralda Counties, Nevada, United States.

The Company is currently in the process of completing its in-fill drilling program at Tonopah West which commenced in mid-July 2024 and consists of 62 drillholes within the shallow southern portion of the Bermuda-Merten vein group ("DPB South") resource area (the "M&I Conversion Area") with a goal to convert up to 1.0-million tonnes of material from inferred mineral resources to measured and indicated mineral resources (the "M&I Conversion Program"). The M&I Conversion Area represents the initial years of production based on the mine plan laid out in the Company's Preliminary Economic Assessment on Tonopah West (see September 4, 2024 news release).

Andrew Pollard, the Company's President and Chief Executive Officer, stated: "Additional results from our M&I Conversion Program continue to validate our model, supporting mineral continuity as we track and define the geometry of the high-grade shoots within the vein system. Today's results, coupled with results previously announced from this same program, highlight that broader intercepts are associated with higher-than-average grades which should be beneficial in delineating high-grade tonnes. The broad zones of high-grade mineralization encountered in drillhole TXC-138 are a standout for us, as at a composite of 11.46 metres of 514 g/t AgEq (290 g/t Ag & 2.48 g/t Au), this is thickest (composite) zone we've drilled throughout the district outside of the historic Victor mine. As we await the final assays from the M&I Conversion Program, modelling has begun for our upcoming mineral resource update on Tonopah West, currently on track for Q3, 2025."

AgEq = Ag + Au*(Factor); where Factor = (Au Price/Ag Price)*(Au Recovery/Ag Recovery or
Factor=($1900/$23)*(95%/87%)=90.21; True thickness is 90 to 100% of interval thickness based on the modelled
vein geometries; Cut-off grade is 150 gpt AgEq; Reverse Circulation (RC)/Core = RC pre-collar with core tail.

 

As is evident from Table 1, the highest-grade results are associated with thicker intercepts of quartz vein material. This is similar to previous results seen from the M&I Conversion Program where broader intercepts were encountered, such as: TXC24-095 which returned 5.03 metres of 774.5 g/t AgEq (461.5 g/t Ag and 3.47 g/t Au),1 TXC24-119 which returned 4.69 metres of 714 g/t AgEq (379.0 g/t Ag and 3.72 g/t Au),2 and TXC24-122 which cut 5.21 metres of 563 g/t AgEq (3.02 g/t Au and 292 g/t Ag)3 .This combination of high grade and thickness should have a positive impact on the proposed development of the M&I Conversion Area and the scheduled mineral resource update. Modelling of the M&I Conversion Program drillholes has started and an updated mineral resource estimate on Tonopah West is currently scheduled for Q3 2025.

The geometry of the high-grade silver and gold is sizable with high-grade shoots plunging to the northwest within the M&I Conversion Area. These shoots are open to the northwest, east and open down plunge. TXC25-138 shows high-grade shoots have thicker vein intercepts along the axis of the shoot and multiple high-grade intercepts are being returned under the M&I Conversion Program. Allowing for the 3 metres of internal waste, TXC25-138 would have a drill interval of 11.46 metres grading 290.2 g/t Ag and 2.48 g/t Au or 514.3 g/t AgEq. The thickness of this mineralized shoot is approaching those seen in the historic mining at the Victor and Ohio mines where the Victor vein area was 24 metres thick and the Ohio vein area was 15 metres thick4.

Drillholes TXC25-133, -134, -135, and TXC25-136 returned silver and gold assays below the cutoff grade for Table 1. The drillholes returned silver equivalent grades ranging between 100 and 144 g/t AgEq with silver values ranging between 6 to 71 g/t and gold values between 0.51 and 1.34 g/t. There are ten drillholes (TXC25-137, -139, -141, -142, and TXC25-146 to -TXC25-151) with pending assays from the M&I Conversion Program. In addition, seven drillholes are pending assays from the Company's exploration drill program that is targeting expansion potential across a one kilometre trend of vein corridor linking the Denver-Paymaster and Bermuda-Merten vein groups and the Northwest step out resource area at Tonopah West (the "Resource Expansion Program") (see February 24, 2025 news release).

Quality Assurance/ Quality Control

All sampling is conducted under the supervision of the Company's project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The RC and core samples are hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they are loaded on to American Assay Laboratory's (AAL) flat-bed truck and delivered to AAL's facility in Sparks, Nevada. A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company's instructions.

The RC samples are lined out at the lab and logged in to AAL's system. The core samples are cut using core saws and personnel at AAL's facility in Sparks, Nevada according to the Company's instructions delivered with each core hole.

All samples are dried, crushed to 85% passing 10 mesh (2mm) and a 250-gram sub-sample split is collected and pulverized to 200 mesh (74 micron) in a ring and puck pulverizer. Then the pulverized material is digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split (FA-PB30-ICP). Silver is determined using five-acid digestion and ICP analysis (ICP-5AM48). Over limits for gold and silver are determined using a gravimetric finish (GRAVAU30 and GRAVAG30). Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or a certified reference material approximately every 15th to 20th sample.

Blackrock Silver Commences Eastern Expansion Drill Program Targeting 1.2km Trend at Tonopah West

Scout Drilling Discovered the Extension of the High-grade Merten Vein Creating an Opportunity to Expand the Dpb Resource up to 1,200 Metres to the East

SCOUT PROGRAM HIGHLIGHTS:

  • Assay results from the Company's reverse circulation Scout Drill Program (see March 31, 2025 news) returned significant gold & silver values in 7 drillholes that successfully expanded the footprint of mineralization up to 1,200 metres from the east of the existing DPB resource toward the historic Ohio mine;

  • These intercepts cover a new zone of silver and gold interpreted to be the outer ring structure of the Fraction caldera, and are not included in the 2024 resource;

  • A fully funded 15 drillhole program totalling up to 5,000 metres is underway; and

  • Results from this program will be incorporated into an updated Mineral Resource Estimate in Q1, 2026.

Vancouver, British Columbia--(Newsfile Corp. - July 21, 2025) - Blackrock Silver Corp. (TSXV: BRC,OTC:BKRRF) (OTCQX: BKRRF) (FSE: AHZ0) ("Blackrock" or the "Company") announces commencement of a fully-funded expansion drill program ("Expansion Program") to follow up on the successful Scout Drilling campaign that expanded the DPB South zone 1,200 metres in an easterly direction on its 100% owned Tonopah West project located in Nye and Esmeralda Counties, Nevada, United States.

The Expansion Program will utilize one Reverse Circulation (RC) drill overseen by Legacy Drilling and two core drill rigs operated by Alloy Drilling to complete 2,450 metres (8,000 ft) of RC precollars and 2,550 metres (8,400 ft) of core tails across 15 drillholes targeting the Eastern Expansion zone between the DPB resource area and the eastern extent of the project. Drilling is anticipated to be completed in October with assay results expected through year end.

Andrew Pollard, Blackrock's President and CEO, stated, "With drills now turning on this fully financed program, we're stepping out across a 1.2-kilometre corridor with strong potential to significantly expand our mineral inventory at Tonopah West. Scout drilling confirmed the eastern extension of the high-grade Merten vein well beyond the current resource boundary, returning standout grades including 2,063 grams per tonne (g/t) silver equivalent (AgEq) (1,198 g/t silver (Ag) and 9.6 g/t gold (Au)) over 1.52 metres, and 952 g/t AgEq (10 g/t Ag and 10.5 g/t Au) over 4.57 metres. This newly defined zone, situated along the outer ring structure of the Fraction caldera, lies entirely outside our 2024 resource and presents an opportunity to quickly and meaningfully grow the scale of the project. Results from this program are expected to underpin a resource update in Q1 2026. The Company remains on track to deliver a separate resource update in Q3 2025 that will incorporate all results from the recently completed M&I conversion program."

As announced on March 31, 2025, the Company discovered the 1,200 metre eastern extension zone representing the continuation of the outer-ring structure or Fraction caldera margin from DPB South to the historic Ohio mine. The Scout Drilling showed the Merten vein extends eastward and is arched and dips southward. This orientation suggests multiple ring structures associated with the Fraction caldera running across Tonopah West. An inner structure hosting the Victor and DPB North (Denver and Paymaster) resources, and an outer, more southern, ring structure hosting DPB South (Merten and Bermuda) and the NW Stepout resources (See Figure 1). The arching geometry of the Merten vein is similar to that described from the historic Ohio vein which was 15 metres thick when mined in the early 1900s1. Given the geometry and location, the Merten is potentially the extension of the Ohio vein. Table 1 summarizes the Scout Drilling assay results above 150 g/t AgEq.

Quality Assurance/ Quality Control

All sampling is conducted under the supervision of the Company's project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The RC samples are hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they are loaded on to American Assay Laboratory's (AAL) flat-bed truck and delivered to AAL's facility in Sparks, Nevada. A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company's instructions.

The RC samples are lined out at the lab and logged into AAL's system. The samples are dried, crushed to 85% passing 10 mesh (2mm) and a 250-gram sub-sample split is collected and pulverized to 200 mesh (74 micron) in a ring and puck pulverizer. Then the pulverized material is digested and analyzed for gold using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split (FA-PB30-ICP). Silver is determined using five-acid digestion and ICP analysis (ICP-5AM48). Over limits for gold and silver are determined using a gravimetric finish (GRAVAU30 and GRAVAG30). Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or a certified reference material approximately every 15th to 20th sample.

Locksley Resources Limited Assessment and Evaluation of DeepSolv Program Expansion

Perth, Australia (ABN Newswire) - Locksley Resources Ltd (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) is pleased to advise that a senior Locksley team has completed a visit to Rice University in Houston, Texas, to formally evaluate the Company's research collaboration with Rice.

Highlights

- Given increased industry interest in DeepSolv(TM), the Company has requested the expansion & acceleration of the Rice technology program

- The expansion would include the following components:

o Testing of multiple antimony feedstocks at different processing stages, direct ore, post DMS and high-grade concentrates

o Testing of antimony feedstock from multiple sources including the Mojave Project, EV Resources and additional other 3rd party samples

- Meetings held with Professor Pulickel Ajayan, Rice Executive Vice President for Research, and Technology Transfer Office

- Dedicated project workshop with the Ajayan research team to discuss technical programs

- Locksley in discussions with an additional mining group regarding the opportunity of evaluation the DeepSolv(TM) technology

- Locksley is focused upon providing Antimony processing independence to the USA and the opportunity presented by the $1.5bn+ domestic market

During the visit, the Locksley team met with Professor Pulickel Ajayan and members of his laboratory, senior Rice administrators including the Executive Vice President for Research and the Office of Technology Transfer and representatives from Rice Public Affairs. These discussions were followed by a dedicated project workshop with the Ajayan group, providing the foundation for the joint technical program under the collaboration.

The work program, formally launched through this visit, will focus on two parallel thrusts:

1. The development of DeepSolv(TM) product, for the extraction and refining of antimony feedstocks

2. The evaluation of antimony-based materials for advanced energy storage applications

As previously announced, Locksley has secured an agreement with EV Resources for the supply of external antimony ore, which will be incorporated alongside feedstock from the Mojave Project to support the development of DeepSolv(TM). In addition, DeepSolv(TM) continues to gain industry momentum, with discussions now underway with an additional potential user for the treatment of antimony ore. Given the growing industry interest in DeepSolv(TM) the Company is actively evaluating options to expand and accelerate the Rice technology program.

Locksley views the Rice partnership as a cornerstone of its U.S. strategy, providing access to world class expertise and positioning the Company to advance both upstream and downstream opportunities in antimony and rare earths.

Locksley's Chairman Patrick Burke, commented:

"This visit marks an important milestone in Locksley's mine-to-market strategy to onshore the supply of antimony and rare earths into the United States. By formally commencing our collaboration with Rice University and incorporating additional ore supply secured through our agreement with EV Resources, we have laid the foundation for a practical and accelerated testwork program. These initiatives position Locksley at the centre of developing a secure domestic supply chain, aligned with U.S. government priorities. We look forward to working closely with Professor Ajayan and his team as we move rapidly toward delivering tangible results."

About Locksley Resources Limited:

Locksley Resources Limited (ASX:LKY,OTC:LKYRF) (FRA:X5L) (OTCMKTS:LKYRF) is an ASX listed explorer focused on critical minerals in the United States of America. The Company is actively advancing exploration across two key assets: the Mojave Project in California, targeting rare earth elements (REEs) and antimony. Locksley Resources aims to generate shareholder value through strategic exploration, discovery and development in this highly prospective mineral region.

Mojave Project

Located in the Mojave Desert, California, the Mojave Project comprises over 250 claims across two contiguous prospect areas, namely, the North Block/Northeast Block and the El Campo Prospect. The North Block directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials' claims, highlighting the strong geological continuity and exploration potential of the project area.

In addition to rare earths, the Mojave Project hosts the historic "Desert Antimony Mine", which last operated in 1937. Despite the United States currently having no domestic antimony production, demand for the metal remains high due to its essential role in defense systems, semiconductors, and metal alloys. With significant surface sample results, the Desert Mine prospect represents one of the highest-grade known antimony occurrences in the U.S.

Locksley's North American position is further strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE & antimony production. With its maiden drilling program planned, the Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security.

Tottenham Project

Locksley's Australian portfolio comprises the advanced Tottenham Copper-Gold Project in New South Wales, focused on VMS-style mineralisation
