Highlights:

• The East Curlew target is the eastern extension of the Curlew fault, which is an important fault at the historic Page and Blackhawk mines, which hosts the Curlew Vein, and the prolific Tony Vein
• First assessment with modern exploration techniques of the Curlew fault along its eastern corridor.
• A very large and significant near surface coincident Induced Polarization and Resistivity anomaly measuring 450 metres of strike length and 300 metres of down dip extension from near surface reflects a high potential to discover a complimentary mineralized system to the Blackhawk Mine along the Curlew Fault.
• Strong and highly anomalous surface geochemistry sample results in silver, zinc, lead, and copper are located near and on top of the geophysical anomalies further validating the importance of the East Curlew target.
• The East Curlew target is located approximately 230 metres east of the historic Blackhawk mine, in the footwall of the projected Curlew Fault.
• The East Curlew target is also located between the Crown Point mine to the north, 500 metres, and the Ranger-Wyoming Complex to the south, 200 metres - these high-priority drill target areas are all located within a relatively small 700 metre X 700 metre footprint.
• One of seven high priority large target areas defined from the 2022 exploration campaign constrained within a relatively small 3km x 2km area.

"We are pleased to see that the mapped Curlew Structure continues to show significant promise along its eastern extension from the past producing Blackhawk mine. Coincident ground IP, geochemical results, and mapped alteration of host rocks further validate East Curlew's high rank among our long list of near surface targets. East Curlew's proximity to historic mine infrastructure means successful drilling could lead to rapid development for further testing of this near surface mineralization. We look forward to testing the East Curlew target during our 2023 drilling campaign," comments Brandon Rook, CEO of Silver Valley Metals.

The East Curlew target is located approximately 230 metres east of the historic Blackhawk mine, in the footwall of the projected Curlew Fault. The Blackhawk mine was mined to the 1200-foot level and remains in mineralization with an approximate 375 metre strike length at the 1200-foot level, this being supported from underground maps secured from the past operator. The East Curlew target at near surface is a complimentary target to the Blackhawk mine as it may have the potential to open future mining opportunities at the Blackhawk mine with a successful near surface and at depth drilling campaign at East Curlew.

The East Curlew target is also situated between the Crown Point Mine 500 metres to the north and the Ranger-Wyoming Complex, 200 metres to the south, two areas with past production but only near surface no greater than 200 feet below surface; both of these areas are considered open at depth and laterally along strike and are a high priority to drill this year; all of these targets may potentially help assist the re-opening of the Blackhawk mine, and further to that, the re-opening of the top-ten historical producer in the Silver Valley, the Page Mine that is located 750 metres to the west of the Blackhawk mine.

The East Curlew target is one of seven high priority target areas that the Company has defined from its successful 2022 exploration campaign. Importantly, all high priority areas are constrained to a compact area approximately 3 kilometres by 2 kilometres and each target shows significant strike and depth potential.

Background polarity observed in the host rock is typically between 0 and 4 msec, as compared to the +20 msec background observed in the Prichard formation to the north of the Osburn Fault. The East Curlew polarity anomaly is strongest near surface (0-200 metres deep), with highest values between 8 and 12 msec. The strike length of this anomaly is approximately 450 metres. The depth extension below 300 meters is promising, but less contiguous as the upper anomaly. High overlapping resistivity data at the East Curlew target is interpreted to be silicic alteration associated with a potential mineralized system.

After identifying the ground IP anomalies, a surface geochemical program was initiated to further validate the perceived IP targets. Soil geochemistry sampling over the IP anomaly shows silver values up to 0.6 opt Ag (21 g/t Ag) compared to a background of <0.1. Lead, Zinc and Copper anomalies are as high as 1,790 ppm, 405 ppm, and 419 ppm respectively. Background levels of lead, zinc and copper in the project area are typically 10 ppm, 40 ppm, 6 ppm respectively based on all 2022 Silver Valley Metals geochemical data. Trace element vector analysis is ongoing, and we expect that will further validate the East Curlew target.

A north-south soil grid oriented over the Induced Polaization anomaly was used to guide sample locations. Samples of the B and C soil horizons were collected on a 30 metre spacing. At each location, a pit was dug until refusal (could not dig deeper). The C and B soil horizons were sampled separately, described, photographed, staked and location data collected via GPS. Results were loaded into Leapfrog Geo and displayed via a proportional grade plot to highlight high values.

Lab Analysis – QA-QC:

Atomic absorption analysis for Silver:

American Analytical Services, Inc ("AAS") is an ISO/IEC 17025 accredited laboratory, located in Osburn, Idaho. All analysis includes quality control measures to ensure an acceptance standard established within AAS methods. All samples sent to AAS were checked for accuracy between the chain of custody and the samples with the client present. Samples are dried before starting the prep process. The prep process includes crushing the sample in its entirety to 80% passing a 10 mesh, split in a riffle box to make a 250g sub-sample and pulverized to 85% passing a 140 mesh. Analysis for AA-Ag is done by 2 or 4 acid digestion. Detection limit for AA-Ag is 0.100 Oz/ton - 15.0 Oz/ton. Any results over the detection limit are sent to fire assay to do Ag gravimetric finish.

ICP-OES analysis for 35 element analysis:

All samples are subjected to a 4-acid digestion. Digestion QC consists of a reagent blank, control standard and for every 20 samples there is a duplicate of a sample pulp to check RPD. To begin ICP-OES analysis, the instrument is standardized with the five working standard solutions (multi-point linear fitting). Samples are then measured with the reagent blank, control standard and a CCV (continuous calibration verification). Once samples are analyzed, all QC is checked, and results are sent to LIMS system to be made into the client's report.

Silver Valley Metals Corp. owns a 100% interest in a lithium and potassium bearing salar complex comprising 4,056 hectares on three mineral concessions (the "Mexican Projects") located on the Central Mexican Plateau in the states of Zacatecas, and San Luis Potosi, Mexico. The NI 43-101 inferred mineral resource contains 12.3Mt of Sulfate of Potash (SOP) and 243,000 tonnes of lithium carbonate equivalent (LCE) and remains open in all directions for expansion.

The Ranger-Page Project ("The Project") is in the Silver Valley, northern Idaho, USA, 60 kilometres east of Coeur d'Alene and 1 kilometre from the I-90 freeway. In 2020 Idaho was ranked the first in the world in policy perception and 9th best mining jurisdiction (Fraser Institute Annual Mining Survey). The Project borders the famous Bunker Hill Mine to the east and for the first time consolidates the western extent of the prolific Silver Valley mining corridor by one operator in the past 100+ years.

The Project comprises 6 historical mines on patented claims, without royalties. The largest of these, the Page Mine, was a top ten producer in the Silver Valley yielding over 1.1 billion pounds of zinc and lead and 14.6 million ounces of silver. The Page Mine has high grade silver-zinc-lead historic reserves and remains open at depth and along strike beyond what has been identified to date.

Historical mining on the properties shared underground infrastructure which connected the larger Page mine with five shallow historic mines within the larger Project area. The Company has underground mining data and surface geological data that supports high grade silver-zinc-lead mineralization present within the shallow, undeveloped mines. These mines remain open at depth, and laterally along strike.

Exploration potential beyond the historic mines is considered significant as modern systematic exploration is being applied to the project for the first time.

Silver Valley Metals Corp. is a Canadian exploration company comprised of a group of experienced exploration, mining, and financing specialists focused on the pursuit of mineral discovery and development. We are focused on the advancement of strategic and precious mineral properties including Lithium-Potash in Mexico and Silver-Zinc-Lead in northern Idaho, USA.
