Vancouver, British Columbia--(Newsfile Corp. - August 25, 2026) - Maverick Gold and Silver Corp. (CSE: MAV) (FSE: VR61) (OTC Pink: VRCFF) ("Maverick" or the "Company") announces that the results from its first comprehensive sampling program at the Jericho Property, Lincoln County, Nevada, have confirmed the significant potential for the property.

Summary:

The first work program at the Jericho property accomplished the following:

• Created a comprehensive property-wide baseline rock geochemistry database.

• Results range from trace to 7.21 grams per tonne (g/t) (or 0.21 oz/T) gold and trace to 644.0 g/t (or 18.87 oz/T) silver.

• Confirmed widespread distribution of Ag and Au on both the East and West trends.

• Established continuity of mineralization along two kilometres of strike length with higher grade material in two zones with each one being over two hundred metres.

• Confirmed the importance of silver as a dominant element in the mineral system.

• Identified the potential for a bulk tonnage target with limited sampling of stockwork footwall zone.

Highlights from the sampling program are listed below in Table 1 (see following sections for added details):

The Jericho property is host to epithermal silver and gold mineralization that is made up of quartz veins, breccias, and stockwork zones. The known mineralization has been identified within two sub-parallel northeast striking structural corridors: the West Trend, which is made up of the Helen, Tempa, Fluorite Flat, Upper Flats and NE Extension Zones, has been traced for in excess of 4 kilometres and the East Trend, which is made up of the President's, Miramonte and Northeast Zones, has been traced for 2 kilometres.

The West Trend is a structurally controlled linear mineralized system with the Helen and Tempa Zones representing concentrations of higher-grade mineralization that are characterized by large low-sulfidation epithermal quartz veins and stockworks.

The Helen Zone is the largest past producer; the Tempa Zone is notable for very high silver grades. The President's Zone is known for having higher gold grades. All zones remain underexplored and present strong targets for further drilling and exploration.

Phase 1 Jericho Field Program:

A total of 171 chip channel and grab samples were taken throughout the property. This news release reports the results from 153 of those samples, which were taken in the central and southern portion of the property and concentrated on the Helen, Tempa, and President's Zones. Results range from trace to 7.21 grams per tonne (g/t) (or 0.21 oz/T) gold and trace to 644.0 g/t (or 18.87 oz/T) silver.

The samples included 133 chip channel and 20 grab samples taken from the mineralized dumps that were beside the historic workings. "Wherever possible the dump material beside the workings was sampled. Grab samples from the mine dumps are important because, although it is unknown as to what depth the material comes from, the mineralization within the dumps give indications of the style and tenor of mineralization from within the working", stated Ian Foreman, P.Geo., VP, Exploration of Maverick Gold and Silver. "At this early stage of exploration, it is the only way to get a view into the third dimension other than drilling."

The field program also confirmed the location of thirteen (13) historic workings within the property. These workings include shafts, adits and excavations. The shafts vary in depth from several to in excess of 15 metres but a majority of them are collapsed so the actual depth remains unknown. The adit at the Miramonte Zone was measured as being in excess of 100 metres but was not fully investigated due to fear of it containing stale air.

The Tempa Zone: (refer to Figure 1)

The Tempa Zone is made up of a 2- to 10-metre-wide quartz/adularia vein and breccia that has been traced on surface for 800 metres. An associated stockwork zone, located in the footwall of the vein and breccia, is locally in excess of 10 metres but measurements are inconsistent as a majority of the area immediately to the east of the Tempa Zone is under shallow overburden.

The core of the zone, termed Tempa Central, is predominated by waxy green silica that occurs as laminar bands, the matrix of brecciated vein material, and as pseudomorphs within open cavities. A majority of the sampling was taken though this zone, which measures approximately 200 metres. The rest of the Tempa Zone was tested with between 50 and 100 metres between sample lines.

Highlights from the sampling within the Tempa Zone are listed below in Table 2:

Samples 371 to 375 represent the only series of samples that tested the footwall stockwork zone at Tempa. The immediate 1.2m below the footwall of the vein was covered with shallow overburden - a sample through this area retuned 0.325 g/t Au and 42.74 g/t Ag over 0.95 m.

The Helen Zone: (Refer to Figure 2)

The surface expression of the mineralization within the Helen Zone tends to occur multiple-metre-wide quartz/calcite veins and stockwork. Hosted in andesite, the NE-striking quartz veins and stockworks are up to 20 metres wide and have been traced on surface for over nine hundred (900) metres.

Mineralization is associated with coarse crystalline quartz, crustiform and colloform banding, and comb textures. There is a very high calcite content to the mineralization.

The Helen vein dips 40 degrees east and has two subvertical shafts as well as one adit. The Helen Zone is reported to have been the largest source of historic production within the property; however, the Company is not in possession of any production records.

Highlights from the sampling within the Helen Zone are listed below in Table 3:

President's Zone: (Refer to Figure 1)

The President's Zone has been traced for approximately 200 metres, and mineralization occurs as a 1.5- to 2-metre-wide quartz/calcite vein with an associated stockwork zone in the footwall. It is hosted in andesite, with quartz veins and stockworks showing strong silicification and argillic alteration.

The President's Zone is the southernmost zone within the East Trend, which strikes at N50E, and has consistently contained the highest gold values within the property, both in the Company's sampling and historic sampling.

Interpretation:

The Jericho property is host to a particularly silver rich mineralizing system that appears to have a much lower trace metal signature than mineralization associated with typical low sulphidation deposits. The arsenic, antimony, bismuth and tellurium values from this recent sampling, for example, are below the levels that would be considered anomalous in typical low sulphidation deposits. Both mercury and molybdenum values are the exception and would be considered strongly anomalous in a typical low sulphidation system.

Each zone contains multiple phases of veining and mineralization, with evidence of repeated fault movement indicating that there have been several phases of hydrothermal activity within the system. The Company interprets that the presence of opaline/chalcedonic quartz and adularia at surface within the Tempa Zone suggests that the boiling zone is below current exposures, which would indicate that there is potential for continued mineralization at depth.

Where exposed in a roadcut, the footwall stockwork zone of the Tempa Zone indicates that mineralization continues, locally, up to 7.6 metres from the principal mineralized structure. Along the length of the central Tempa Zone there is float that contains similar stockwork. The presence of these boulders suggest that the footwall zone is continuous along the length of the target.

The Helen and Tempa Zones have a very high silver-to-gold ratio; in many cases it is greater than 1,000:1. When compared to other silver-rich mineralizing systems in Nevada, the Company has yet to find another deposit that has a comparable silver to gold ratio. More studies will be required to understand the reasons for such a high silver to gold ratio and, more importantly, the significance of it with regards to exploration within the property and identifying the most favourable targets for drilling.

Next Steps:

The Jericho Property warrants significant additional work and drilling is warranted. Prior to a drill program, however, the Company plans to continue de-risking the project with additional sampling and mapping programs.

Option Terms:

The Company has the right to acquire a 100% interest in the Jericho Property by making cash payments totaling US$250,000 over a four-year period with $15,000 having been paid. Upon exercise of the Option, there will be a 3.0% net smelter royalty on all mineral production from the Property.

Analytical Methods, Laboratory and QA/QC Information:

All samples were delivered by Company personnel to ALS in Reno, Nevada, an ISO/IEC 17025:2017 accredited laboratory that is independent of the Company.

Gold analyses were completed using fire assay with atomic absorption finish (method Au-AA23) on a 30-gram aliquot. Samples returning over-limit gold values were reanalyzed using fire assay with gravimetric finish. Silver and multi-element analyses were completed using four-acid digestion with ICP-AES finish (method ME-ICP61).

ALS inserted certified standards, blanks, and duplicates in accordance with its accredited internal quality control procedures. The laboratory has no relationship with the Company.

As part of the Company's quality assurance and quality control program, commercially prepared and certified reference standards as well as proprietary blank samples were inserted at regular intervals into the sample series, comprising approximately 5% of the samples submitted. The blanks were used to monitor potential contamination during sample preparation and analysis, while the certified reference standards were used to assess analytical accuracy and laboratory performance. QA/QC results were reviewed as assay certificates were received, and all blanks and standards reported within the Company's established acceptance limits; accordingly, no material QA/QC issues were identified.
