Mammoth Identifies Draw Point Locations for Future Small-Scale Gold-Silver Mineral Extraction and Pilot Leach Testing at its Tenoriba Gold-Silver Property, Mexico

(TheNewswire)

Toronto, Canada – TheNewswire - (February 26,2026) - Mammoth Resources Corp. (TSX-V: MTH), (the“Company”, or “Mammoth”) is pleased to announce the selection ofpotential draw point locations for its small-scale, gold-silvermineral extraction and pilot leach test at the large Carneritos areawithin its 100% owned Tenoriba project, Chihuahua State, Mexico.

Company geologists have sifted through a combination of thousands ofsurface chip, channel and nearest drill-hole gold-silver assayresults, combined with studying geological features and access pointsto identify areas with higher-than-average grades that would serve aspotential draw points for small-scale, gold-silver mineral extractionand pilot leach test within the large 1.5 by 0.5 kilometre Carneritosarea. Refer to Table 1 - Average Grades within Draw Point Locations,accompanied by Figure 1 - Location Map- Mineralized Areas within the Tenoriba Project and Figure 2 -Location Map - Carneritos Area Draw Points, which illustrate theaverage grades associated with each draw point and the locations ofthese draw points within the Tenoriba project and Carneritos area,respectively.

Thomas Atkins, President and CEO ofMammoth Resources, commented on these draw points, stating:"We've combed throughthousands of surface and drill sample results, studied the geology,soil sample results and geophysics and have identified severalattractively mineralized areas from which we believe potential existsto extract initial volumes of gold-silver mineralized rock fromsurface to shallow depths and from which initial pilot leach scaletesting could be performed. Next steps will be to go to site and fieldcheck these locations to assist in defining their surface footprintand gain an approximation of their size and the potential tonnagethese areas might host. 

We're excited by the gradesevident at surface, with the averages from numerous samples at orabove one gram per tonne gold equivalent and up to almost four gramsper tonne and the potential to efficiently recover this gold andsilver from these areas via pilot leaching."

Recommendations forfuture work include site and field check of these draw point locationsto assist in defining their surface footprint and gain anapproximation of their size and the potential tonnage these areasmight host. Additional metallurgical testing will be performed oncoarser-grained, near-surface oxidized and oxidized-transition zonematerial from these draw points and other mineralized areas, possiblyin bottle roll tests, or column tests. Thismaterial should be crushed and screened for a 3/8-inch diameter sizefraction, followed by column testing to determine leach kinetics.These tests would further validate and enhance the confidence of themetallurgical recoveries of gold and silver by cyanide heap leachmethods, plus the consumption of reagents to achieve themost favourable gold andsilver recoveries and the potential economics ofthis process.

The Company looks forward to reporting on additionaldevelopment activities at Tenoriba, including results from the sitevisit and additional metallurgical testing, plus resource definitiondrilling.

Quality Assurance and Quality Control(QA/QC):

Samples referenced in this press release wereprepared and analyzed by ALS laboratories (ALS) in their facilities inMexico and Canada, respectively. Samples generally consisted of aminimum of 2 kilograms of material. Drill core is mostly HQ diametercore with minor lengths of NQ diameter core. Core is sawn in half witha rock saw, with one half used for sample analysis purposes. Wherechip and channel samples are taken, these are most often 1.5 metres inlength; only in poor recovery sections do they exceed this length,with rare exceptions exceeding a maximum of 4.5 metres in length.Samples are collected with a sample ticket and deposited into plasticsample bags sealed with nylon zip lock ties, then loaded into grainsacs similarly sealed with a nylon zip lock tie prior to transport byMammoth personnel to ALS’s facility in Chihuahua, Mexico, for samplepreparation. Gold and silver analyses are performed in ALS’sfacility in Canada via a 30-gram fire assay with an atomic absorptionfinish. Silver, copper, lead and zinc are analyzed as part of amulti-element ICP package using a 4-acid digestion. Blank andduplicate samples are inserted randomly at approximately every 15samples. Drill core assay results, plus Quality Assurance/QualityControl (QA/QC) measures, were previously reported in various pressreleases (refer to Mammoth website press releases spanning the periodNovember 18, 2021, to December 15, 2022).

Qualified Person / Competent Person(QP/CP):
