 Vancouver, British Columbia--(Newsfile Corp. - September 9, 2025) - Chesapeake Gold Corp. (TSXV: CKG) (OTCQX: CHPGF) ("Chesapeake" or the "Company") is pleased to provide a corporate update on the advancement of its proprietary sulphide leach technology ("Technology") and its regional exploration activities at Lucy.
 
 Jean-Paul  Tsotsos, Interim Chief Executive Officer, commented, "The third phase  of Metates' metallurgical work is progressing well, as we work towards a  prefeasibility study ("PFS") in 2026.  Observations from the  columns indicate that the oxidation process is meeting expectations.  In  addition, we are encouraged by the industry's interest in our  Technology and the commencement of third-party test work on three  prospective opportunities.  This testwork represents the first steps in  our strategy to create economic value through the commercial application  of our Technology.  On the exploration front, detailed and systematic  exploration on Lucy suggests that the project footprint may have the  potential to extend over 3 kilometres, as new geological, geophysical  and structural indicators of mineralization are uncovered."

 The  third phase of metallurgical testwork on Metates with the Technology is  advancing as planned. Two large-diameter PFS columns with Metates  material are active, and the test work is on schedule, with early  encouraging results (Figure 1).  Another 26 variability columns with  Metates material are also ongoing, which will be used for the  optimization of the PFS technical study that M3 Engineering &  Technology Corporation has begun work on (Figure 2).  With  modifications, the High Pressure Grinding Roll ("HPGR") test columns within the variability program are showing more promising silver kinetics over the columns completed in 2024.
 
 In  addition to the Metates testwork, Chesapeake identified numerous  projects and mines that may benefit from the application of the  technology.  Industry interest has led to samples from three projects  being sent to the lab for testing, which are also progressing in  parallel with the Metates test program.  This test work is designed to  demonstrate the technology's applicability across a wide range of  deposits with the intention of commercializing the process as an  eventual significant source of value generation for Chesapeake.
 
 Moreover,  the Company has filed its own separate patent applications from this  innovative test work.  Further technology updates from the metallurgical  programs will be provided in 2026.
 
 Lucy Exploration Update

 Over  the past year, Lucy has made several advancements.  An initial  structural geology program identified a potential correlation between  local folding and the Lucy gold skarn mineralization, providing a new  insight into the local mechanism for gold emplacement and the  concentration processes.  This exploration work further identified new  localities on the property that displayed similar structural features,  which previously had limited exploration for gold skarn mineralization.
 
 A new mineralized corridor has been identified in the Central  Zone located approximately 600 metres west of the Discovery Zone.  New  trenching and rock channel sampling have returned 29 metres of 0.94g/t  gold, including 15 metres of 1.33g/t gold and 34 metres of 0.64g/t gold,  including 10 metres of 0.98 g/t gold (Figure 3), which outlines a  potential new 200 metre long corridor that is open in all directions.   Mineralization within this corridor shares several similar  characteristics with the main discovery corridor.
 
 Earlier this year, the Comisión Federal de Electricidad ("CFE"),  Mexico's state-owned electric utility, started construction of a new  powerline in the western part of the Lucy property, transmitting power  along the Pacific coast city network.  The new infrastructure provided  additional accessibility to the Western Zone of Lucy, which was  identified as having geological potential. This zone had seen limited  ground exploration activities aside from geophysical surveys.   Preliminary mapping has identified the presence of new skarns, and rock  channel sampling has returned several occurrences of anomalous copper  grades, including 3 metres of subcrop with 2.0% copper, a 2 metre  interval of 0.59% copper and another locale with 2 metres of 0.45%  copper (Figure 3).
 
 Currently, the team is trenching and  collecting rock channel samples and conducting an extensive soil  geochemistry program, with sampling grids covering the Discovery,  Central, and Western Zones, to expand the scope and scale of the Lucy  system. Over the past year, Chesapeake has revised its drilling permit,  and a more extensive exploration and drilling campaign is planned at the  completion of this phase of work.
 
 The complete assay data table and enlarged revised Lucy exploration map (Figure 3) are available  here.

 Sample Preparation, Analysis and QA/QC Program
 
 All  the assays reported by Chesapeake in this news release are from rock  channel samples. The rock samples were sent to the ALS Global facility  in Zacatecas City, Mexico, for preparation of assay pulps, which were  subsequently sent to ALS labs in Vancouver, Canada, for analysis.
 
 All  rock samples were prepared using a method whereby the entire sample was  crushed to 90% passing -2mm, a split subsample of 1000 g was pulverized  to better than 85% passing 75 microns and then a 250 g pulp was taken.
 
 Samples  were analyzed for gold using 30 or 50 g fire assay fusion with an ICP  finish (Method Au-ICP22). Silver and other elements were analyzed by 4  acid digestion with an ICP finish (Method ME-ICP61).  Gold (>5 ppm)  and silver (>100 ppm) over limits were analyzed by fire assay and  gravimetric finish.
 
 Certified standards and blanks from CDN  Resource Laboratories were inserted into the sample stream as part of  the sampling protocol for the QA/QC program.
