Atlas Salt announces that drill hole CC-9b, collared 250 meters east of CC-4 into an untested part of Great Atlantic, has cut a 336-meter gross interval of salt highlighted by thick sections of massive salt comprising 305.5 meters grading 95.56% sodium chloride (NaCl - salt). The first major section (168 meters) of massive salt started at a depth of only 240 meters, and included 6.39 meters of 99.1% salt, further solidifying Great Atlantic as the shallowest deposit in the heart of the robust North American road salt market; High-grade massive salt is continuous throughout almost the entire drill hole from 240 meters (see attached table), interspersed with only three minor intervals of salty mudstone; Very high purity salt (98.15%) occurs near the bottom of the drill hole over 14.2 meters within a broader 81.5-meter section grading 95.87%; Analytical results for CC-9b were not available prior to the effective date of the recent SLR Technical Report (Preliminary Economic Assessment - PEA) and are therefore not included in the current resource estimate. Inclusion of these results will upgrade the Great Atlantic salt resource in the upcoming Feasibility Study.

Given that the deposit is flat lying to gently dipping, drill lengths reported above closely approximate true width. Diamond drill hole CC-9b was completed between November 24, 2022 and December 20, 2022 at location 388362E, 5363314N, UTM NAD83 Z21. The hole was drilled vertically (CC-9a was abandoned for technical reasons at shallow depth and restarted as CC-9b).

CC-9b intersected a 336-meter gross interval of salt that included four sections of massive high- grade salt and three minor sections of salty mudstone (408 m to 426 m, 472 m to 483 m, and 493 to 494.5 m). Drill core from CC-9b, through the salt interval, is NQ in diameter (47.6mm). Samples were taken in lengths of whole core at a minimum of 0.10 m in length per sample.

A total of 189 samples were taken over a gross interval of 336 m with a sample ratio of 1.77, averaging 1 sample per 1.7 meter of core. All samples taken from CC-09b were sent to Actlabs in Ancaster, Ontario, and analyzed for NaCl (salt) by ASTM D632-12 analytical package. Drill core was collected from the drilling site by Atlas geological staff.

Drill core was then transported to a secure core storage facility in Stephenville, Newfoundland, for logging and sampling. Core sample tags were placed in the core box and sample bags, with a third tag placed in a record book. All sample record books are stored at the Atlas offices.

Samples were placed in individual sealed and labelled plastic bags and sample shipments are accompanied by sample inventory sheets. Atlas geological staff delivered sample batches to the courier and received tracking details, after which samples are transported by courier to the Actlabs laboratory in Ontario.
