Castile Resources Limited announced of the results from the June 2022 DHEM survey of hole NR142D003 at Castile's 100% owned Explorer 142 Prospect located 32 km to the west the Company's flagship Rover I Project. The purpose of the survey was to test an interpreted off-end of hole anomaly identified from modelling results of 2021 resurvey of historic hole NR142D003. Drill hole NR142D003 was successfully extended from 815m to 982m and re-cased at the end of the 2021 field season.

Gap Geophysics used a single transmitter loop for the survey with the results then remodeled by independent geophysics specialist Newexco and the modelling results then subject to review by the Castile Resources technical team. The anomalism in the hole is complex due to the super position of signal from multiple sources. The new survey has improved the quality of the initial field data, identifying two anomalies: an early time on-hole anomaly with interpreted conductive source associated with known ironstone; and a mid time off-hole anomaly with interpreted conductive source that is not associated with known ironstone bodies.

Castile will work up a strategy for this target at Explorer 142 in the ensuing period once results of all 2022 field work across Castile's tenements is received and targets prioritized. The Company notes that results from the DHEM survey at Explorer 108 are pending in addition to ground gravity surveys continuing at various other targets within Castile's Rover Project. The results of these surveys will be presented to the market as they become available.
