Patriot Drills 1.25% Li2O over 96.9 m in First Drill Hole of Summer Program, and Extends Strike Length of Pegmatite to 1.9 km, Corvette, Quebec - Seite 3

Drill hole CV22-036 was collared 100 m along strike to the west-southwest of CV22-034 with the objective of extending the main spodumene pegmatite along strike from the CV5 outcrop to the CV6 outcrop (Figures 1). The hole was successful and encountered multiple and distinct pegmatite intersections ranging from <1.5 m to 27.0 m, returning 1.38% Li₂O and 99 ppm Ta₂O₅ over 27.0 m, and 2.00% Li₂O and 167 ppm Ta₂O₅ over 7.3 m.

The summer phase of the 2022 drill campaign began in early June with two diamond drill rigs operating along the CV5-1 pegmatite corridor. A barge and third drill rig have now arrived at site with both to be positioned on the shallow lake, overlying portions of the mineralized pegmatite, for lake-based definition drilling throughout the summer and into the fall period.

Quality Assurance / Quality Control (QAQC)

A Quality Assurance / Quality Control protocol following industry best practices was incorporated into the program and included systematic insertion of quartz blanks and certified reference materials into sample batches, as well as collection of quarter-core duplicates, at a rate of approximately 5%. Additionally, analysis of pulp-split and course-split sample duplicates were completed to assess analytical precision at different stages of the laboratory preparation process, and external (secondary) laboratory pulp-split duplicates were prepared at the primary lab for subsequent check analysis and validation.

All core samples collected were shipped to SGS Canada’s laboratory in Lakefield, ON, for standard sample preparation (code PRP89) which includes drying at 105°C, crush to 75% passing 2 mm, riffle split 250 g, and pulverize 85% passing 75 microns. Due to capacity issues, SGS forwarded several sample batches to alternate preparation labs in Sudbury, ON, and Burnaby, BC. The pulps were shipped by air to SGS Canada’s laboratory in Burnaby, BC, where the samples were homogenized (if preparation was not at Burnaby) and subsequently analyzed for multi-element (including Li and Ta) using sodium peroxide fusion with ICP-AES/MS finish (code GE_ICM91A50).
