Classic Minerals has delivered more high-grade gold intercepts from infill RC drilling at the company’s flagship Kat Gap gold project, 170km south of Southern Cross in WA. Significant results include a 1m hit going 40.1 grams per tonne gold from 33m within a 2m intercept at 21.07 g/t also from 33m.
Another hole returned 2m grading 17.2 g/t gold from 53m including 1m running 19.9 g/t from 53m.
The results come from another 14 holes of Classic’s 109-hole infill program designed to provide more accurate data for the company’s resource model as it looks to start producing.
Assays displaying a high calibre of gold hits from the first 10 holes of the program were reported at the start of the month. Highlights included a 1m hit going 19.4 g/t gold from 44m within a 3m intercept at 7.04 g/t from 43m and another hole that delivered 1m running 17 g/t from 34m within a 3m strike grading 13.23 g/t from 32m.
The latest 14 reported holes were located immediately south and along strike from the first 10 holes.
Infill work focused on an area 100m to 300m north along strike of the cross-cutting Proterozoic dyke featured within the project.
Classic has now drilled a total of 24 holes for 1445m and plans to drill another 85 RC holes for approximately 5665m.
The company launched an infill program after the findings from a recent bulk mining sample operation exposed evidence of slight variations in the shape of the ore body over intervals of about 10 to 15m.
Further infill drilling will provide Classic with a higher level of confidence in the overall status of the current resource block model and permit an upgrade of Kat Gap’s inferred resource to indicated status before a final pit design.
The Kat Gap deposit of 93,000 ounces grading 2.96 g/t gold is the highest-grade contributor to the company’s total gold inventory of just over 400,000 ounces.
The company says the infill program will also dramatically reduce the number of grade control RC holes it will have to drill once production starts.
Most of the drilling will consist of relatively shallow holes down to depths of up to 70m, however in some cases holes will be drilled down to as far as 140m to extend the known gold mineralisation at depth.
Classic says the program should take four to six weeks to complete depending on the weather. Drilling operations were suspended last week because of severe weather conditions.
Drilling is expected to kick off again in a few weeks.
