Tipperary area, ELs 6647-6650, 6652, 7380-7382, annual report for the period ending 21-06-1993

Abstract

During the reporting period 3 anomalous chromites were followed up with close intervel heavy mineral sampling. Follow up of the chromites was disappointing. Two magnetic anomalies remained of interest after follow up. During this reporting period, these were tested with 4 drill holes. All drill samples analysed were negative. An additional follow up of 3 garnets recovered in 1991 was also completed. This involved the collection of 56 infill samples and 399 loam grid samples. Only one kimberlitic garnet has been found, and this may represent the source point for a number of the garnets recovered thus far. An aeromagnetic survey was flown in poorly drained areas, hoping to detect kimberlites not located by sampling. Five anomalies were chosen for further work. Landsat TM imagery was re-examined and 5 anomalies were selected for follow up sampling.
