| ABSTRACT: | De Grey Mining Limited (ASX: DEG, “De Grey”, “Company”) is pleased to announce an update on drilling results from the Mallina deposit that forms part of the 1.4Moz Pilbara Gold Project, located near Port Hedland in the Pilbara region of Western Australia. (ASX release “2018 Total Gold Mineral Resource increases to 1.4Moz”, 3 October 2018) At Mallina, a drill program comprising four diamond tails (total 464m) and 15 RC holes (total 1673m), has been completed, with further encouraging results showing along strike extensions outside of the existing resource model (Figure 2). An additional two diamond holes drilled last year for metallurgical purposes have been partially assayed, and are currently undergoing metallurgical test work with final results pending. Results for the RC drilling, one of the diamond holes and the precollars of the three other diamond holes have been received. Significant intersections greater than 5 gram x metres are provided in Table 1 and pending results of the three diamond holes are expected during March. The RC drilling targeted a number of selected lodes with step out extensions both along strike and down dip. The Central Zone has been extended 50m to the west and remains open (Figure 1). An intersection of 5m @ 2.03g/t was intersected in MLRC255, a 50m step out to the west of the current resource in the Mallina Central Zone. Together with intercepts such as 5m @ 1.51g/t Au in lodes to the southeast of the Alfred-Argyle workings, these holes and planned follow up drilling is expected to add to the current Mallina resource base. The step out diamond drill holes targeted both deeper down dip extensions of the previously intersected wide alteration and gold zones on section 609315E and known mineralised lodes for metallurgy test work. MLRC259D is an 80m step-out below the broad 50-70m wide alteration zone previously intersected (and reported) in MLRC214D (56m @ 3.04g/t including 30m @ 5.29g/t) and 50m below MLRC215 (16m @ 3.00g/t including 6m @ 4.66g/t). Logging of this new hole shows a similarly wide 50-70m alteration zone, including sulphides and limited quartz veining (Figure 1). Assay results are pending for this hole. | |
