Niblack Mineral Development along with the Heatherdale Resources, have reported the further encouraging results of the exploration and definition holes, drilled during the summer and spring campaign at the Niblack volcanogenic massive sulphide (VMS) project, southeast Alaska.
Niblack Project - 2011 Surface Drilling
The company has intersected 4.66% copper, 13.57 g/t gold, 302 g/t silver and 15.26% zinc over 26.8 ft in the hole U131, 2.54% copper, 5.54 g/t gold, 126 g/t silver and 10.96% zinc over 44.6 ft in the hole U132 and 4.60% copper, 5.68 g/t gold, 141 g/t silver and 10.00% zinc over 35.7 ft in the hole U136.
Niblack employed three drilling rigs to drill 21,300 ft. Two underground rigs were always active during the campaign, for discovering and outlining the resources at the Trio and Lookout zones. Many holes were aimed at the sample compilation for metallurgical test work. A helicopter-borne surface rig was used during the drill program in order to examine numerous convincing exploration targets in the previous Niblack Mine, the Broadgage and Trio zones.
The strength of the mineralization at the deposit has been confirmed by 10 definition holes, drilled at the Lookout zone. Drill core from this campaign will be used to progress the understanding of the project metallurgy.
Three exploration holes drilled using underground rigs has set the mineralization continuity that houses felsic horizon between the Trio and Lookout zones and to the Lookout zone’s northwest part. These holes have offered encouraging signs for the next drilling phase in these regions.
Six surface exploration holes out of seven examined the felsic prospect at the Trio-Broadgage region and one hole focused the nearby region of the previous Niblack Mine. This drill program has confirmed the comprehensive geologic model. Six holes out of seven have cut sulphide mineralization. This hole S148 discovered the mineralization, including 1.54 g/t gold and 0.53% copper over 22 ft.
