AURORA DRILLING UPDATE, 64NORTH PROJECT (SEPT 17)

 

READ THE FULL ASX RELEASE

 

“"We are pleased to see this shallow dipping 7m thick quartz vein with considerable sulphides present as part of a broader 22m thick zone of interest. While the presence of gold won’t be known until the assays are returned, we know in a Pogo-style system there can be large variations in grade and vein thickness within short distances and it is important to drill more holes into this immediate area to test for grade variation, lateral extents of the vein and possible stacked sets nearby."”

-Managing Director Duncan Chessell

 

EXECUTIVE SUMMARY:

  • Drilling has been completed at hole #7 (20AU07) to 712m depth at the Aurora Prospect. The hole was designed to test a high priority target with a planned depth of 600m.
  • Encouraging shallow dipping 7m thick quartz vein intersection from 488m in hole #7 as part of a 22m thick zone of intense sulphides, alteration and quartz veining from 476m.
  • Selective samples have been submitted on priority order to laboratory - expected results in less than one month.
  • Currently planning to drill a fan of holes from same drill pad as 20AU07.
  • All-year road access allows drilling to continue through winter.
  • Camp change-over to winter quarters required to prepare for winter drilling and the company will update investors as timeline for resumption of drilling is confirmed at the Aurora Prospect.
  • Fully funded drilling with news flow for the remainder of 2020.

 

 

Resolution Minerals is pleased to update investors with visual drilling results for hole ID:20AU07 (Holes #7) at the Aurora Prospect and that the third phase of drilling for 2020 is complete on the West Pogo Block adjacent to Northern Star’s (ASX:NST) Pogo Gold Mine, Alaska.

Drilling production rates have improved throughout the year and high-quality structural data has been collected from orientated HQ core. The structural information learnt from the drilling is crucial in unlocking the structural controls on mineralisation and will be combined with assay data when it becomes available to enhance drill targeting.

The Aurora Prospect is road accessible, which allows for year-round drilling. The current summer camp will be demobilised shortly, after the summer regional program is completed and a winter suitable camp will be installed to facilitate continued drilling. Once firm timelines are established the Company will update investors with expected date of resumption of drilling and further pertinent details. An operations update on the Boundary Prospect and other aspects of the 64North Project will be dealt with in a separate operations update, likely next week.

 

Hole ID: 20AU07 – Aurora Prospect – completed to 712m

A track mounted diamond core drilling rig has completed the third diamond core hole at the Aurora Prospect for this phase of drilling (hole ID:20AU07). The hole was extended 112m and drilled to 712m depth and was designed to test a NE trending structural zone. The hole is located on the central-northern edge of the Aurora prospect, proximal to an outcropping diorite intrusive and coincident with conductive rocks identified by the CSAMT and ZTEM geophysics surveys. Production rates were good with average of > 70m/day and good quality orientated core data is being collected as the hole is being logged in detail.

 

Geology

The quick log completed in the field indicates hole#7 intersected predominantly biotite-quartz-feldspar-gneiss (BQFG) “para-gneiss” which is the typical host rock at the Pogo Gold Mine. The hole also intersected narrow altered intrusive rock units, granites, minor breccias, fault gouge zones and higher in the hole minor intervals of orthogneiss. The sulphides from 476m-498m, are typical of an Intrusion Related Gold System (IRGS) and Pogo-style system being: arsenopyrite, pyrite, pyrrhotite and additionally minor fuchsite (chrome mica). Significant sericite, chlorite and dolomite alteration was also observed to account for the conductive rock units predicted by geophysics surveys (CSAMT and ZTEM). It appears that the structural dilational event which gives rise to the space required for thick sulphide bearing quartz mineralisation to occur has “popped open” in this central-northern edge of the Aurora Prospect. This dilational event was the missing ingredient from the other zones tested to date on the Aurora Prospect. The nearest holes are 670m to the west (hole#4) and 950m to the east (hole#3) and we believe there is significant exploration space to warrant a concerted effort at this “hot zone”.

 

Resolution cautions that a 7m thick quartz vein with sulphides present is not evidence of the presence of gold. While we don’t see visible gold in this interval we understand that in a Pogo-style system there can be large variations in grade and vein thickness within short distances and it’s important to drill more holes into this immediate area to test for: grade variation, lateral extents of the vein and possible stacked sets nearby. The Company firmly believes further drilling from this location in a fan of drill holes is warranted.

The Pogo Gold Mine is published to be “quartz hosted stacked vein systems (Liese, Fun Zone, South Pogo, East Deeps) at Pogo are flat to moderately dipping (25-45°) laminated to massive veins dipping towards the NW and vein width varies from <0.5m to >10m (average ~3m)” and “Sulphide associated gold occurs as disseminated sulphides or in sulphide veinlets. Low sulphide content (3%)”, reference - ASX Announcement “Pogo Site Visit” Northern Star (ASX:NST) 19 September 2019
