Pure Gold Mining drills 1.8 m of 14.6 g/t Au at Madsen

2014-10-23 06:42 ET - News Release

Mr. Darin Labrenz reports


Pure Gold Mining Inc. has provided an update regarding the exploration program at its 100-per-cent-owned Madsen gold project in the prolific Red Lake gold district of Northwestern Ontario. The $4.0-million exploration program, which includes 9,000 metres of diamond drilling, is designed to test and expand the current mineral resources(1), while concurrently developing and drill testing high-grade, 8 zone-style targets through continuing evaluation of the large historic database.

Phase I of the exploration program is currently focused on near-surface high-grade mineralization along the 12-kilometre-long Madsen mine trend, which includes the Madsen mine, Red Lake's second-largest past producer with over 2.4 million ounces produced. Initial target areas include McVeigh ramp, Fork zone, Junction and Point. Phase II, to begin in the winter months, will focus on targets along the 10-kilometre-long ultramafic contact, including Russet South.

Highlights from the continuing exploration program include:

  • Approximately 4,000 metres in 12 diamond drill holes have been completed to date testing the McVeigh ramp, Junction and Fork zone target areas. Assay results from the first seven drill holes are reported here, with results from the remaining five holes pending.
  • Drilling in the Fork zone has identified a silicified feeder structure that has been delineated for approximately 275 metres along strike and to a depth of 200 metres. Assay results are reported from the initial three holes and include 14.6 grams per tonne gold over 1.8 metres from hole PG14-006 which contains visible gold.
  • Drill holes PG14-009 and PG14-011 also contain visible gold. Assay results are pending from drill holes PG14-008 through to PG14-011, which intersected the silicified structure in Fork zone.
  • Limited drilling at McVeigh ramp intersected multiple mineralized horizons of garnet and biotite alteration representing the McVeigh, Austin and South Austin horizons. Significant assays include 8.3 grams per tonne gold over two metres and 5.3 grams per tonne gold over five metres.
  • Structural and alteration mapping, soil and rock geochemical sampling programs completed at the Fork zone, Junction, Point and Russet South target areas continue to advance new drill targets.

"The application of modern exploration techniques are already leading to an improved understanding of the geology and delivering outstanding new targets at the Madsen gold project," stated Darin Labrenz, president and chief executive officer of Pure Gold. "Our initial drilling in the Fork zone has identified a gold-bearing structure that has been targeted and traced for approximately 275 metres. Modelling of this structure and the recognition of the related folded mafic-ultramafic contact has defined a shallow southerly plunge control to higher-grade mineralization. The intersection of this structure and the ultramafic contact has been identified as an exciting new target. We look forward to testing this target in the coming months when access will be facilitated by winter freeze-up."

Reported results

Fork zone target

Pure Gold has completed seven drill holes in the Fork zone utilizing oriented core to identify a previously unrecognized fold in the mafic-ultramafic volcanic stratigraphy. The fold is associated with a steeply dipping, north-south-striking silicified structure with chlorite-garnet-magnetite-biotite alteration and anastomosing grey quartz veinlets that host specks of visible gold. Folding of the stratigraphy in conjunction with the associated silicified structure imply a shallow, southerly plunge to high-grade intercepts in the Fork zone.

The high-grade silicified structure ranges from one to two metres in true width, has been traced for approximately 275 metres in strike length to a vertical depth of 200 metres, and visible gold has been identified in three drill holes (holes PG14-006, PG14-009 and PG14-011). Assay results for PG14-006 are reported in the associated table. Other results are pending.

(i) Assay composites were calculated using uncut assays and 
are reported as drilled widths and interpreted to vary 
between 85 per cent and 95 per cent of true widths.

The silicified structure has been identified in surface outcrop and is open to depth and along strike. Initial modelling of the structure by Pure Gold highlights where the structure could potentially intersect and thicken at the Russet ultramafic contact and/or the Balmer-Confederation unconformity. This area is currently being sampled by MMI soils to assist in target delineation and will be further drill tested following winter freeze-up.

McVeigh ramp target

Pure Gold completed three drill holes in the McVeigh ramp targeting extensions of the McVeigh, Austin and South Austin mineralized horizons at the southern boundary of the historic mine workings.

All three drill holes successfully intersected the McVeigh horizon but the up-dip extension of historic drill hole 4M-224 (5.6 metres grading 26.4 grams per tonne gold(1)) could not be tested from the current drill site due to surface conditions and the proximity to the ramp and other underground workings. This potential high-grade mineralized shoot will be tested after the completion of the Fork zone drilling.

PG14-004(ii)         abandoned

(i) Assay composites were calculated using uncut assays and may 
include internal dilution. Composites are reported as drilled 
widths and interpreted to vary between 70 per cent and 95 per cent
of true widths.
(ii) Hole PG14-004 was abandoned at 84 metres after intersecting 
underground workings prior to reaching target depth.

Drill hole PG14-002 intersected all three horizons returning 5.3 grams per tonne gold over five metres from South Austin and 8.3 grams per tonne gold over two metres from the Austin horizon approximately 50 metres up dip of historic mine workings. Geological modelling and collection of oriented drill core continue to develop a better understanding of high-grade controls on mineralization, and additional targets will be drill tested later in the drilling campaign.

Exploration drilling targets

Junction target

Structural mapping and regional MMI soil sampling recently completed at the Junction target have highlighted the potential of this target. Additionally the high-grade gold mineralized structure identified at the Fork zone has now been traced toward the Balmer-Confederation unconformity in the Junction area where historic drill hole ST-10-33 returned seven grams per tonne gold over two metres(1). An 80- to 100-metre-wide zone of strong biotite-garnet alteration occurs along the unconformity in this target area, and Pure Gold believes that this structural intersection provides high potential for increased thickness of the high-grade mineralization identified at the Fork zone. Pure Gold has targeted the area with an initial drill hole designed to intersect the unconformity and the altered zone on the Balmer assemblage side of the contact. Assay results are pending. The target area has historically been underexplored, and provides an opportunity to define and extend Austin zone mineralization along the unconformity more than one kilometre south of the Madsen mine development.

Point target

The Point target was identified by surface mapping in July, 2014, which outlined a thickened zone of biotite-garnet alteration associated with a sinistral jog in the unconformity, corresponding with historically mined stopes of the Austin zone at depth. Follow-up detailed mapping at this target in August and September identified a strong shear zone axial planar to this sinistral jog, now positively identified as a D2 fold. MMI soil sampling in the vicinity returned high copper, lead, zinc and elevated arsenic pathfinder elements in the vicinity. Planned drill holes at the Point target have now been refined based on this new mapping and will test this deformation zone, known as the Pumpshack shear. Pure Gold is testing this prospective, near-surface hydrothermal alteration and structural deformation with the goal of identifying mineralization similar to the Austin zone, which was mined at depth below 10 level.

Russet South target -- 8 zone up dip

The Russet South target is located approximately 1,400 metres west of the Madsen shaft, and approximately 1,600 metres up-dip of the 8 zone resource. The target lies on the western flank of the Russet ultramafic contact and was explored historically in 1944-1947, 1968, 1974 and 1987-1988 prior to consolidation of the property. This historic work highlights the potential of the target to produce high-grade gold-bearing alteration. Several zones of strong alteration characterized by carbonatization, biotitization, quartz veining and pervasive silicification have been recognized at surface where they associated with intense shearing. Historic drill results at the target area include 0.7 metre grading 63.77 grams per tonne gold from hole 87, four metres grading 14.40 grams per tonne gold from hole UBT-88-48 and 0.8 metre grading 78.38 grams per tonne gold and 0.6 metre grading 529.54 grams per tonne gold from hole UBT-88-44.(1)

Geologic fieldwork completed at the Russet South target this summer includes structural mapping, prospecting and detailed MMI soil sampling which continues to advance drill targeting and highlight the 8 zone up-dip potential of the area. MMI soil sampling identified a 700-metre-long-by-200-metre-wide plan width gold-in-soil anomaly which correlates with a mapped northwest trending shear zone, cutting refolded ultramafic and banded iron formation contacts. Outcrop grab samples from limited surface prospecting within the shear zone returned 1.65 grams per tonne, 2.39 grams per tonne and 6.14 grams per tonne gold. The shear zone and associated MMI soil anomaly are open to the northwest, where the sampling grid requires expansion, and to the southeast, where the shear zone is mapped to the edge of Russet Lake on strike with the 8 zone.

Pure Gold is currently modelling results of the 2014 summer fieldwork with the goal of drill testing the Russet South target and other ultramafic targets in the first-quarter 2015 winter drill program.

About the Madsen gold project

Owned 100 per cent by Pure Gold, Madsen is located in the Red Lake gold district of Northwestern Ontario and is over 50 square kilometres in size, which makes it the third-largest land package in the Red Lake region.

The project is host to two past-producing mines; existing mine infrastructure, including an operational headframe, a 1,275-metre-deep shaft and a permitted 500-tonne-per-day mill; an indicated mineral resource of 928,000 ounces gold (3.24 million tonnes grading 8.93 grams per tonne gold) and an inferred mineral resource of 297,000 ounces gold (790,000 tonnes grading 11.74 grams per tonne gold)(1); and, a number of highly prospective exploration targets in a geological setting analogous to other modern high-grade discoveries in the Red Lake district.

A new interpretation of the role of folded ultramafic contacts and structural controls has resulted in multiple recent discoveries in the Red Lake district, including Goldcorp's High Grade zone at the Red Lake mine complex, the Bruce Channel system at the Cochenour mine and the F2 gold system at Rubicon's Phoenix mine. The environment and mineralization at Madsen's 8 zone is similar to other recent high-grade discoveries in the district. Recent resampling of historic drilling at the 8 zone returned 38.26 grams per tonne gold over 7.5 metres (see news release dated July 7, 2014). Pure Gold believes the opportunity exists to apply modern exploration science and a new understanding of the district to achieve similar success along the ultramafic contact at the Madsen gold project.

At Madsen, the 10-kilometre-long ultramafic contact is highly prospective for additional high-grade discoveries, and numerous recent discoveries along this contact have been only partially advanced. Pure Gold is pursuing a strategy of exploring for additional near-surface high-grade mineralization along the 12-kilometre-long Madsen mine trend and the 10-kilometre-long ultramafic contact.

Quality assurance/quality control and core sampling protocols

Check samples were submitted to ALS Minerals in Thunder Bay, Ont., for sample preparation by crushing to 70 per cent less than two millimetres, rotary split off one kilogram, and pulverize the split to better than 85 per cent passing 75 microns. Sample pulps are shipped to the ALS assay laboratory in North Vancouver, B.C., for gold analysis with a 30-gram fire assay and AAS finish (code Au-AA23). Samples returning greater than five grams per tonne gold are reassayed with a gravimetric finish (code GRA21). Mineralized zones with visible gold are reanalyzed by a one-kilogram screen fire assay with screen to 100 microns. A duplicate 30-gram fire assay is conducted on the screen undersize while assaying of entire oversize fraction (code Au-SCR21). Control samples (accredited standards and blanks) were inserted on a regular basis. Results were monitored on receipt of assays by Gary Lustig, MSc, PGeo, an independent consultant to Pure Gold and a qualified person as defined by National Instrument 43-101.

The information provided herein reflects the results received by the company from seven of the 12 diamond drill holes completed to date.
