Pure Gold Mining (PGM-V) July 8, '14 is pleased to announce the launch of the 2014 exploration program at its 100% owned Madsen Gold Project in the prolific Red Lake gold district of northwest Ontario. The goal of the program is to prioritize drill targets designed to expand the current mineral resource, while concurrently developing a new predictive geology model for targeting high-grade, 8 Zone-style mineralization. This program is an extension of ongoing consolidation and evaluation of the large historic database consisting of historic drill, mining and exploration results. “We are excited to kick off our 2014 exploration program, which will prioritize drill targets based on our ‘proof of concept’ exploration model,” stated Darin Labrenz, President & CEO of Pure Gold. “We intend to discover new zones of high-grade mineralization along the 10 km-long ultramafic contact within the Madsen property, which we believe has the potential to host the next multi-million ounce deposit in the Red Lake district.”
A new interpretation of the role of folded ultramafic contacts and structural controls have 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 g/t gold over 7.5 metres (see Table 1). 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.
Pure Gold’s current program will be split into two phases. Phase 1, now underway, is designed to better define drill-ready targets and generate new targets. Exploration crews have been mobilized to site and are re-logging and sampling drill core, compiling historic geologic data, conducting structural mapping, and interpreting a new airborne magnetic geophysical survey. Phase 2 will follow later in the summer and is anticipated to include a 9,000 metre drill program designed to test the initial targets generated in Phase 1.
Highlights of the Phase 1 exploration program include:
- Consolidating historic archives from former operators into a common digital platform;
- Conducting a high resolution airborne magnetic survey (complete);
- Defining sampling and assaying protocols suitable for Red Lake coarse gold;
- Prioritizing near surface drill targets designed to expand the current mineral resource;
- Developing new predictive vectoring tools for targeting high-grade, 8 Zone-style mineralization; and,
- Developing a geological “footprint” of high-grade gold zones by constructing new 3D stratigraphic, structural, and alteration models, allowing more predictive drill targeting of ultramafic contact 8 Zone-style mineralization.
Geological “Footprint” Modeling
Pure Gold has commenced a Footprint Modeling program designed to create stratigraphic, structural, and alteration models for the Madsen property utilizing the +200,000 metres of drill core available at the mine’s core farm. The overall objective of the modeling exercise is to define structural controls and alteration vectors (“footprints”) associated with gold mineralization using ultra-trace geochemistry, magnetic susceptibility, Terraspec (ASD) and XRF technologies (“lithgeochemical sampling”). This footprint modeling technique has proven successful at recent Red Lake discoveries and will be utilized when drill targeting 8 Zone-style mineralization.
To date, Pure Gold geologists have re-logged over 6,000 metres of core from seven historic drill holes completed by previous operators in 2008/2009. Initial re-logging and sampling efforts focused on underground drill core that intersected the ultramafic contact near the 8 Zone. Lithogeochemical results will be incorporated into a new 3D geological model and utilized for drill targeting.
Concurrent with the re-logging of some historic drill core and modeling, geologists are sampling mineralized zones for gold analysis as a check sampling exercise. Gold assays have been received from the initial five drill holes. Significant assay results are reported below:

All five historic drill holes were collared from 10 Level of the underground workings and targeted the Russet Lake ultramafic near the 8 Zone. Four of the holes intersected gold mineralization that successfully extended the 8 Zone by 150 metres down-plunge below the historic mine workings. Hole MUG09-08 targeted the ultramafic contact approximately 240 metres north of the 8 Zone. This drill hole was re-logged and sampled in order to collect ultratrace geochemistry outside of the mineralized zone and therefore widen the geologic footprint.
Airborne Geophysical Survey
CGG Canada Services Ltd. recently completed a 1,653 line-kilometre, helicopter-borne geophysics survey covering the entire +50 km2 Madsen Gold Project. The MIDAS high resolution magnetic survey is designed from a base layer in property-scale exploration programs. Final results have been received and are being utilized by Pure Gold’s exploration team in constructing a lithology-structural framework for the property and delineating lithological, alteration, and structural controls on gold mineralization. Initial interpretations are being incorporated in the exploration targeting process.
ABOUT THE MADSEN GOLD PROJECT
Pure Gold recently consolidated its position in the Red Lake district with the acquisitions of the Madsen Gold property and the adjacent Newman-Madsen property (see news releases dated March 4, 2014 and June 25, 2014). Together, these properties make up a 50 square kilometre land package of contiguous, patented ground, collectively known as the Madsen Gold Project. Pure Gold now holds the third largest land package in the Red Lake region.
The property is host to two past-producing mines; existing mine infrastructure including an operational headframe, a 1,275 metre-deep shaft, and a 500 tonne per day mill; an Indicated mineral resource of 928,000 ounces gold (3.24 million tonnes grading 8.93 g/t gold) and an Inferred mineral resource of 297,000 ounces gold (0.79 million tonnes grading 11.74 g/t gold)1; and, multiple highly prospective exploration targets in a geological setting analogous to other modern high-grade discoveries in the Red Lake district.
At Madsen, the 10 km-long ultramafic contact is highly prospective for additional high-grade discoveries, and numerous recent discoveries along this contact have only been partially advanced. Pure Gold is pursuing a strategy of exploring for additional near surface high-grade mineralization along the 12 km-long Madsen Mine trend and the 10 km-long ultramafic contact.

QA/QC and Core Sampling Protocols
Check samples were submitted to ALS Minerals in Thunder Bay, Ontario for sample preparation by crushing to 70% less than 2mm, rotary split off 1kg, and pulverize the split to better than 85% 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 >5 g/t Au are re-assayed with a gravimetric finish (code GRA21). Mineralized zones with visible gold are re-analyzed by a 1kg screen fire assay with screen to 100 microns. A duplicate 30g 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, P.Geo, an independent consultant to Pure Gold and a Qualified Person as defined by National Instrument 43-101.
