Re: News - Tuesday, January 08, 2013 Title: Masuparia Provides Update on Bulk Sample at Greywacke
NR: 13-01
Masuparia Gold Corporation (TSX.V: MAS) ("the Company" or "Masuparia") is pleased to report on progress made regarding the Greywacke North deposit evaluation program. The Greywacke project is part of the LRSG JV between Masuparia and Golden Band Resources Inc. (TSX.V: GBN; OTCQX: GBRIF) ("Golden Band") with MAS acting as the operator during the exploration phase.
On December 20, 2012, the JV received the necessary approvals to collect a surface bulk sample from the Greywacke North deposit. The objective of the bulk sample program is to gather an understanding of how the Greywacke ore will process and recover through the nearby Jolu mill which is owned and operated by Golden Band and located 50 kilometres north of the deposit.
In preparation of this bulk sample, the road access to site was improved, a detailed fall program of channel sampling, verification of historic core and drill hole locations and sampling of existing core and preservation of historical drill core was completed (see news release of December 5, 2012). Under the direction of Golden Band, Taiga Consultants Ltd. collected mineralized core specimens and delivered them to Michael Yakimchuk, metallurgist for Golden Band, for advanced metallurgical testing by Saskatchewan Resource Council (SRC) prior to the bulk sample program. In addition to assaying, the material was subject to total digestion ICP analysis.
Selected analytical results are presented below:

5,990 | This work confirms a low sulphide content and a weak positive correlation of gold to elevated Pb, Zn, S and Ag.
Two composite samples were delivered to the facilities of SRC in Saskatoon for bench scale metallurgical work as designed by Golden Band and the SRC. We are pleased to report the results of this test work as applicable to utilizing the Jolu mill for processing:
- Gold recovery of over 93% was achieved when simulating Golden Band's current processing circuit.
- An average of ~80% of the gold was recovered using gravity concentration techniques, based on the processing of multiple samples.
- It was observed that Golden Band's current grinding and leaching circuit is suitable for achieving high gold recoveries.
- Calculated feed grade of the samples delivered to the bench scale circuit ranged from 7.4 g/t to 8.0 g/t
The summary excerpt from the "Final Report Lab Scale Test for Gold Recovery Prepared by Saskatchewan Research Council SRC Publication No. 13455-1C12" is quoted below:
- Metallurgical testing sample #1 was made from the samples in pail #1 and pail #2. Metallurgical testing sample #2 was made from the samples in pail #3 and pail #4.
- Direct head assays indicated 5.4 ppm gold in sample #1 and 6.0 ppm of gold in sample #2 while the calculated head grades were 7.4 ppm for sample #1 and 8.0 ppm for sample #2. The discrepancy between the assayed and calculated head feed gold content indicates the existence of gold nuggets in the samples. It is difficult to get representative samples for direct head assays when gold nuggets in the samples.
- There were 17.8% and 17.4% over 150 mesh samples produced when the sample #1 and #2 were primary milled to 70% passing 200 mesh, respectively.
- The gravity separation using a MD-3 Knelson Concentrator was effective for the Golden Band samples. Of the total gold in the gravity separation feed, 93.4-93.6% gold was recovered.
- Cyanidation recovery was 77.2% for sample #1 and 91.1% for sample #2. The discrepancy was likely caused by the errors of gold analysis.
- The overall gravity recovery was 83.1% for sample #1 and 76.5% for sample #2 based on the direct feed assay.
- The bond ball mill work index was 17.28. The sample was moderately hard rock.
These bench scale results were very favourable to the processing of this material through the Jolu mill. The poor correlation between repeat assays and the high percentage recovery of gold by gravity points to a nuggety nature of the gold distribution in the La Ronge Gold belt. To confirm and to better assess the mineralized material, a bulk sample in the order of 15,000 tonnes will be toll milled this winter.
Upon completion of the bulk sample a winter drill program is scheduled for the Greywacke North deposit to increase the confidence in the potential open pit portion of the deposit and test deeper extensions. This work will support the completion of a preliminary economic assessment (PEA) of the deposit.
In preparation of future production from the Greywacke deposit, the JV is completing baseline environmental studies necessary for full environmental permitting. The fall study has been completed through the services of Canada North Environmental Services Limited Partnership; the winter study has been authorized and is scheduled for January 2013 and the spring and summer studies are planned for later in the 2013 calendar year.
