SLAM has completed bulk sampling of the Maisie gold vein for the season. The bulk sampling program focused on two high grade shoots known as the “Hook“ and the “Blow“. After digging with an excavator, Gold-bearing quartz was dug with an excavator, passed through a jaw crusher then ground in the hammermill to a fine sand and through a 0.8 mm screen. The material was then passed over two shaker-tables.

During initial operations at the Hook in September, material was pre-crushed by a local contractor but this method resulted in dilution of the high grade material. In October, the Company incorporated its new jaw crusher into the system and began processing high grade gold-bearing material from the Blow.
After proceessing approximately 40 tonnes of vein material, the Company submitted 2.1kg of gold concentrates to General Refining Corporation (“GRC”) of Brampton, Ontario for testing and refinement. The refinery produced 298.28 grams (9.8 oz) gold and 30.79 grams (1.0 oz) silver from the concentrates. Recovery rates were 98% and 90% for gold and silver respectively. After deductions by the refinery, SLAM was paid a net amount of $14,541 for the contained gold.

The Company proposes to extract 2,000 tonnes from the high grade gold vein using an excavator. No drilling or blasting is required for this program. The extracted material will be processed using gravity based equipment to separate the gold. No chemicals will be used in the process. The purpose is to develop environmentally sustainable techniques to extract gold, provide an estimate of the grade of the Maisie vein and demonstrate whether these veins can produce enough revenues for longer term mining operations.
SLAM is finding bonanza gold at surface through cost effective and time-tested prospecting and trenching techniques. The initial discovery was the Maisie zone, where approximately 15 sites of visible gold were discovered along the 700 m strike length of the zone during the 2012 trenching program. Some of these sites represent bonanza grade shoots within the Maisie vein system. Five diamond drill holes have intersected bonanza grades to a depth of 30m containing up to 131 g/t gold over 0.31 m. The vein system and bonanza shoots are open at depth.
Company management recommends another stage of drilling to test this gold deposit to the 100 m depth with potential to go much deeper. This type of “motherlode” vein system often runs very deep and has potential for a long term mining operation as this emerging gold play evolves.
The Maisie zone and Zone 9 are both bedrock-hosted vein-type gold occurrences and are depicted as yellow stars on this contour map. A third star near the east edge of the soil anomaly represents a cluster of gold-bearing gold boulders that suggest a potential extension 2.5 km along strike from the Maisie zone. A gold-bearing boulder shown as a yellow star 5.7 km northwest of the Maisie zone near the west edge of the soil anomaly probably derives from a separate vein system. The 3 yellow diamonds near the west edge of the map represent base metal-silver skarn deposits also within SLAM’s extensive Menneval claim holdings.
Since launching its initial diamond drilling program in December 2012 SLAM has put down 64 diamond drill holes for a total of 2178 m in 2 separate campaigns. The systematic drilling program traced the Maisie gold bearing vein system to a depth of 30 m. The trenching program had already established a strike length of at least 700 m. Drill setup locations were controlled with a grid at 40m line spacings as shown on the Drill Hole Location Map below. The set-up locations are shown with each hole location indicated by text. The target quartz vein trace is shown as a blue line. Selected high grade to bonanza grade gold-bearing sites discovered in the trenching program are shown as green diamonds. The typical drilling pattern has 3 holes drilled from each setup at angles of 45, 60 and 70 degrees respectively.
Gold-bearing quartz veins occur in 57 of the 64 holes over core intervals ranging from 0.1m up to 9.7 m. Visible gold was noted in 8 holes MG1201, MG1211, MG1221, MG1224, MG1225, MG1226, MG1352 and MG1363. Grades range up to 121.00 g/t gold over 0.31 m and 22.97 g/t gold over 1.9m. The diamond drilling program followed up the successful trenching program that sourced the Maisie discovery boulders to bedrock and exposed a gold bearing quartz vein over 700 m strike length.
The trenching program indicated numerous sites of visible gold shown as green diamonds on the map below. These visible gold sites are supported by assays ranging up to 1980 g/t gold. The selected gold values represent measured channel and chip samples as well as grab samples reported by news releases October 24 and November 14, 2012. Highlights include an area with chip samples ranging up to 1100 g/t gold over 1.1 m and channel samples up to 211 g/t gold over 0.5 m near the center of the vein system on grid line L4480E. SLAM established a grid with lines spaced 40 m apart and picket sites at 20 m intervals to provide detail control over trenching and drilling.
Other targets include Zone 9 where a series of trenches have unearthed a swarm of crosscutting quartz veins located 700 m south of the Maisie Zone shown on the map to the right. These veins are mineralized with minor limonite, goethite, hematite and pyrite similar to accessory minerals in the Maisie vein and range up to 1.2 m in thickness. Trench Men12-11 uncovered quartz boulders with visible gold 2500 m east of the Maisie zone. These boulders are similar to the Maisie vein and the Company plans additional work to find their source.
SLAM’s Menneval property is shownaon the aeromagnetic gradient map to the left. The property comprises 8 contiguous claims covering 12,000 hectares of favourable meta-sedimentary rocks. The pink and red background areas represent magnetic highs on this aeromagnetic map. New gold-bearing boulder occurrences are shown as as green diamond symbols. Company geologists also found a quartz boulder grading 1.54 g/t gold that appears to represent a separate vein structure located 5700 m to the north. The 3 green stars near the left side of the map represent skarn deposits drilled by previous workers in exploration programs dating back to 1965. The 3 zones have been tested by approximately 27 diamond drill holes for a total of 4850 m. The most significant intercept was 0.57% copper over 17.5 m drilled in 1973. Reported higher grade intercepts include 2.20% copper + 1.88 opt silver over 0.76 m and 8.86% copper + 4.15 opt silver over 0.6 m.
