RED CLIFF PROPERTY

Overview

The Red Cliff Property, a Gold/Copper property in the “Golden Triangle” area of northwestern British Columbia, is owned 35 % by Mountain Boy Minerals Ltd. On November 19, 2008, the Company entered into an option agreement with Decade Resources Ltd. (Decade), a company with shared Directors, to allow Decade to acquire a 60% interest in the property. Decade Resources Ltd. then fulfilled all requirements to earn its 60% interest in the property. Subsequent to this initial interest, Decade acquired a further 5 % and now owns a 65 % interest, with Mountain Boy Minerals owning the other 35 %. The property consists of 8 Crown Granted claims along Lydden Creek, just north of the town of Stewart, B.C. It is accessible by road approximately 1.5 kilometers from paved highway 37A and is underlain by lithologies of the middle Jurassic Hazelton Group. These rocks host significant precious and base metal deposits in the Stewart Camp including the Silbak Premier, Silver Coin, Sulphurets, Red Mountain, Scottie Gold and Eskay Creek deposits.

To date, 2 main mineralized zones; the Redcliff copper-gold and copper zones as well as the Montrose gold zone have been outlined.

The Redcliff Zone contains 2,300 m of underground development on 5 levels from 4 portals over a height of several hundred meters with limited Cu-Au production reported in 1910-12 and in 1973. From 1910-12 production from the Redcliff zone amounted to approximately 1,136 tonnes estimated to average 5% Cu. In 1972 some 3,776 tonnes of ore was sent to a local mill. The only reserve estimate reported for the Redcliff Zone was in 1912 showing a total of 18,900 tonnes averaging 3.19% Cu and 2.86 grams per tonne gold. This estimate was only for broken mineralized material within a stope on one of the levels in the mine. This estimate is historical and is not 43-101 compliant and is used for reference purposes only.

On the Montrose zone during 1939-41, there was 65 tons mined averaging 2.45 opt Au, 2.95 opt Ag, .91% Cu, 3.5% Pb and 4.41 % Zn.

Work in the area of high grading during a previous operator’s sampling program in 1979 yielded 19.31 g/t over 2.43 m and 1987 surface sampling gave 7.93g/t over 3.81 m. Several holes drilled in 1988 to 1990 gave intercepts of 1.72 g/t over 14.48 m including 9.31 g/t over 1.70 m and 1.17 g/t over 16.89 m including 4.82 g/t over 2.29 m.

In 1988 the Waterpump Zone which represents the south fault extension of the Montrose Zone was discovered. It is located approximately 50 meters south of the 1939-1941 mining. A trench over the zone gave values consisting of 21.37 g/t over 4.2 m and 6.89 g/t Au over 3.3 m with 2.0 m of dyke between the values. Across the entire zone including the dyke, the sampling yielded an average of 12.07 g/t Au over 8.5 m.


The original Red Cliff property is a former producing copper and gold property originally staked in 1908 located about 20 kilometers north of Stewart, British Columbia in the Skeena Mining Division. It consisted of 8 Crown Granted claims along Lydden Creek. The Crown Granted portion of the joint venture project is now owned 65% by Decade. The Company has identified 4 separate gold bearing zones called the Red Cliff, Upper Montrose, Lower Montrose and Waterpump within the Crown Granted claims.

The claim group extends from just west of American Creek with its confluence with Bear River along Lydden Creek for approximately 3 kilometers as well as for 5 kilometres along the west side of American Creek. The east side of the property is accessible by drill roads approximately 1.5 kilometers from paved highway 37A. It is underlain by lithologies of the middle Jurassic Hazelton Group. These rocks host significant precious and base metal deposits in the Stewart Camp including the Silbak Premier, Silver Coin, Sulphurets, Brucejack Lake, Big Missouri-Martha Ellen, Red Mountain and Eskay Creek deposits.

The Crown Granted portion of the property contains six different mineralization types identified in the exploration activities. Mineralization noted in the zones is as follows:

Highlights from historical work for the three of the zones on the property include:

In the period from 2007 to 2018, a total of 74,020 meters of BTW and NQ size drilling in 409 holes on drill roads constructed during the various field seasons. Drilling was primarily conducted in the area of the Red Cliff zone and Montrose zones. The holes on the Red Cliff zone were drilled in order to test below and west of the underground working. Drilling extended the zone well below the lowest working as well as indicating that 4 separate zones of copper and copper–gold mineralization are present along a wide structure. Drilling on the Montrose zone was conducted in order to define the limits of mineralization within the zone.

The drilling to date for the Montrose zone at the Red Cliff property has allowed for a preliminary characterization of the mineralized system as follows:

Property mineralization intersected to date indicates that the gold-bearing system is open along strike and to depth. The system has characteristics of a mesothermal, or deep-seated system, and as such can be expected to have significant depth continuity in addition to the along-strike continuity which is being shown by drill results. The width of the hosting structure, presence of high grades of gold, zones of stockwork mineralization peripheral to the vein-hosted gold and associated sulphides, and depth extent shown by drilling, indicate significant untested potential within this large system.

Metallurgical studies indicate gold recoveries of 94.8% and 97.6%, respectively for 2 separate composites of core samples from Red Cliff DDH-12-MON-61. Samples were from cut core and included the interval from 173.93 to 190.24 m (Red Cliff #1) and 200-208.99 m (Red Cliff #2). Within the intervals, gold is associated with sphalerite-galena stringers as well a separate pyrite-chalcopyrite stockwork. A summary of the work by SGS Minerals Ltd is quoted below:

“Gravity tests were conducted on the two composites by passing the ground pulp to a Knelson concentrator followed by Mozley table upgrading. The composites responded well to gravity concentration and 54.2% and 78.2% of gold on average were recovered into gravity concentrate at 447 g/t Au and 1618 g/t Au grade respectively for Red Cliff 1 and Red Cliff 2.

Batch cleaner flotation tests were performed on whole ore from the two composites to produce a Cu-Pb bulk concentrate and a zinc cleaner concentrate. The composites responded well to conventional flotation. For Red Cliff 1, the Cu/Pb bulk cleaner concentrate assayed 25.8% Cu, 7.86% Pb, 4.12% Zn and 323 g/t Au at recoveries of 88.1% copper, 79.2% lead and 81.7% gold. For Red Cliff 2, the concentrate assayed 25.7% Cu, 6.98% Pb, 3% Zn and 256 g/t Au at recoveries of 93.1% copper, 67.1% lead and 76.0% gold. The results were achieved from batch cleaner tests and the recoveries will be higher when locked cycle flotation tests are conducted. Optimization is needed to improve zinc flotation for both composites.

Pre-concentration and flotation tests were performed on the two composites and very good results were obtained. The copper grades were 25.2-25.4% at recoveries of 80.8-81.9%. The lead grades in the bulk cleaner concentrates were 6.95-8.58% at recoveries of 66.6-71.5%. The combined Pb recoveries (gravity + flotation) were 76% and 83.1% respectively for Red Cliff 1 and Red Cliff 2. Gold recoveries were high for the two composites and the total gold recoveries (gravity + Cu-Pb Conc) were 90.4% and 96.4% respectively for Red Cliff 1 and Red Cliff 2. The zinc rougher tailings were subjected to cyanidation and additional 4.4% and 1.2% of gold were leached out. The overall gold recoveries were 94.8% and 97.6%, respectively for Red Cliff 1 and Red Cliff 2.”

Due to the steep nature of the hillside, future work should include creation of underground drill stations to further explore the mineralized system.
