- Nine holes now outline two productive fault splays at
West Fault Complex - Six holes completed to depth intersected breccia/fault/vein zone with siderite-galena-sphalerite mineralization
- West Fault target remains open along strike in both directions and down dip, only 200 metres of the 1,100 metre-long structure having been tested
- A possible southwest oriented high-grade silver high-grade shoot direction has now been revealed
The 8,579 hectare Haldane Property is located in the western portion of the
“In our two drilling campaigns over the past 12 months at Haldane, we have discovered and started to define high-grade silver bearing veins within the

(1)True width of the vein and breccia mineralization is estimated to be 50-70% of the core length intersection. A value of 60% is used for the purposes of reporting HLD21-26, 27.
(2)Silver-equivalent values are calculated assuming 100% recovery using the formula: ((20 * silver (g/t) / 31.1035) + (1650 * gold (g/t) / 31.1035) + (0.90 * 2204 * lead %/100) + (1.10 * 2204 * zinc %/100)) *(31.1035 / 20). Metal price assumptions are
US$20 /oz silver,US$1650 /oz gold,US$0.90 /lb lead andUS$1.10 /lb zinc.(3)Core recovery is estimated at 69% for HLD21-26 and 94% for HLD21-27 over the reported intervals.
HLD21-26 intersected the West Fault structure at 268.43 m over a core length of 15.42 m (estimated true width of 9.25 m), exhibiting good strength and width. Strong siderite/sulphide breccia and veining was intersected at 270.41 m returning a 5.09 m (3.05 m estimated true width) intersection of 205 g/t silver (369 g/t silver-equivalent). The highest grade interval of 0.55 m (0.33 m estimated true width) of 437 g/t silver, 9.99% lead and 16.9% zinc (1,383 g/t silver-equivalent) consisted of very strong siderite-galena-sphalerite with trace tetrahedrite in veins and breccia. Siderite/sulphide veining is bounded on both sides by zones of clay-gouge with elevated silver content.
HLD21-27 intersected the West Fault structure at 222.40 m over a core length of 16.75m (estimated true width of 10.05 m). Strong siderite vein and vein breccia with banding open-space fill textures was intersected at 225.00 m, returning an 8.00 m (4.80 m estimated true width) intersection of weakly mineralized material grading 81.4 g/t silver (113 g/t silver-equivalent). This intersection expanded vein mineralization at the West Fault 50 m to the northeast along strike from HLD20-19 that intersected 8.30 m (4.48 m estimated true width) of 444 g/t silver (554 g/t silver-equivalent). Although the vein and vein breccia was wide and consisted of textures associated with productive mineralization, it was moderately to strongly oxidized with remnant sulphides occurring predominantly as disseminated blebs indicating a lower overall original galena and sphalerite content.
Holes HLD21-26 and -27 intersected the upper WF2 vein. Our current interpretation is that a “step over” from the WF1 vein to the WF2 occurs in the vicinity of the HLD21-24 and -25, where the width and grade of the vein is the strongest. The orientation of the step over is not definitive, but one possibility is that it plunges steeply to the southwest in the plane of the
Our current level of understanding indicates that stepping out along strike to the southwest and down dip along the structure from HLD21-24 and -25, where our highest grades and thicknesses of veining to date have been intersected, is most prospective. However, the possibility still remains that stronger mineralization may redevelop along strike to the northeast of HLD21-26, and -27 where in excess of 350 m of structure remains open.
