(1) True width of the vein and breccia mineralization is estimated to be 50-70% of the core length intersection with the exception of HLD21-25 where precise measurements of vein contact angles yields 62.5% of the core length intersection. A value of 60% is used for the purposes of reporting HLD21-23, 24 and 62.5% for HLD21-25.
(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 70-75% for HLD21-24 and 25, with the exception of a 0.80 metre section of HLD21-24 where recovery was zero. A value of zero was assigned to silver, gold, lead and zinc for the section of zero core recovery for the purposes of composite interval calculations. Core recovery is estimated at 46% for HLD21-23.

HLD21-25 intersected the West Fault structure at 291.5 m over a core length of 13.38 m (estimated true width of 8.36 m), averaging 220.5 g/t Ag (325.0 g/t silver-equivalent). Strong siderite/sulphide breccia and veining was intersected at 293.44 m returning a 6.83 m (4.27 m estimated true width) intersection of 363.4 g/t silver (534.2 g/t silver-equivalent). The highest grade interval of 1.6 m (1.00 m estimated true width) of 1,107 g/t silver, 3.97% lead and 3.97% zinc (1,485 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. The West Fault intersection in HLD21-25 occurs approximately 25 metres uphole from where the target was modelled to occur and it is now believed that the West Fault is a complex of faults and splays rather than a single discreet fault structure. Narrow structures hosting siderite-galena-sphalerite veinshave been intersected above the West Fault mineralization in previous holes (HLD20-19, HLD21-24) and are now thought to represent the upper splay of the West Fault, now referred to as WF2. The WF1 structure, host to the high grade silver mineralization previously released in hole HLD20-19 and HLD21-24, looks to weaken to down dip to the northwest, perhaps stepping over to the WF2 splay in this direction.
HLD21-22 and -23 were drilled to test mineralization 50 metres on strike of HLD20-19 to the southwest. HLD21-22 was lost in a fault at 116.70 metres depth. HLD21-23 successfully intersected the West Fault Vein (WF1); however, recent remobilization of the fault is interpreted to have cut the vein mineralization off, yielding a 30 cm intersection of 145 g/t silver, 0.529 g/t gold, 0.30% lead and 19.3 % Zn (925.6 g/t Ag-equivalent). It appears that some of the intersection may have been lost as the footwall contact consists of rubble and gouge. Samples from the remaining two drill holes targeting the
