Aftermath Silver Ltd. provided assay results from its Phase 2 diamond drill program at the Berenguela silver-copper-manganese deposit located in the Department of Puno in southern Peru. Results are included for another 23 holes from the planned 60-hole (4,600m) program of diamond core drilling. Additional holes will be released pending overlimit check assays.
Highlights of the current drilling include: AFD071 intersected 23.6m @ 319g/t Ag + 2.19% Cu + 17.43% million from 2.6m down hole. AFD109 intersected 27.4m @ 187g/t Ag + 0.97% Cu + 5.13% million from surface including an intercept of 5.6m @ 410g/t Ag + 1.21% Cu + 5.81% million from 10.45m downhole. AFD111 intersected 10.1m @ 273g/t Ag + 0.90% Cu + 4.11% million from surface.
Drilling was carried out at a high angle to mineralization controls and intersections are assumed to equate to true thickness. Drill sections are available on Aftermath's website or by clicking here. The weighted average core recovery in the mineralized intersections was 92%.
Some lower recoveries were returned close to surface (0 to 5m) in initial drilling runs, and around some underground workings. Holes AFD064 to AFD077 targeted the transition zone between Domain 1 to the west and Domain 2 to the east, a structurally complex zone with faulting parallel to section lines. Drilling was designed to aid in the structural interpretation of the area and increase indicated and/or measured resources where appropriate.
Holes AFD105 to 107 and AFD108 to AFD113 were drilled in the eastern synform and antiform (respectively) and were designed to extend and define the margin of mineralization whilst converting inferred resources to indicated and/or measured categories where appropriate. The host stratigraphy at Berenguela comprises folded thickly bedded, light grey limestones and dolomitized limestones. Several large bodies of black massive, patchy, and fracture-controlled manganese oxide replacement mineralization with associated silver, copper, and zinc enrichment, occur in the folded limestones.
Mineralization largely follows stratigraphy and is typically conserved as eroded synform or antiform remnants, usually exposed at surface and with fold axes trending 105-120 degrees. The limestone is underlain by a transitional arenite unit overlying evaporites in footwall formations. Historical mapping and resource modelling shows the mineralization to extend for roughly 1,300m along strike - including a previous 100m gap or discontinuity now closed by drilling announced in this release - with a width of 200 to 400m.
The drilling was carried out at a high angle to the stratigraphically controlled mineralization and intersections are approximately true thickness.
