LONDON, UK / ACCESSWIRE / February 22, 2021 / Orosur Mining Inc. (“Orosur” or the “Firm“) (TSX:OMI)(AIM:OMI), is happy to announce an replace on the progress of Minera Anzá’s drilling marketing campaign at the moment underway on the Firm’s Anzá venture in Colombia.

Outcomes of additional 4 holes.
Diamond drill holes MAP-073, 074, 075 and 076 have been accomplished throughout December 2020 and January 2021, with the holes positioned largely to handle geological questions that have been left unanswered from older drilling campaigns by earlier firms.
Over 18,000m was drilled by Waymar Sources previous to it turning into a part of Orosur in late 2014. Subsequent work by Orosur decided that a lot of this older drilling was oriented down dip, and whereas these holes typically returned superficially enticing assay outcomes, they didn’t present sufficiently dependable geological info to totally perceive the character of the mineralisation and to permit correct concentrating on and environment friendly growth drilling.
Consequently, a lot of the Firm’s preliminary 2,300m drill program at the moment underway, was designed to reply a number of excellent orientation and structural questions and to offer perception into the model of mineralisation, with a deal with the potential for a hybrid polymetallic VMS/Epithermal mannequin.
These 4 holes have been drilled on three sections, and returned enticing gold intersections, assisted in addressing key structural questions, and returned huge intersections of high-grade Zinc that added weight to the polymetallic VMS mannequin. Key intersections embrace (full intercepts are detailed in desk 1):
MAP-073 21.60m @ 6.02g/t Au, 6.02g/t Ag and three.23 %Zn from 271.75m
MAP-074 5.20m @ 1.17g/t Au 4.97g/t Ag and three.02% Zn from 195.40m
MAP-075 19.85m @ 0.90g/t Au 2.17 g/t Ag and 6.46% Zn from 226.15m
MAP-076 12.25m @ 5.39g/t Au, 1.65 g/t Ag and 0.18 % Zn from 228.65m

(* Intersections are reported as down-hole widths, not true widths. The Firm doesn’t but have adequate drilling info to precisely calculate true widths of drill gap intersections)
MAP-073 and MAP-076
MAP-073 and MAP-076 have been drilled on the identical part (Fig 1)
Fig1. Part, Holes MAP-073, 076
Each holes have been drilled to help in resolving a geological interpretation problem within the south of the APTA zone, that had resulted from earlier holes having been drilled towards the east or having stopped in need of the mineralised zones.
Each holes have been profitable in resolving the questions posed, and each returned substantial intersections of high-grade gold and average zinc as reported.
MAP-074 was drilled up dip of a bunch of earlier holes that had outlined a posh zone of gold mineralisation (Fig 2).
Mineralisation in MAP-074 was thinner than anticipated, and decrease gold grade, however like gap MAP-075 confirmed enhanced zinc grades.
Additional work will likely be accomplished, nevertheless drilling additional up dip with gap MAP-078 visually reveals a thinner breccia package deal and may recommend the breccia zone is pinching out on this path. This info is essential for gaining a better understanding the orientation and zonation of the orebody and is important for concentrating on.
To this finish, gap MAP-080 has simply been commenced down-dip.
Fig 2. Part, Gap MAP-074
Gap MAP-075, Excessive Grade Zinc
Gap MAP-075 was drilled some 90m down dip of the beforehand introduced MAP-072.
Fig 3. Part, gap MAP-075
Visually, the mineralisation inside the breccia zone intersected in MAP-075 was just like that intersected in MAP-072, nevertheless assay outcomes would recommend MAP-075 has intersected a unique mineralogical area, transitioning from a site that was gold dominant with secondary zinc, to at least one that’s zinc dominant with secondary gold.
Zinc mineralisation in gap MAP-075 is at occasions large, with grades in extra of 30% over small intervals. Each MAP-072 and MAP-075 additionally include minor copper, roughly correlated with zinc, with grades at occasions as excessive as 0.8% Cu.
Such zonation is anticipated and is an integral attribute of Volcanogenic Huge Sulphide (VMS) deposits. Nonetheless, given the orientation issues of earlier drilling, this was the primary gap to indicate this zonation so unequivocally and so present tangible steering for additional concentrating on.
Gap MAP-077 has been accomplished and was positioned an extra 90m down dip of MAP-075 and has visually demonstrated related intersections of large sulphide and pervasive silicification. All samples from MAP-077 have been submitted for assay and as soon as returned, will present further steering that ought to help in additional creating an understanding of the zonation inside the VMS system.
Mobilisation of 4th rig
The preliminary 2,300m drill program has now been largely accomplished and as deliberate, has addressed quite a lot of excellent geological questions. This has offered precious steering as to the character and distribution of the mineralisation at APTA that may permit future drilling to be extra effectively focused.
A choice has now been taken to maneuver into the subsequent part of drilling with a 7,000m program and to that finish, a 4th diamond drill is to be mobilised to web site in coming days.
Orosur CEO Brad George commented:
“After a lot glorious work and several other phases of drilling, it’s pleasing to be on the level the place we at the moment are creating a better understanding of APTA, its nature and genetic controls. Additionally it is testomony to the advantages of being in a JV with main firms that provides us entry to a depth and breadth of expertise and technical experience that Orosur alone doesn’t possess.
The rising image of APTA as a polymetallic, gold wealthy, VMS deposit is each a chance and a problem – a problem in having to now perceive the zonation that’s inherent in VMS deposits, however a chance in that the polymetallic nature (particularly at excessive grades) is invariably a optimistic for venture economics”
