NOM:CC - Choquelimpie Sampling Extends Surface Gold-Silver Oxide Mineralized Zones
(TheNewswire)
Vancouver, BC - TheNewswire - April 12, 2023 - Norsemont Mining Inc. (CSE:NOM ) ( OTC:NRRSF ) ( FWB:LXZ1) ( “ Norsemont ” or the “ Company ” ) announces results of its inaugural surface outcrop geochemical samplingcampaign.
Highlights:
-
Surface outcrop sampling resultsreturned long intervals of significant oxide Au-Ag values, outside ofand peripheral to the historical mined pits, thus extending thepotential for additional near-surface heap-leachable resources.Additional mapping and sampling are planned to further define theextension of this potentially significant source ofmineralisation.
-
Strong geochemical anomalies for Cu,Mo and Au from the Vizcacha Porphyry sector enhance our interpretationthat this newly mapped area represents the upper portions of atelescoped porphyry system. Additional mapping, geochemical samplingand geophysics will be utilized to define drill targets atViscacha.
Surface Outcrop Chip Channel Sampling
The initial outcrop chip and channel sampling campaignwas carried out during the months of November 2021 and March 2022 withthe objectives of:
-
Testing the extensive areas of potentially mineralisedleached rock, observed in road cuts and mine benches, that wereoverlooked by previous operators.
-
Confirming and expanding the oxide gold footprint ofthe Choque-Intermedio pit areas, as evidenced in drill hole MV21-009(15 metres @ 0.84 grams per tonne Au from surface – news releaseMarch 31, 2022).
-
Evaluating the new porphyry veinlet zone near theVizcacha Pit.
In total, 517 outcrop samples were collected in 2 metrelong by 10 cm wide channel samples, each weighing between 3 to 5kilograms. Channel samples collected in the Silica Ledge sector were 1metre long by 10 centimetres wide. Where possible, for example, alongthe banks of roadcuts, sampling was continuous.
The results show:
• Continuous and robust Au-Ag oxide mineralisationon the eastern margin of the Choque and Intermedio pit areas.Comprehensive follow-up sampling will be conducted to define the fullextent of this potential near-surface mineralization. The mostsignificant results were: 60 metres @ 0.97 grams per tonne Au and 21grams per tonne Ag, including 2 metres @ 10.93 grams per tonne Au and46 grams per tonne Ag.
These results confirm the presence of more widespreadnear-surface Au-Ag oxide mineralisation in the Choque-Intermedio pitareas. Norsemont is currently conducting metallurgical testwork inthis area, with the hope that positive results will add significanttonnages to the leachable resource.
It should be noted that such grades of near-surfaceoxide mineralisation are typical of many large-tonnage open-pitheap-leach mines, in contrast to the small-tonnage high-grade mineoperated by the previous operators of Choquelimpie.
• The Vizcacha Porphyry Zone returned channelsample results ranging from 0.1 - 0.4 grams per tonne Au associatedwith characteristic porphyry-related A-veins and black banded quartzveins, occurring as sheeted swarms and stockworks. In addition, amolybdenum anomaly related to B-veins is present (e.g. 8m @ 41 ppmMo). This veinlet-hosted mineralization occurs in a daci-andesiteporphyry, with phyllic alteration overprinted by quartz-pyrophyllitealteration and cut by structurally controlled corridors of highsulphidation mineralisation (e.g. 1 metre @ 2.14 grams per tonne Auand 361 grams per tonne Ag as well as 1 metre @ 1.48 grams per tonneAu and 170 grams per tonne Ag).
These assay results and geological interpretations, combined with thegeology observed in our recent drilling of the historical pits, leadour technical team to conclude that we are situated in the mid tolower portion of a high-sulphidation epithermal system, overlying a potentially large Au-Cu-Mo porphyryintrusive target at depth.

John Currie, Norsemont’s VP of Exploration states:“Our initial surface sampling program at Choquelimpie was highlysuccessful, as the results from this campaign have outlinedpotentially heap-leachable near-surface oxide Au-Ag mineralisation, inboth the epithermal and high-level porphyry environments. We nowhave a range of exciting targets that merit aggressive follow-upexploration. The near-surface oxide potential is especially exciting.With the first phase of surface chip and channel sampling now plotted,we are confident that we will be able to define a substantial volumeof oxide Au-Ag mineralised rock amenable to heap leaching, to add toour already existing low-grade stockpiles. Extensive outcrop,road-cut and soil talus geochemical sampling will be one of ourpriorities when we resume the field work.”
Marc Levy, Norsemont’s CEO comments, “Theseencouraging surface sampling results continue to expand the size ofthe mineralized gold-silver oxide footprint at Choquelimpie andhighlight new areas for drill testing and resource expansion. One ofour tasks will also be to chase the mineralisation interceptedin drill hole MV21-009 that returned 170.0 mgrading 1.35 g/t Au and 18.3 g/t Ag (See News Release dated March 31,2022). Finally, we are particularly excited to also test thepotentially large copper-gold-molybdenum porphyry intrusive target atdepth. Success in these areas would change the future ofChoquelimpie.”
Sampling Methodology,Chain of Custody, Quality Control and Quality Assurance:
Surface outcrop chip and channel samples of 1.0 - 2.0 metres lengthwere collected, bagged and tagged by company staff. In a secureprocessing facility, Company staff inserted a series of blind blanks,certified reference materials and sample duplicates in the samplestream, as part of the Company’s QA/QC protocol. Sample bags weresealed, placed in security-sealed sacks, and then delivered by Companystaff to the Andes Analytical Laboratory sample receiving facility inArica, Chile.
All outcrop chip-channel samples reported in this news release wereanalysed at AAA in Santiago, Chile utilising their ICP_AES_HF38m1analytical package. This comprises a four-acid digestion followed by a38-element ICP-MS scan, in conjunction with the AEF_AAS_1E42 40g FireAssay with AAS finish for gold on all samples. Samples that returnvalues >10 ppm gold from fire assay and AAS are determined by usingfire assay and a gravimetric finish (lab code AEF_GRV_1E43). Samplesthat return values >5,000 ppm for copper and >400 ppm silver byICP analysis are determined by four acid digestion AAS finish assay(lab codes 4A-HF_AAS_1E13_ppm and 4A-HF_AAS_1E08_0.25-100respectively).
