VANCOUVER, British Columbia, April 03, 2023 (GLOBE NEWSWIRE) -- Norsemont Mining Inc. (CSE: NOM, OTCQB: NRRSF, FWB: LXZ1) ("Norsemont" or the "Company") announces results of the final two drill holes from its Maiden diamond drilling program at the Choquelimpie high sulphidation epithermal gold-silver-copper project in northern Chile.
These last holes further extend the mineralisation within the hydrothermal alteration footprint covering 27 square kilometres and are located near Drill Hole MV21-009, which returned a significant 170 metre intercept grading 1.84 g/t Au Equivalent, including 95 metres of 1.92 g/t Au Equivalent. (See March 31, 2022, news release).
Mineralisation remains open for extension peripheral to the Choque pit and to depth.
The expanded envelope of mineralisation and the increase in gold grade at depth in hole MV21-009 as well as the presence of epithermal copper mineralisation support the interpretation of potential porphyry Au-Cu mineralisation beneath this hole and extending more than 500 metres to the northeast below hole MV21-005.
Highlights of the final two holes include:
Hole MV21-010 yielded 61.0 metres grading 0.47 grams per tonne ("g/t") gold ("Au") between 239 - 300 metres depth. This mineralised interval expands the known footprint of mineralisation in the Choque Pit area, both along strike and to depth.
Hole MV21-008: yielded 10.0 metres grading 1.61 g/t Au and 2.8 g/t Ag from 122 – 132 metres depth. This intercept is interpreted as being associated with peripheral veinlets forming a halo around high-grade mineralisation and may be indicative of similar grade mineralisation at depth.
The Maiden Diamond Drilling Program Summary:
Norsemont completed ten diamond drill holes for 3,144.1 metres during the Q4 2021 drill campaign (See Figure 1). A detailed map of holes in the area of the Vizcacha and Choque Pits and a table of significant gold intercepts are shown below in Figure 2, together with cross sections in Figures 3 and 4.

Drill hole MV21-008 tested the eastward extension of the Choque mineralisation. The hole cut Au-polymetallic peripheral veinlets typically related to the halo zone peripheral to high-grade mineralisation. Hydrothermal alteration is observed as quartz-kaolinite-illite, with local silicified structures containing pyrite-(±sphalerite-galena & enargite) mineralisation. Gold and silver are anomalous throughout the hole, with the most significant intercept being:
10 metres @ 1.61 g/t Au & 2.8 g/t Ag from 122 – 132 metres depth
MV21-010 tested the SW extension of the Choque mineralisation. This hole confirms the depth extension of the hydrothermal breccia, that remains open to the NE, E, SE and to depth. A hydrothermal alteration assemblage of quartz-illite-pyrophyllite was observed, which is typical of the transition from an epithermal to a porphyry environment. The sulphide mineralisation observed at depth consists of 6-10% pyrite with traces of sphalerite, galena and enargite.
61 metres @ 0.47 g/t Au & 0.78 g/t Ag from 239 – 300 metres depth, including 15 metres grading 0.71 g/t Au & 1.43 g/t Ag from 271 – 286 metres depth

Figure 4: Cross-section B-B' through drill hole MV21-010 showing gold intercepts and a preliminary geological interpretation. Mineralisation is open along strike and to depth. Significant Au grades in the last 61 metres of drill hole MV21-010 confirm the extension to depth and continuity of the mineralised hydrothermal breccia.
John Currie, Norsemont's VP of Exploration states: "Our initial diamond drilling program at Choquelimpie was highly successful as it has extended the high-grade epithermal gold and silver mineralisation laterally and vertically beyond the historical drilling, The drill campaign also identified areas where the mineralised envelope can be expanded. In addition, we confirmed the presence of a mineralised porphyry system below the epithermal zone.
We now have a range of exciting targets for follow-up drilling programs. We look forward to the next phase of exploration, which will be focussed on extending mineralisation outwards and to depth relative to these 2021 drill holes. In addition, we plan to test the hypothesis of a Au-Cu-Mo mineralised porphyritic intrusive at depth beneath the Choque and Viscacha pits."
Marc Levy, Norsemont's CEO comments: "The results continue to expand the known footprint of mineralization at Choquelimpie and highlight new areas for drill testing and resource expansion. We are excited to resume work on the property during the upcoming 2023 exploration season."
QA/QC Parameters
Drill core for the Choquelimpie 2021 drill program is collected directly from the drill site by company staff and taken to the core shack at the Choquelimpie camp. Drill core is logged, photographed, and sampled by staff who insert certified reference materials into the sampling sequence when/where appropriate. Sample lengths are marked at 1.0 metre intervals and the core is cut by a diamond blade rock saw, with half of the cut core placed in individual bar-code numbered polyurethane bags and half placed back in the original core box for permanent storage. The sample bags are sealed, placed in security-sealed sacks, and then delivered by company staff to the Andes Analytical Laboratory (AAA) sample receiving facilities in Arica, Chile.
All drill core samples reported in this news release were analysed at AAA in Santiago, Chile utilizing their ICP_AES_HF38m1 analytical package. This comprises a four-acid digestion followed by a 38-element ICP-MS scan, in conjunction with the AEF_AAS_1E42 40g Fire Assay with AAS finish for gold on all samples. Samples that return values >10 ppm gold from fire assay and AAS are determined by using fire assay and a gravimetric finish (lab code AEF_GRV_1E43). Samples that return values >5,000 ppm for copper and >400 ppm silver by ICP analysis are determined by four acid digestion AAS finish assay (lab codes 4A-HF_AAS_1E13_ppm and 4A-HF_AAS_1E08_0.25-100 respectively).
The information presented in this news release was collected and prepared by SCM Vilacollo staff in accordance with Canadian regulatory requirements as set out in National Instrument 43-101. QA/QC for the analytical results was reviewed by Mr. Enrique Grez, an independent qualified person, registration number 0015 of the Comisión Calificadora de Recursos y Reservas Mineras de Chile, and a Qualified Person as defined in National Instrument 43-101, Standards for Disclosure for Mineral Projects.
Mr. Art Freeze, P.Geo, Director of Norsemont Mining as well as a qualified person as defined by National Instrument 43-101, has supervised the preparation of the technical information in this news release.

溫哥華,不列顛哥倫比亞省,2023年4月3日(環球網)--諾斯蒙特礦業公司(CSE:NOM,OTCQB:NRRSF,FWB:LXZ1)(“諾斯蒙特“或”公司“)宣佈了其在智利北部Choquelimpie高硫化淺成金銀銅礦專案的Maiden鑽石鑽探專案的最後兩個鑽孔的結果。
這些最後的孔洞進一步延伸了熱液蝕變足跡內的礦化,佔地27平方公里,位於MV21-009鑽孔,該鑽孔返回了顯著的170米截距分級1.84克/噸金當量,其中包括95米1.92克/噸金當量。(見2022年3月31日新聞稿)。
礦化仍然開放,可以延伸到Choque礦坑的外圍和深度。
MV21-009孔中礦化包絡的擴大和深部金品位的增加以及淺成熱液銅礦化的存在支持解釋該孔下潛在的斑岩金-銅礦化,並在MV21-005孔下向東北方向延伸500多米。
最後兩個洞的亮點包括:
MV21-010孔屈服61.0米分級0.47克/噸(“g/t”)黃金(“Au”),深度239-300米。這一礦化間隔擴大了Choque礦坑地區已知的礦化足跡,包括走向和深度。
MV21-008孔:已屈服在122-132米深度,10.0米品位1.61克/噸金和2.8克/噸銀。這種截取被解釋為與外圍細脈有關,在高品位礦化周圍形成光環,並可能指示深部類似品位的礦化。
少女鑽石鑽探計劃摘要:
諾斯蒙特公司在2021年第四季度的鑽探活動中完成了10個鑽石鑽孔,共3,144.1米(見圖1)。下面的圖2以及圖3和圖4中顯示了vizcacha坑和Choque坑區域的詳細孔圖和重要的黃金截獲物的表格。

鑽孔MV21-008測試了喬克礦化向東的延伸。孔洞切割的金多金屬外圍細脈通常與光暈帶外圍至高品位礦化有關。熱液蝕變以石英-高嶺石-伊利石為主,局部矽化構造含黃鐵礦-(±閃鋅礦-方鉛礦-輝石)礦化。黃金和白銀在整個洞中都是異常的,最重要的截距是:
從122-132米深10米@1.61克/噸Au和2.8 g/t Ag
MV21-010測試了喬克礦化的西南延伸。這個洞證實了熱液角礫巖的深度延伸,它仍然對NE、E、SE和深度開放。觀察到石英-伊利石-葉蠟石的熱液蝕變組合,這是淺成熱液環境向斑岩環境轉變的典型特徵。在深部觀察到的硫化物礦化由6-10%的黃鐵礦組成,並有微量的閃鋅礦、方鉛礦和輝鋅礦。
從239-300米深度61米@0.47克/噸金和0.78克/噸銀,包括從271-286米深度15米分級0.71克/噸金和1.43克/噸銀

圖4:橫截面B-B‘貫通鑽孔MV21-010,顯示了金礦截獲和初步地質解釋。礦化沿走向和深度是開放的。MV21-010鑽孔最後61米的顯著金品位證實了礦化熱液角礫巖的延伸深度和連續性。
NorSemont勘探副總裁John Currie表示:“我們在Choquelimpie的最初鑽石鑽探計劃非常成功,因為它將高品位淺成熱液金銀礦化橫向和垂直擴展到歷史鑽探之外,鑽探活動還確定了礦化包層可以擴大的區域。此外,我們證實了淺成熱液帶下方存在礦化斑岩系統。
我們現在有了一系列令人興奮的後續鑽探計劃目標。我們期待著下一階段的勘探,重點將是向外延伸礦化以及相對於這2021個鑽孔的深度。此外,我們計劃測試喬克坑和維斯卡沙坑下方深處Au-Cu-Mo礦化斑岩侵入岩的假說。
諾斯蒙特公司首席執行官梅克·利維表示:“這一結果繼續擴大了Choquelimpie已知的礦化足跡,並突出了鑽探測試和資源擴展的新領域。我們很高興能在即將到來的2023年勘探季節恢復該礦產的工作。”
