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.

温哥华,不列颠哥伦比亚省,2023年4月3日(环球网)--诺斯蒙特矿业公司(CSE:NOM,OTCQB:NRRSF,FWB:LXZ1)(“诺斯蒙特“或”公司“)宣布了其在智利北部Choquelimpie高硫化浅成金银铜矿项目的Maiden钻石钻探项目的最后两个钻孔的结果。
这些最后的孔洞进一步延伸了热液蚀变足迹内的矿化,占地27平方公里,位于MV21-009钻孔,该钻孔返回了显著的170米截距分级1.84克/吨金当量,其中包括95米1.92克/吨金当量。(见2022年3月31日新闻稿)。
矿化仍然开放,可以延伸到Choque矿坑的外围和深度。
MV21-009孔中矿化包络的扩大和深部金品位的增加以及浅成热液铜矿化的存在支持解释该孔下潜在的斑岩金-铜矿化,并在MV21-005孔下向东北方向延伸500多米。
最后两个洞的亮点包括:
MV21-010孔屈服61.0米分级0.47克/吨(“g/t”)黄金(“Au”),深度239-300米。这一矿化间隔扩大了Choque矿坑地区已知的矿化足迹,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/吨金和2.8克/吨银。这种截取被解释为与外围细脉有关,在高品位矿化周围形成光环,并可能指示深部类似品位的矿化。
少女钻石钻探计划摘要:
诺斯蒙特公司在2021年第四季度的钻探活动中完成了10个钻石钻孔,共3,144.1米(见图1)。下面的图2以及图3和图4中显示了vizcacha坑和Choque坑区域的详细孔图和重要的黄金截获物的表格。

图2:乔克坑平面图,显示MV21-008和010号钻孔中的黄金截留物。MV21-006和009洞的结果此前分别于2022年3月2日和3月31日公布。
钻孔MV21-008测试了乔克矿化向东的延伸。孔洞切割的金多金属外围细脉通常与光晕带外围至高品位矿化有关。热液蚀变以石英-高岭石-伊利石为主,局部硅化构造含黄铁矿-(±闪锌矿-方铅矿-辉石)矿化。黄金和白银在整个洞中都是异常的,最重要的截距是:
从122-132米深10米@1.61克/吨Au和2.8 g/t Ag
MV21-010测试了乔克矿化的西南延伸。这个洞证实了热液角砾岩的深度延伸,它仍然对NE、E、SE和深度开放。观察到石英-伊利石-叶蜡石的热液蚀变组合,这是浅成热液环境向斑岩环境转变的典型特征。在深部观察到的硫化物矿化由6-10%的黄铁矿组成,并有微量的闪锌矿、方铅矿和辉锌矿。
从239-300米深度61米@0.47克/吨金和0.78克/吨银,包括从271-286米深度15米分级0.71克/吨金和1.43克/吨银
图3:横截面A-A‘贯通钻孔MV21-008,显示了重要的金矿截获和初步地质解释。矿化沿走向和深度是开放的。
图4:横截面B-B‘贯通钻孔MV21-010,显示了金矿截获和初步地质解释。矿化沿走向和深度是开放的。MV21-010钻孔最后61米的显著金品位证实了矿化热液角砾岩的延伸深度和连续性。
NorSemont勘探副总裁John Currie表示:“我们在Choquelimpie的最初钻石钻探计划非常成功,因为它将高品位浅成热液金银矿化横向和垂直扩展到历史钻探之外,钻探活动还确定了矿化包层可以扩大的区域。此外,我们证实了浅成热液带下方存在矿化斑岩系统。
我们现在有了一系列令人兴奋的后续钻探计划目标。我们期待着下一阶段的勘探,重点将是向外延伸矿化以及相对于这2021个钻孔的深度。此外,我们计划测试乔克坑和维斯卡沙坑下方深处Au-Cu-Mo矿化斑岩侵入岩的假说。
诺斯蒙特公司首席执行官马克·利维表示:“这一结果继续扩大了Choquelimpie已知的矿化足迹,并突出了钻探测试和资源扩展的新领域。我们很高兴能在即将到来的2023年勘探季节恢复该矿产的工作。”
