Vancouver, British Columbia--(Newsfile Corp. - March 28, 2023) - Aftermath Silver Ltd. (TSXV: AAG) (OTCQX: AAGFF) (the "Company" or "Aftermath Silver") is pleased to provide an update on the Berenguela silver-copper-manganese project in southern Peru.

温哥华,不列颠哥伦比亚省-(Newsfile Corp.-2023年3月28日)-After Silver Ltd.(多伦多证券交易所股票代码:AAG)(场外交易市场代码:AAGFF)(以下简称“公司”)很高兴为您提供秘鲁南部Berenguela银铜锰矿项目的最新情况。

On March 2nd, 2023 the Company published an updated and expanded mineral resource for the property (see AAG News release dated March 1, 2023). Drilling in 2021-2 was in part designed to obtain bulk (PQ diameter) core samples from various geological and metallurgical domains at Berenguela. A comprehensive bench-test beneficiation program on selected composite core samples is being designed by Kappes Cassidy of Reno, Nevada, USA, focusing on optimising processing and recoveries of silver, manganese, copper, and zinc, and on potential manganese products including agricultural and battery grade manganese sulphate (MnSO4). The Company currently anticipates completion of the program in Q3/Q4 of 2023. The results will provide key technical inputs for Aftermath's planned Preliminary Economic Analysis which is expected to begin in late 2023.

2023年3月2日,该公司公布了该矿产的最新和扩大的矿产资源(见2023年3月1日的AAG新闻稿)。2021年至2022年的钻探在一定程度上是为了从贝伦盖拉的各种地质和冶金领域获得大量(Pq直径)岩心样品。美国内华达州雷诺市的Kappes Cassidy正在设计一项针对选定复合岩心样品的综合台架试验选矿计划,重点是优化银、锰、铜和锌的加工和回收,以及潜在的锰产品,包括农业和电池级硫酸锰(MnSO)。4.)。该公司目前预计该计划将于2023年第三季度/第四季度完成。这一结果将为预计于2023年底开始的AFTER计划初步经济分析提供关键的技术投入。

Composite core samples, representing the key mineralized domains, are now being assembled at the Company's core storage facility in Arequipa. They will be shipped to KCA's facility in Reno to facilitate pre-treatment beneficiation testing which will include ore-sorting. As a first step, initial visual evaluations are being carried out on core samples from current and historic drilling focusing on the distribution of various minerals and their relationship with assay grades.

代表主要矿化区的复合岩心样品目前正在该公司位于阿雷基帕的岩心储存设施进行组装。它们将被运往KCA在雷诺的设施,以促进处理前选矿测试,其中将包括矿石分选。作为第一步,正在对来自当前和历史钻探的岩心样品进行初步目测评估,重点是各种矿物的分布及其与化验等级的关系。

Fieldwork is expected to recommence in June with exploration and mapping east of the known mineralisation on potential extensions indicated by outcrops, historic drilling and existing underground workings. The work will also investigate a potential intrusive centre to the east of the main Berenguela mineralization.

野外工作预计将于六月重新开始,勘探和测绘已知矿化以东的露头、历史钻探和现有地下工作所显示的潜在延伸。这项工作还将调查主要贝伦盖拉矿化以东的一个潜在侵入中心。

Geology

地质学

Mineralization at Berenguela is hosted principally in thickly bedded, folded limestones and dolomitized limestones of mid-Cretaceous age. Several large bodies of black massive, patchy, and fracture-controlled manganese oxide replacement mineralization occur, with associated silver, copper, and zinc enrichment. Mineralisation is stratigraphically localised above a regional detachment zone particularly where footwall horsts coincide with more intense folding of the carbonate hosts.

Berenguela的矿化主要赋存于中白垩世的厚层褶皱灰岩和白云石化灰岩中。发生了几个大型黑色块状、片状和受断裂控制的锰氧化物交代矿化,并伴随着银、铜和锌的富集。矿化在地层学上位于区域拆离带上方,特别是在底部地垒与碳酸盐主岩更强烈的褶皱重合的地方。

The bulk of the mineralisation is typically preserved as eroded synform remnants, usually exposed at surface and trending 105-120 degrees. Mapping and resource modelling shows the mineralisation to extend for roughly 1,300 m along strike (including a 100 m discontinuity) with a width of 200 to 400 m. Drilling has shown the mineralisation to extend to up to 80 m below surface where preserved.

矿化的大部分通常以被侵蚀的同形残留物的形式保存,通常暴露在地表,倾向于105-120度。测绘和资源模拟显示,矿化沿走向延伸约1,300米(包括100米的不连续面),宽度为200至400米。钻探显示,矿化延伸至保存完好的地表以下80米。

Berenguela is interpreted as a carbonate replacement deposit (CRD) of an unusual hypogene Mn-oxide style localised above a regional detachment zone in a low temperature, oxidising setting.

Berenguela被解释为位于区域拆离带上方的低温氧化环境下的碳酸盐置换矿床(CRD),具有不寻常的次生氧化锰型风格。

Cautionary Note to US Investors - Mineral Resources

给美国投资者的警示-矿产资源

This News Release has been prepared in accordance with the requirements of Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (''NI 43-101'') and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards, which differ from the requirements of U.S. securities laws. NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian public disclosure standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the "SEC"), and information concerning mineralization, deposits, mineral reserve and resource information contained or referred to herein may not be comparable to similar information disclosed by U.S. companies.

本新闻稿是根据加拿大国家文书43-101-矿物项目披露标准(‘NI 43-101’)和加拿大采矿、冶金和石油定义标准的要求编写的,这两项标准与美国证券法的要求不同。NI 43-101是加拿大证券管理人制定的一项规则,为发行人对有关矿产项目的科学和技术信息进行的所有公开披露建立了标准。加拿大的公开披露标准,包括NI 43-101,与美国证券交易委员会(“美国证券交易委员会”)的要求有很大不同,本文中包含或提及的有关矿化、矿床、矿产储备和资源信息的信息可能无法与美国公司披露的类似信息进行比较。
