Aftermath Provides Berenguela Project Update
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.
溫哥華,不列顛哥倫比亞省-(Newsfile Corp.-2023年3月28日)-After Silver Ltd.(多倫多證券交易所股票代碼:AAG)(場外交易市場代碼:AAGFF)(以下簡稱“公司”)很高興為您提供祕魯南部Berenguela銀銅錳礦專案的最新情況。
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,該公司公佈了該礦產的最新和擴大的礦產資源(見2023年3月1日的AAG新聞稿)。2021年至2022年的鑽探在一定程度上是為了從貝倫蓋拉的各種地質和冶金領域獲得大量(Pq直徑)岩心樣品。美國內華達州雷諾市的Kappes Cassidy正在設計一項針對選定復合岩心樣品的綜合臺架試驗選礦計劃,重點是優化銀、錳、銅和鋅的加工和回收,以及潛在的錳產品,包括農業和電池級硫酸錳(MnSO)。4)。該公司目前預計該計劃將於2023年第三季度/第四季度完成。這一結果將為預計於2023年底開始的AFTER計劃初步經濟分析提供關鍵的技術投入。
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.
代表主要礦化區的復合岩心樣品目前正在該公司位於阿雷基帕的岩心儲存設施進行組裝。它們將被運往KCA在雷諾的設施,以促進處理前選礦測試,其中將包括礦石分選。作為第一步,正在對來自當前和歷史鑽探的岩心樣品進行初步目測評估,重點是各種礦物的分佈及其與化驗等級的關係。
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.
野外工作預計將於六月重新開始,勘探和測繪已知礦化以東的露頭、歷史鑽探和現有地下工作所顯示的潛在延伸。這項工作還將調查主要貝倫蓋拉礦化以東的一個潛在侵入中心。

Geology
地質學
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的礦化主要賦存於中白堊世的厚層褶皺灰巖和白雲石化灰巖中。發生了幾個大型黑色塊狀、片狀和受斷裂控制的錳氧化物交代礦化,並伴隨著銀、銅和鋅的富集。礦化在地層學上位於區域拆離帶上方,特別是在底部地壘與碳酸鹽主巖更強烈的褶皺重合的地方。
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.
礦化的大部分通常以被侵蝕的同形殘留物的形式保存,通常暴露在地表,傾向於105-120度。測繪和資源類比顯示,礦化沿走向延伸約1,300米(包括100米的不連續面),寬度為200至400米。鑽探顯示,礦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被解釋為位於區域拆離帶上方的低溫氧化環境下的碳酸鹽置換礦床(CRD),具有不尋常的次生氧化錳型風格。

Cautionary Note to US Investors - Mineral Resources
給美國投資者的警示-礦產資源
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.
本新聞稿是根據加拿大國家文書43-101-礦物專案披露標準(‘NI 43-101’)和加拿大采礦、冶金和石油定義標準的要求編寫的,這兩項標準與美國證券法的要求不同。NI 43-101是加拿大證券管理人制定的一項規則,為發行人對有關礦產專案的科學和技術資訊進行的所有公開披露建立了標準。加拿大的公開披露標準,包括NI 43-101,與美國證券交易委員會(“美國證券交易委員會”)的要求有很大不同,本文中包含或提及的有關礦化、礦床、礦產儲備和資源資訊的資訊可能無法與美國公司披露的類似資訊進行比較。
