VANCOUVER, British Columbia, May 23, 2023 (GLOBE NEWSWIRE) -- Mirasol Resources Ltd. (TSX-V: MRZ) (OTC: MRZLF) (the "Company" or "Mirasol") is pleased to report the signing of an Option Agreement ("Agreement") with Cerro Vanguardia SA Gold-Silver Mine ("CVSA") owned by AngloGold Ashanti (92.5%) and FOMICRUZ S.E. (7.5%) for the exploration of Mirasol's Claudia Gold-Silver Project ("Claudia"), located directly south of the CVSA Gold-Silver Mine in the province of Santa Cruz, Argentina.
"The Agreement with CVSA demonstrates the potential for continued discovery and resource development at Claudia," Mirasol's President Tim Heenan stated. "The 2% royalty has the potential to offer significant near-term value to Mirasol shareholders as resources defined at Claudia could be processed quickly and efficiently at the nearby Cerro Vanguardia mill."

The extensive 65,192-hectare Claudia Gold-Silver Project is a highly prospective, low sulphidation epithermal (LSE) gold/silver project, located in the Deseado Massif of Argentina's Santa Cruz province, directly adjacent to the southern border of the producing CVSA Mine. Five distinct prospective vein trends have been identified at Claudia including the Curahue Vein Field and the Rio Seco Prospect. In 2012, Mirasol discovered the large northwest trending 15-kilometer long Curahue vein field, which may be considered a southern parallel structure, similar to the controlling structures further north at the Cerro Vanguardia vein field. Curahue hosts six isolated vein segments. Claudia also hosts two shallow paleo-surface expressions of "sinter fields" at both Calandria and Rio Seco. These sinters are considered attractive targets as any mineralized structure found beneath would be completely preserved and not reduced by erosion. Neither of these sinter occurrences have been drilled to date. The exploration potential of the Claudia Project, particularly along the largely untested Curahue and Rio Seco trends, show clear potential for Vanguardia-style vein-hosted epithermal gold-silver mineralization.

Terms of the Claudia Option Agreement
a) Within the first two years of the Agreement CVSA may complete such mapping and sampling, trenching and geophysics as required in its absolute discretion to develop drill targets, and fulfill a minimum drilling commitment of 2,500 meters diamond drilling; and then CVSA will have the option, subject to the term of the agreement, to:
1) Complete within three years, not less than an aggregate of 6,000 meters of diamond drilling;
2) Complete within four years, not less than an aggregate of 12,500 meters of diamond drilling;
b) Upon completion of the above commitments, CVSA shall have the right to exercise the Option under the Agreement and subject to the terms of the Royalty Agreement, CVSA shall grant Mirasol a 2% Net Smelter Royalty on future production from the Claudia Project.
History at Mirasol's Claudia Property
The Claudia Project was originally staked in 2004 as part of Mirasol's Santa Cruz exploration program. Mirasol, in conjunction with various joint venture (JV) partners, has completed over 19,000 meters of combined reverse circulation (RC) and diamond core (DDH) drilling, more than 4,000-line kilometers of ground magnetometry, 249-line kilometers (43 km2) of gradient array IP geophysics covering six separate blocks, almost 100-line km's electrical IP- Pole-di-Pole geophysical lines, collected over 3,500 rock chip samples, 4,500 rock trench channel samples from 200 trenches, close to 1000 MMI geochemical soil samples and 1,500km2 in detailed geological mapping.
Between 2006 and 2010 two phases of drilling were completed with a JV partner, including 3,794 meters of drilling in 26 holes and 3,168 meters of RC drilling in 25 holes. Drilling results from these campaigns included multiple intercepts with greater than 100 g/t silver, including five intercepts from 118 g/t silver to 217 g/t silver and up to 1.3 g/t gold.
During 2012, Mirasol's inhouse exploration team expanded and defined the impressive 15 km long Curahue vein trend, which is largely concealed by shallow gravel cover (<5m) and is seen to host six large individual vein trends, namely the Europa, IO, Ganymede, Callisto, Themisto and Sinope segments. Large extensions of these trends have been traced under cover by electrical IP (Gradient Array) geophysical campaigns.

At the Rio Seco prospect, located on the easternmost part of Claudia, Mirasol's early prospecting discovered the first outcropping veins at Claudia where select surface samples returned up to 20.1 g/t gold and 1,175 g/t silver from the "J Vein". Saw-cut channel and trench intersections returned 0.7 meters at 13.9 g/t gold and 229 g/t silver and 10.5 meters of 1.9 g/t gold and 22 g/t silver from mineralized zones along the expansive Rio Seco vein field (see news release June 14, 2012).
During Q2 2012, Mirasol drilled a total of 2,599 meters in 25-holes. The best results included individual assays of up to 0.83 meters at 6.59 g/t gold and 139.3 g/t silver (9.12 g/t gold equivalent) and broad intersections of anomalous gold and silver up to 15.3 meters of 0.29 g/t gold and 50.9 g/t silver (1.22 g/t gold equivalent) (see news release March 4, 2013).
During 2016/17, under a previous JV with CVSA, a combined 7,525 meters of RC and DDH drilling was completed at Claudia. The majority of the drilling was focused along a 2.2-kilometer section of the "IO vein", one of the six prospects identified to-date along the 15 km long Curahue trend (see news release December 16, 2016 and February 17, 2017).
A major "milestone" of the CVSA drilling at the "IO" vein was the discovery of a 600 meter long, open-ended mineralized body hosting silver/gold mineralization which starts a few meters below surface and has been drill tested to a vertical depth of 135 meters. This strongly mineralized trend requires follow-up work both downdip and along the strike of the structure. Highlight results included:
High-grade vein: 0.6 m at 11.72 g/t gold and 1,224 g/t silver.
Vein and veinlet composite: 9.3 m at 1.40 g/t gold and 134.6 g/t silver.
From October 2017 through March 2019, Mirasol with a JV partner drilled 2,529 meters in 12 holes at Claudia. Drilling completed to July 2018 focused mostly at the Curahue prospect, with 10 DDH holes totaling 2,270 m completed, to test targets on the Europa, IO, Themisto and Callisto segments, along the extension of the Curahue trend.
Drill results from the Curahue prospect, Europa and IO vein trends include 0.6 m at 0.08 g/t gold and 610.0 g/t silver, 0.55 m at 1.15 g/t gold and 22.9 g/t silver; and 0.9 m at 1.95 g/t gold and 5.7 g/t silver from the Cilene prospect (see news release September 17, 2018).
Following termination of that JV, Mirasol completed additional surface exploration work resulting in the definition of new drill targets that remain to be tested. A total of 249 new rock chip samples were collected from the Curahue trend, with results up to 7.99 g/t gold and 69 g/t silver. In addition, two new IP geophysical surveys, focused on the Curahue and Themisto prospects, were completed extending existing survey coverage at Claudia (see news release May 8, 2019).
Rubi Copper Project in Chile
Mirasol today also announces that the option agreement on the Rubi Copper Porphyry Project in Chile ("Rubi") with Mine Discovery Fund Pty Ltd. ("MDF"), a private Australian company, has been terminated. MDF exceeded its contractual minimum commitment by spending US$890,000 on exploration during the term of the option agreement (see news release dated October 15, 2020). The exploration program included field mapping, surface sampling, geophysics and 1,887 meters of drilling at the Lithocap and Zafiro targets. Having recovered an undivided 100% interest in Rubi, Mirasol is evaluating options to refine remaining drill targets at Rubi and is currently in discussions with potential alternative partners to drill test these targets.

不列顛哥倫比亞省溫哥華,2023 年 5 月 23 日(GLOBE NEWSWIRE)— Mirasol Resources Ltd.(TSX-V: MRZ)(場外交易所: MRZLF) (那個”公司“或”Mirasol“)欣然報告與AngloGold Ashanti(92.5%)和FOMICRUZ S.E.(7.5%)擁有的Cerro Vanguardia SA金銀礦(“CVSA”)簽署了期權協議(“協議”),用於勘探位於聖克魯斯省CVSA金銀礦以南的米拉索爾克勞迪婭金銀項目(“克勞迪婭”),阿根廷。
“與CVSA的協議表明了克勞迪婭繼續發現和資源開發的潛力,” 米拉索爾總裁蒂姆·海南表示。“2%的特許權使用費有可能爲Mirasol股東提供可觀的短期價值 因爲克勞迪婭定義的資源可以在附近的Cerro Vanguardia工廠快速高效地進行處理。”
圖 1:地區區域地圖
佔地65,192公頃的克勞迪婭金銀項目是一個前景廣闊的低硫化超熱(LSE)黃金/白銀項目,位於阿根廷聖克魯斯省的德塞阿多地塊,直接毗鄰生產CVSA礦的南部邊界。克勞迪婭已經確定了五種不同的潛在靜脈趨勢,包括庫拉休靜脈油田和里約塞科展望。2012年,米拉索爾發現了向西北延伸的15千米長的大型庫拉休靜脈場,這可以被視爲南方的平行結構,類似於更北邊的Cerro Vanguardia靜脈場的控制結構。庫拉休有六個孤立的靜脈片段。克勞迪婭還在卡蘭德里亞和里約塞科舉辦了兩場淺層古地表的 “燒結場” 表演。這些燒結礦被認爲是有吸引力的目標,因爲在下面發現的任何礦化結構都會被完全保存,不會因侵蝕而減少。迄今爲止,這兩個燒結礦點都沒有經過鑽探。克勞迪婭項目的勘探潛力,尤其是基本上未經測試的庫拉休和里約塞科的勘探潛力,顯示出Vanguardia式靜脈承載的超熱金銀礦化的明顯潛力。

克勞迪婭期權協議的條款
a) 在協議的前兩年內,CVSA可以完全自行決定完成所需的測繪和採樣、挖溝和地球物理學,以制定鑽探目標,履行最低鑽探2,500米鑽石鑽探的承諾;然後,根據協議條款,CVSA可以選擇:
1) 三年內完成,總共不少於 6,000 米的金剛石鑽探;
2)在四年內完成,總共不少於12,500米的金剛石鑽探;
b) 完成上述承諾後,CVSA有權行使協議下的期權,根據特許權使用費協議的條款,CVSA應就克勞迪婭項目未來的產量向Mirasol授予2%的淨冶煉廠特許權使用費。
米拉索爾克勞迪婭房產的歷史
克勞迪婭項目最初成立於 2004 年,是米拉索爾聖克魯斯探索計劃的一部分。Mirasol 與多家合資企業 (JV) 合作伙伴共同完成了超過 19,000 米的聯合反循環 (RC) 和金剛石芯 (DDH) 鑽探、超過 4,000 線千米的地面磁力測量、覆蓋六個獨立區塊的 249 線千米 (43 km2) 梯度陣列 IP 地球物理線、近 100 線千米的 IP-Pole-di-Pole 地球物理線,收集了 3,500 多個岩屑樣本,來自 200 個海溝的 4,500 個巖溝河道樣本、近 1000 個 MMI 地球化學土壤樣本和 1,500 千米2 在詳細的地質測繪中。
2006 年至 2010 年間,與合資夥伴完成了兩個階段的鑽探,包括在 26 個洞中鑽了 3,794 米,在 25 個洞中鑽了 3,168 米的鋼筋混凝土鑽探。這些活動的鑽探結果包括多次截獲的銀量大於100 g/t,包括從 118 g/t 白銀到 217 g/t 白銀和高達 1.3 g/t 黃金的五次截獲量。
2012年,Mirasol的內部勘探團隊擴大並定義了令人印象深刻的15公里長的庫拉休礦脈走向,該趨勢在很大程度上被淺層礫石覆蓋層(<5m)所掩蓋,並被認爲是六個大型單體礦脈走向,即歐羅巴、IO、木衛二、卡利斯托、Themisto和Sinope段。電子IP(梯度陣列)地球物理活動掩蓋了這些趨勢的大幅延伸。

在位於克勞迪婭最東端的里約塞科勘探區,米拉索爾的早期勘探在克勞迪婭發現了第一條露頭礦脈,精選的地表樣本從 “J Vein” 返回了高達20.1克/噸的黃金和1,175克/噸的銀。鋸切的河道和溝槽交叉口以13.9克/噸的速度返回了0.7米的黃金和229克/噸的銀,從廣闊的里約塞科礦脈礦牀沿線的礦化區返回了10.5米的1.9克/噸金和22克/噸的銀(見2012年6月14日新聞稿)。
在 2012 年第二季度,Mirasol 在 25 個洞中總共鑽了 2,599 米。最佳結果包括在6.59克/噸黃金和139.3克/噸銀(相當於9.12克/噸金)下進行高達0.83米的單獨檢測,以及異常金和銀的廣泛交叉點,最高可達15.3米(0.29克/噸金當量)(見2013年3月4日新聞稿)。
在2016/17年度,根據之前與CVSA的合資企業,在克勞迪婭完成了合計7525米的RC和DDH鑽探。大部分鑽探集中在 “IO 礦脈” 2.2 公里路段上,這是迄今爲止沿着 15 千米長的庫拉休趨勢確定的六個勘探區之一(見2016年12月16日和2017年2月17日的新聞稿)。
一個大滿貫的”里程碑“在CVSA的'IO'礦脈鑽探中,發現了一個長達600米的開放式礦化體,其中含有銀/金礦化,該礦化體從地表以下幾米處開始,已經過鑽探測試,垂直深度爲135米。這種強烈的礦化趨勢需要在結構向下和向上都進行後續工作。亮點結果包括:
高級靜脈: 0.6 m,每噸 11.72 g/t 黃金,1,224 g/t 白銀。
靜脈和靜脈複合物: 9.3 m,每噸 1.40 g/t 黃金,134.6 g/t 白銀。
從 2017 年 10 月到 2019 年 3 月,米拉索爾與合資夥伴在克勞迪婭的 12 個洞中鑽了 2,529 米。截至2018年7月完成的鑽探主要集中在庫拉休勘探,共完成了10個DDH孔,總計2270米,用於測試庫拉休勘探區的目標 歐羅巴, IO, Themisto 和 卡利斯托 細分市場,沿着庫拉休趨勢的延伸。
來自庫拉休勘探、歐羅巴和伊奧礦脈趨勢的鑽探結果包括0.6米的黃金和610.0克/噸的白銀,0.55米的1.15克/噸黃金和22.9克/噸的白銀;以及來自Cilene勘探區的0.95克/噸黃金和5.7克/噸的白銀(見2018年9月17日新聞稿)。
該合資公司終止後,Mirasol完成了額外的地表勘探工作,從而確定了有待測試的新鑽探目標。從庫拉休趨勢中共採集了249個新的岩石碎片樣本,結果高達7.99克/噸的金和69克/噸的銀。此外,兩項以庫拉休和Themisto前景爲重點的新知識產權地球物理調查已經完成,擴大了克勞迪婭的現有調查覆蓋範圍(見2019年5月8日新聞稿)。
智利的魯比銅項目
Mirasol今天還宣佈,與澳大利亞私營公司Mine Discovery Fund Pty Ltd.(“MDF”)達成的智利Rubi Copper Porphyry項目(“Rubi”)的期權協議已終止。在期權協議期限內,MDF在勘探上花費了89萬美元,超過了合同的最低承諾(見2020年10月15日的新聞稿)。勘探計劃包括實地測繪、地表採樣、地球物理學以及在Lithocap和Zafiro目標上進行1,887米的鑽探。在收回了Rubi的100%不可分割權益後,Mirasol正在評估完善Rubi剩餘鑽探目標的備選方案,目前正在與潛在的替代合作伙伴討論對這些目標進行鑽探測試。
