VANCOUVER, BC / ACCESSWIRE / October 7, 2021 / Tinka Resources Limited ("Tinka" or the "Company") (TSXV:TK)(BVL:TK)(OTCQB:TKRFF) is pleased to announce initial high grade copper-gold surface sampling results from the Silvia NW target, one of several prospective areas within the Company's 100%-owned Silvia Project which was recently acquired (see news release dated July 12, 2021). Silvia NW is located in the Huanuco region of central Peru, 30 km from the Company's flagship Ayawilca project and 90 km along strike south of the Antamina copper mine (see Figure 1).

不列颠哥伦比亚省温哥华/ACCESSWIRE/2021年10月7日/廷卡资源有限公司 ("丁卡“或”公司") (TSXV:TK)(BVL:TK)(OTCQB:TKRFF)我很高兴地宣布Silvia NW目标的初步高品位铜-金表面采样结果,该目标是公司最近收购的全资拥有的Silvia项目的几个远景地区之一(见2021年7月12日的新闻稿)。Silvia NW位于秘鲁中部的Huanuco地区,距离公司的旗舰Ayawilca项目30公里,沿Antamina铜矿以南的Strike 90公里(见图1)。

Silvia NW is prospective for copper-gold skarn mineralization along a 3 km x 1 km trend that has seen minimal exploration and no drilling. Tinka's detailed sampling at "Area A", one of three mineralized zones at Silvia NW (see Figure 2), has discovered high-grade copper-gold mineralization associated with apparently continuous outcrops of skarn covering an area of approximately 400 metres by 100 metres, open in all directions. Widespread scree intermittently covers the outcrops and has limited the lateral extent of this early sampling (see Figures 3, 4 & 5).

Silvia NW沿3千米×1千米的方向寻找铜金矽卡岩型矿化,勘探量极小,没有钻探。廷卡在“A区”--西北部Silvia的三个矿化区之一(见图2)--进行的详细取样发现,高品位铜金矿化与明显连续露头的矽卡岩有关,面积约为400米乘100米,四面八方都是开阔的。大面积的碎屑间歇性地覆盖露头,限制了早期取样的横向范围(见图3、4和5)。

Highlights of sampling from Area A at Silvia NW:

西尔维亚西北部A区采样亮点:

  • A total of 108 trench and rock chip samples were collected over a 400 m x 100 m area of semi-continuous skarn:
    • Average grade of all samples is 0.79% copper & 0.60 g/t gold (1.24% CuEQ*);
    • Copper ranges between 0.01% to 12.31% Cu, and gold ranges between 0.01 g/t to 18.60 g/t Au;
  • There is a strong positive correlation between copper and gold;
  • Copper occurs as chalcopyrite with chalcocite and covellite (and minor copper oxides) in green garnet-magnetite skarn associated with quartz feldspar porphyry (QFP) dikes - mineralization occurs in both limestone ("exoskarn") and QFP ("endoskarn");
  • Skarn mineralization is open in all directions under shallow scree cover;
  • Rock samples are representative, non-selective, trench or continuous rock chip samples (1-2m wide) covering various rock types including skarn, QFP and limestone;
  • Exploration is continuing at Area A, B and C along the 3 km northeast-southwest trend.
  • 在400米x 100米的半连续矽卡岩区采集了108个海沟和岩屑样本:
    • 所有样品的平均品位为0.79%铜和0.60g/t金(1.24%CuEQ*);
    • 铜的含量范围为0.01%~12.31%,金的含量范围为0.01~18.60g/t Au;
  • 铜与金之间存在较强的正相关关系;
  • 与石英长斑岩(QFP)脉岩共生的绿色石榴石-磁铁矿夕卡岩(QFP)中铜以黄铜矿、辉铜矿和斜铜矿(以及少量铜氧化物)的形式赋存,石灰岩(“外岩浆”)和QFP(“内岩浆”)中均有矿化;
  • 矽卡岩型矿化在浅层筛板覆盖下四通八达;
  • 岩样是代表性的、非选择性的、沟槽状或连续的岩屑样品(宽1~2m),覆盖夕卡岩、QFP和石灰岩等多种岩石类型;
  • 沿着3公里的东北-西南走向,A、B和C区的勘探仍在继续。

Dr. Graham Carman, Tinka's President and CEO, stated: "We are very excited to announce the discovery of high grade copper-gold mineralization in our initial sampling at Silvia NW, located in an underexplored Andean region of central Peru close to our flagship Ayawilca project. We believe that these initial sampling results, covering a surface area of approximately 400 m x 100 m, show the outstanding potential for a large and high-grade skarn deposit that has previously not been recognized. The high levels of gold associated with the copper mineralization is a big positive, as gold significantly increases the potential value of the mineralization. The skarn remains open in all directions."

廷卡公司总裁兼首席执行官格雷厄姆·卡曼博士表示:我们非常高兴地宣布,我们在Silvia NW的初步取样中发现了高品位铜金矿化。Silvia NW位于秘鲁中部未被勘探的安第斯地区,靠近我们的旗舰项目Ayawilca项目。我们相信,这些初步取样结果,占地约400米x 100米,显示出以前没有被发现的大型高品位矽卡岩型矿床的巨大潜力。与铜矿化相关的高水平金是一个巨大的积极因素,因为金显著增加了矿化的潜在价值。

"We believe that we could be seeing the early indications of a high potential, high quality copper-gold prospect at Silvia NW. Exploration is continuing at target Areas B and C with mapping and detailed sampling along the 3 km trend, where additional skarn bodies have been reported in both areas."

“我们认为,我们可能在Silvia NW看到了高潜力、高质量铜金矿远景的初步迹象。B和C目标区的勘探仍在继续,沿着3公里的趋势绘制了地图并进行了详细采样,据报道,这两个地区都发现了更多的矽卡岩体。”

"In addition to our current exploration activities, Tinka continues to advance its outstanding Ayawilca zinc-silver project which we believe is one of the best undeveloped zinc projects in the Americas. A Mineral Resource estimation update was recently released (see news release dated September 27, 2021). A Preliminary Economic Assessment (PEA) for the Ayawilca deposit will be disclosed within weeks."

“除了我们目前的勘探活动外,Tinka还在继续推进其尚未完成的Ayawilca锌银项目,我们认为该项目是美洲最好的未开发锌项目之一。最近发布了矿产资源评估的最新情况(见日期为2021年9月27日的新闻稿)。阿亚维尔卡矿藏的初步经济评估(PEA)将在几周内公布。“

Geology and Sampling Results at Area A

A区地质和取样结果

Tinka's exploration activities at Silvia NW have concentrated to date on detailed mapping and sampling of skarns at Area A, located at the southwestern end of the target area (Figure 2). The skarns are hosted by the Cretaceous Jumasha Formation, a thick (> 2km) sequence of limestones that form a major part of the fold and thrust belt in central Peru and host to several major skarn deposits in Peru (including Antamina). The limestone at Area A has been intruded by quartz feldspar porphyry dikes and sills (QFP) which appear to control the copper-gold skarn mineralization.

到目前为止,廷卡在Silvia NW的勘探活动主要集中在位于目标区西南端的A区的夕卡岩详细测绘和采样(图2)。这些夕卡岩赋存于白垩纪朱马沙组,这是一个厚(>2公里)的石灰岩序列,构成了秘鲁中部褶皱冲断带的主要部分,也是秘鲁几个主要的夕卡岩矿床(包括安塔米纳)的所在地。A区石灰岩受石英长石斑岩脉岩和岩床(QFP)侵入,似乎控制了铜-金夕卡岩成矿作用。

Skarn occurs both in the limestone (as exoskarn) and in QFP (as endoskarn) over an apparently continuous area of approximately 400 metres x 100 metres (see Figure 3). There is widespread scree cover in-between outcrops of skarn limiting outcrop (Figures 4 & 5). Tinka geologists believe that the skarn mineralization could continue over a larger area beneath the scree on the lower slopes and floor of the valley. On the edges of the outcropping skarn zones, limestones show minor to weak skarn development and are weakly mineralized or unmineralized. Limestone outside of the skarn zones have developed localised hornfels and minor skarn veining.

夕卡岩既存在于石灰岩中(作为外生岩溶),也存在于QFP中(作为内生岩溶),其表面上连续的面积约为400米x 100米(见图3)。夕卡岩露头之间有广泛的碎石覆盖,限制了露头(图4和图5)。丁卡地质学家认为,矽卡岩成矿作用可能会在山谷下坡和谷底的碎石下更大的区域内继续存在。在出露的矽卡岩带边缘,石灰岩表现为弱-弱夕卡岩发育,矿化弱或未矿化。夕卡岩带外的石灰岩发育了局部角砾岩和少量的矽卡岩脉。

The skarns are dominated by green garnets with or without magnetite and other calc-silicates (Figure 6). Sulphides in the outcrops are common (typically partially oxidised) and dominated by chalcopyrite and pyrite with minor covellite, chalcocite, and malachite.

夕卡岩以绿色石榴石为主,有或没有磁铁矿和其他钙硅酸盐(图6)。露头中的硫化物很常见(通常是部分氧化),以黄铜矿和黄铁矿为主,还有少量的黑铜矿、辉铜矿和孔雀石。

Table 1 below highlights the copper-gold trench sampling results presented in this release (also highlighted in Figure 3) along with selected other metals. Table 2 is a summary of the surface samples by rock type. Zinc, along with silver, is anomalous in many of the samples while arsenic is not significant.

Notes on sampling and assaying

关于取样和化验的几点注意事项

Trenches were dug up to a depth of 1 metre, where possible, across areas of outcrop (partially weathered) to test the grade of skarn and adjacent limestones and intrusions. Trench samples are continuous samples collected with hammer and chisel over 1 to 2 metre intervals. In areas of sporadic outcrop, samples are taken as semi-continuous rock chips. Tinka believes that the samples are representative of the outcrop and non-selective. Samples were bagged and labelled in the field. Samples were sent to Certimin laboratory in Lima where samples were dried, crushed to 90% passing 2mm, then 1 kg pulverized to 85% passing 75 microns. Gold was analysed by fire assay on 30 g (method G0108) and multi-element analysis by ICP using multi-acid digestion (method G0176). Gold assays above 10 g/t Au were re-assayed by a high-grade fire assay method and a gravimetric finish (method G0014). Copper assays over 1% Cu were re-assayed by atomic absorption (method G0039). Standards and blanks were not inserted by Tinka but were inserted at the laboratory.

在可能的情况下,挖掘深达1米的战壕,横跨露头区域(部分风化),以测试夕卡岩和邻近的石灰岩和侵入体的等级。沟槽样品是用锤子和凿子在1到2米的间隔内连续采集的样品。在零星露头地区,取样品为半连续岩屑。丁卡认为,这些样本代表了露出地面的情况,是非选择性的。样品在田间被装袋并贴上标签。样品被送到利马Certimin实验室,在那里样品干燥,经过2 mm粉碎到90%,然后通过75微米将1公斤粉碎到85%。金的分析采用30g火试金法(G0108法)和多酸消化ICP多元素分析法(G0176法)。用高级火试金法和重量法重新测定10g/tAu以上的金含量(方法G0014)。用原子吸收法重新测定铜含量超过1%的铜(方法G0039)。标准和空白不是由丁卡插入的,而是在实验室插入的。

前瞻性陈述:本新闻稿中的某些信息包含适用证券法定义的前瞻性陈述和前瞻性信息(统称为“前瞻性陈述”)。除有关历史事实的陈述外,所有陈述均为前瞻性陈述。前瞻性陈述基于Tinka的信念和期望,以及Tinka管理层所做的假设和目前可获得的信息。此类陈述反映了与某些因素有关的当前风险、不确定性和假设,这些因素包括但不限于:计划工作方案和结果与预期不同的时间安排;取得成果的延迟;股票市场的变化;与未来所需融资的可获得性和成本有关的不确定性;设备故障、意外的地质条件;资源估计或金属回收的不精确性;未来开发举措的成功;竞争和经营业绩;环境和安全风险;公司对Ayawilca项目PEA的期望;公司继续支持采矿项目开发和运营的政治环境。这些风险包括:对公司或整个矿业的负面宣传的风险;与病毒和传染病爆发(包括新型新冠肺炎病毒)相关的威胁;获得地方当局必要许可和批准的延误或未能获得必要许可和批准的风险;社区协议和关系;以及其他开发和运营风险。如果这些风险或不确定性中的任何一个或多个成为现实,或者任何潜在的假设被证明是错误的, 实际结果可能与本文描述的结果大不相同。尽管廷卡公司认为前瞻性陈述中固有的假设是合理的,但前瞻性陈述并不能保证未来的业绩,因此,由于这些陈述固有的不确定性,不应过分依赖这些陈述。除非适用的证券法另有要求,否则廷卡公司没有任何更新任何前瞻性陈述的意图或义务。
