Vancouver, British Columbia--(Newsfile Corp. - May 1, 2023) - Provenance Gold Corp. (CSE: PAU) (OTCQB: PVGDF) (the "Company" or "Provenance") is pleased to announce that as part of its preparation for a planned Eldorado spring drilling program, the Company has plotted cross-sections and long-sections of the historic drill holes. Analysis of the cross-sections and further supporting data has produced encouraging results.

温哥华,不列颠哥伦比亚省-(Newsfile Corp.-2023年5月1日)-Provenance Gold Corp.(CSE:PAU)(OTCQB:PVGDF)(The“The”公司“或”种源“)很高兴地宣布,作为计划中的Eldorado弹簧钻探计划的一部分,公司已经绘制了历史钻孔的横截面和长截面。对横截面的分析和进一步的支持数据产生了令人鼓舞的结果。

Upon review of the cross-sections, Provenance's Project Manager, Steven Craig, stated, "Not only is the system open outward in all directions, but it's also wide open between the holes, and especially downward. Most of the holes bottomed short of 100 meters, but the holes that went deeper continued to hit thick gold zones, even to depths below 250 meters. The deeper holes often had their best mineralization below 100 meters."

在审查了横截面后,Provenance的项目经理史蒂文·克雷格说:“系统不仅向外四通八达,而且孔与孔之间也是敞开的,特别是向下。大多数孔的底部都在100米以下,但更深的孔继续击中厚厚的金矿带,甚至深到250米以下。更深的孔通常在100米以下有最好的矿化。”

The Eldorado gold property, in mining-friendly Malheur County, in Eastern Oregon, was the site of extensive historic placer mining. Although the project is in a desert environment, it has very few outcrops. The placer mining locally exposed the underlying gold-bearing bedrock. Later, historic drilling focused on the areas where placer mining had exposed the gold-mineralized bedrock, leaving much of the mineralized area still undrilled.

Eldorado金矿位于俄勒冈州东部采矿友好的马赫尔县,是大量历史砂矿开采的所在地。虽然该项目位于沙漠环境中,但露头很少。当地的砂矿开采暴露了下面的含金基岩。后来,历史性的钻探集中在砂矿开采暴露了金矿化基岩的地区,留下了大部分矿化区仍未钻探。

The gold mineralization is associated with a diorite intrusive that hosts most of the gold. The deposit is a porphyry-style gold system that additionally contains breccia zones that carry local high-grade gold values. Historic testing suggested that the property has excellent recovery characteristics because the gold came in after the sulfides, so consequently even the unoxidized rock appears to have good recovery characteristics, even using only gravity and floatation.

金矿化与赋存大部分金的闪长岩侵入岩有关。该矿床是一个斑岩型金矿系统,另外还含有携带当地高品位黄金价值的角砾岩带。历史测试表明,由于金是在硫化物之后进入的,因此该性质具有良好的回收特性,因此即使只使用重选和浮选,未氧化的岩石也表现出良好的回收特性。

In 1990, the first mineral inventory was calculated by Pincock, Alan and Holt (PAH), a reputable engineering firm that was used industry-wide for this type of work. PAH modelled 158 of the historic drill holes which identified approximately 52,896,000 tons that graded 0.578 gram per tonne gold (0.0169 ounce/t gold) at a cut-off of 0.274 gram per tonne (0.008 oz/t) in the completely open-ended gold system. The Company is aware of a second historical resource estimate that was calculated by Ican Minerals and a projected resource estimate by Ican from that included additional drilling completed between 1989 and 1997 where the tonnage and grade were substantially higher. Other than these, the Company is not aware of any more recent estimates prepared for the property. The Company is not treating any of these estimates as current mineral resources and a qualified person has not done sufficient work to classify these estimates as current mineral resources. The estimates were prepared prior to the enactment of National Instrument 43-101 and should not be relied upon for investment decisions. The purpose of presenting this information is to show that the Eldorado project has potential to hold a large mineral inventory. Provenance plans to update these historical estimates into a current resource model. Near-term work includes confirmation drilling by twinning a number of the historic holes, certifying and comparing assays between the old and new holes, validating historic hole locations, and confirming historic metallurgical test results.

1990年,第一批矿物库存由Pincock,Alan and Holt(PAH)计算,该公司是一家享有盛誉的工程公司,曾在整个行业内从事这类工作。环境保护局对158个具有历史意义的钻孔进行了建模,这些钻孔确定了大约52,896,000吨,在完全不限成员名额的黄金系统中,这些钻孔的品位为每吨0.578克黄金(0.0169盎司/吨黄金),下限为每吨0.274克黄金(0.008盎司/吨)。本公司知悉由Ican Minerals计算的第二次历史资源估计,以及Ican根据1989年至1997年期间完成的额外钻探计算得出的预测资源估计,这些额外钻探的吨位和品位大幅提高。除此之外,本公司并不知悉就该物业编制的任何较新估计。本公司并未将该等估计中的任何一项视为现有矿产资源,而一名合资格人士并未进行足够的工作以将该等估计归类为现有矿产资源。这些估计数是在颁布《国家文书43-101》之前编制的,不应作为投资决定的依据。提供这一信息的目的是表明Eldorado项目具有拥有大量矿物库存的潜力。Provenance计划将这些历史估计更新为当前的资源模型。近期工作包括通过对一些历史孔进行确认钻探、认证和比较新旧孔之间的分析、确认历史孔位置以及确认历史冶金测试结果。

Shown below are two of the cross-sections that help to illustrate the significant potential upside on the property. The horizontal depth lines are spaced 30.48 meters (100 feet) apart, with the same horizontal scale. The unmineralized intervals are shown in black and are believed to represent post-mineralization intrusive pulses or slices of rock into which mineralizing fluids did not penetrate and are commonly surrounded by mineralized rock.

下面显示的是两个横截面,有助于说明该物业的显著潜在上行空间。水平深度线的间距为30.48米(100英尺),具有相同的水平比例。未矿化间隔以黑色显示,被认为是矿化后侵入脉冲或岩片,成矿流体没有渗入其中,通常被矿化岩石包围。

The holes shown in Section A-A' bottom in mineralization which continues downward an unknown distance. The green proposed holes show how Provenance plans to find the full extent of the gold mineralization at a future date. This section is similar to all other nearby sections that all have significant infill and step-out potential.

A-A段所示的洞位于矿化的底部,向下延伸了一段未知的距离。绿色的孔洞显示了出处如何计划在未来的某一天发现金矿的全部范围。此部分类似于所有其他附近的部分,这些部分都具有显著的填充和后退潜力。

Section H-H' cuts through a breccia zone that was historically chased downward for 250 meters (820 feet) with almost continuous strong gold mineralization. Note the unmineralized zone deep in the drilling was followed by another 30 meters (100 feet) of strong gold values. It is uncertain whether the hole went out the side wall of the breccia zone, which may extend even deeper. Also note there is no other deep drilling in this entire area.

H-H‘段穿过一个角砾岩带,历史上该带被向下追逐250米(820英尺),几乎连续地有强烈的金矿化。请注意,在钻探深处的未矿化区紧随其后的是另一个30米(100英尺)的强劲黄金价值。目前还不确定这个洞是否从角砾岩带的侧壁出来,角砾岩带可能延伸得更深。还要注意的是,整个地区没有其他深井钻探。

Of Particular Note:

特别要注意的是:

  • All the colored (non-black or grey) drill hole sections represent rock grades that would normally be mined in an open pit. Current bulk open-pit mines commonly average about 0.015 ounces of gold per ton (0.5 g/t). Based on non-compliant historic assays, Eldorado in bulk, averages better than 0.02 ounces of gold per ton (almost 0.7 g/t) with much higher-grade zones. Current mines are leaching rock that is as low as 0.1 g/t gold.
  • Most of the historic drill holes were less than 100 meters (328 feet) deep, yet the sections show mineralization continuing to even deeper than 250 meters (820 feet).
  • The higher-grade mineralization is associated with breccia zones (likely breccia pipes) such as the one containing the high-grade area shown in section H-H'. It appears the historic drilling focused on that breccia pipe because it was exposed on the surface. Surface geology and the various cross-sections suggest the presence of additional breccia pipes that aren't yet exposed or drilled.
  • When the pre-NI 43-101 historic work was done, proven reserves were limited to within 7.6 meters (25 feet) and probable reserves were limited to 15.24 meters (50 feet) from the drill hole. The cross-sections show that the majority of the projected mineralization is beyond those historic distance controls.
  • Most of the drilling was reverse-circulation (RC) drilling. Often, RC drilling will give lower values than core drilling under wet hole conditions. At Eldorado, abundant ground water was encountered at about 60 meters (200 feet) and the gold at Eldorado is on the surfaces of the sulfide grains where it can be washed away.
  • 所有彩色(非黑色或灰色)钻孔段代表通常在露天矿开采的岩石等级。目前的大型露天矿平均每吨(0.5g/t)含金约0.015盎司。根据不合规的历史分析,Eldorado散装黄金的平均含量高于每吨0.02盎司(几乎为0.7克/吨),矿带品位要高得多。目前的矿山正在浸出低至0.1g/t金的岩石。
  • 大多数历史悠久的钻孔深度都不到100米(328英尺),但切片显示矿化继续深入到250米(820英尺)以上。
  • 高品位矿化与角砾岩带(可能是角砾岩管道)有关,例如H-H‘段所示的高品位矿化带。历史上的钻探似乎把重点放在了角砾岩管道上,因为它暴露在地表。地表地质和不同的横截面表明,还有其他尚未暴露或钻探的角砾岩管道。
  • 当NI 43-101之前的历史性工作完成时,已探明储量被限制在7.6米(25英尺)以内,可能的储量被限制在距钻孔15.24米(50英尺)的范围内。横截面显示,大多数预测的矿化都超出了历史上的距离控制。
  • 大部分钻井为反循环(RC)钻井。通常,在湿井条件下,RC钻井比岩心钻井提供的价值更低。在Eldorado,在大约60米(200英尺)处遇到了大量的地下水,Eldorado的黄金位于硫化物颗粒的表面,在那里它可以被冲走。

Provenance will focus its upcoming drilling on beginning to verify the historic drilling, while simultaneously beginning to fill in the historic gaps and extending the mineralization downward and outward.

Provenance即将进行的钻探将专注于开始核实历史性的钻探,同时开始填补历史空白,并向下和向外延伸矿化。

"We are confident the upcoming drilling will put the project and our company on the map. This is an exciting time for us," said Provenance Chairman, Rauno Perttu.

Provenance董事长Rauno Perttu表示:“我们相信,即将进行的钻探将使该项目和我们的公司声名鹊起。这对我们来说是一个令人兴奋的时刻。”
