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.

溫哥華,不列顛哥倫比亞省-(Newsfile Corp.-2023年5月1日)-Provenance Gold Corp.(CSE:PAU)(OTCQB:PVGDF)(The“The”公司“或”種源“)很高興地宣佈,作為計劃中的Eldorado彈簧鑽探計劃的一部分,公司已經繪製了歷史鑽孔的橫截面和長截面。對橫截面的分析和進一步的支持數據產生了令人鼓舞的結果。

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."

在審查了橫截面後,Provenance的專案經理史蒂文·克雷格說:“系統不僅向外四通八達,而且孔與孔之間也是敞開的,特別是向下。大多數孔的底部都在100米以下,但更深的孔繼續擊中厚厚的金礦帶,甚至深到250米以下。更深的孔通常在100米以下有最好的礦化。”

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金礦位於俄勒岡州東部採礦友好的馬赫爾縣,是大量歷史砂礦開採的所在地。雖然該專案位於沙漠環境中,但露頭很少。當地的砂礦開採暴露了下面的含金基岩。後來,歷史性的鑽探集中在砂礦開採暴露了金礦化基岩的地區,留下了大部分礦化區仍未鑽探。

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.

金礦化與賦存大部分金的閃長巖侵入岩有關。該礦床是一個斑岩型金礦系統,另外還含有攜帶當地高品位黃金價值的角礫巖帶。歷史測試表明,由於金是在硫化物之後進入的,因此該性質具有良好的回收特性,因此即使只使用重選和浮選,未氧化的岩石也表現出良好的回收特性。

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,第一批礦物庫存由Pincock,Alan and Holt(PAH)計算,該公司是一家享有盛譽的工程公司,曾在整個行業內從事這類工作。環境保護局對158個具有歷史意義的鑽孔進行了建模,這些鑽孔確定了大約52,896,000噸,在完全不限成員名額的黃金系統中,這些鑽孔的品位為每噸0.578克黃金(0.0169盎司/噸黃金),下限為每噸0.274克黃金(0.008盎司/噸)。本公司知悉由Ican Minerals計算的第二次歷史資源估計,以及Ican根據1989年至1997年期間完成的額外鑽探計算得出的預測資源估計,這些額外鑽探的噸位和品位大幅提高。除此之外,本公司並不知悉就該物業編制的任何較新估計。本公司並未將該等估計中的任何一項視為現有礦產資源,而一名合資格人士並未進行足夠的工作以將該等估計歸類為現有礦產資源。這些估計數是在頒佈《國家文書43-101》之前編制的,不應作為投資決定的依據。提供這一資訊的目的是表明Eldorado專案具有擁有大量礦物庫存的潛力。Provenance計劃將這些歷史估計更新為當前的資源模型。近期工作包括通過對一些歷史孔進行確認鑽探、認證和比較新舊孔之間的分析、確認歷史孔位置以及確認歷史冶金測試結果。

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.

下面顯示的是兩個橫截面,有助於說明該物業的顯著潛在上行空間。水準深度線的間距為30.48米(100英尺),具有相同的水準比例。未礦化間隔以黑色顯示,被認為是礦化後侵入脈衝或巖片,成礦流體沒有滲入其中,通常被礦化岩石包圍。

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段所示的洞位於礦化的底部,向下延伸了一段未知的距離。綠色的孔洞顯示了出處如何計劃在未來的某一天發現金礦的全部範圍。此部分類似於所有其他附近的部分,這些部分都具有顯著的填充和後退潛力。

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‘段穿過一個角礫巖帶,歷史上該帶被向下追逐250米(820英尺),幾乎連續地有強烈的金礦化。請注意,在鑽探深處的未礦化區緊隨其後的是另一個30米(100英尺)的強勁黃金價值。目前還不確定這個洞是否從角礫巖帶的側壁出來,角礫巖帶可能延伸得更深。還要注意的是,整個地區沒有其他深井鑽探。

Of Particular Note:

特別要注意的是:

  • 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)鑽孔段代表通常在露天礦開採的岩石等級。目前的大型露天礦平均每噸(0.5g/t)含金約0.015盎司。根據不合規的歷史分析,Eldorado散裝黃金的平均含量高於每噸0.02盎司(幾乎為0.7克/噸),礦帶品位要高得多。目前的礦山正在浸出低至0.1g/t金的岩石。
  • 大多數歷史悠久的鑽孔深度都不到100米(328英尺),但切片顯示礦化繼續深入到250米(820英尺)以上。
  • 高品位礦化與角礫巖帶(可能是角礫巖管道)有關,例如H-H‘段所示的高品位礦化帶。歷史上的鑽探似乎把重點放在了角礫巖管道上,因為它暴露在地表。地表地質和不同的橫截面表明,還有其他尚未暴露或鑽探的角礫巖管道。
  • 當NI 43-101之前的歷史性工作完成時,已探明儲量被限制在7.6米(25英尺)以內,可能的儲量被限制在距鑽孔15.24米(50英尺)的範圍內。橫截面顯示,大多數預測的礦化都超出了歷史上的距離控制。
  • 大部分鑽井為反迴圈(RC)鑽井。通常,在濕井條件下,RC鑽井比岩心鑽井提供的價值更低。在Eldorado,在大約60米(200英尺)處遇到了大量的地下水,Eldorado的黃金位於硫化物顆粒的表面,在那裡它可以被沖走。

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即將進行的鑽探將專注於開始核實歷史性的鑽探,同時開始填補歷史空白,並向下和向外延伸礦化。

"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董事長Rauno Perttu表示:“我們相信,即將進行的鑽探將使該專案和我們的公司聲名鵲起。這對我們來說是一個令人興奮的時刻。”
