這礦山在中國湖南準備出售This mine in Hunan, China, is ready for sale.

 這個礦山在湖南,我不知道說上市公司如果買下這個東西有沒有辦法作價然後那個變成公司的財報


好的,這是一份根據您提供的儲量數據,並結合2012年底左右的典型礦產品市場價格,所整理的礦產價值估算報告。


重要聲明與前提假設:


1. 價格基準: 本報告採用的是2012-2013年期間的礦產品平均價格作為估算基準。當前的市場價格與當時有巨大差異,此報告僅反映當時的潛在價值,而非當前價值。

2. 非精確估值: 這是一個「毛價值」或「原地價值」的初步估算,未考慮以下關鍵成本因素:

   · 開採成本: 採礦、選礦、運輸等所有操作成本。

   · 加工和冶煉成本: 將精礦冶煉成金屬的成本,以及冶煉回收率損失。

   · 稅費和權利金: 需向政府繳納的各種稅費。

   · 折現率與時間價值: 資源量(333)的經濟性不確定性更高,開採需要時間。

   · 可採儲量:「保有資源量」不等於「可採儲量」,在開採過程中會有損失。

3. 資源類別說明:

   · 122b、332: 可信度較高,其價值可採用較高的係數(本估算中按100%計算)。

   · 333: 為推斷資源量,地質可靠度較低,在初步經濟評估中通常會打一個折扣,業內常使用 0.5 ~ 0.7 的係數。為使估算更貼近實際,本報告對333類資源採用 0.6(60%) 的係數進行估算。

礦產資源潛在價值估算報告(截至2012年底)


估算基礎: 假設2012年底市場價格如下(均為約數):


· 錫: 20,000 美元/噸

· 鉛: 2,200 美元/噸

· 鋅: 2,000 美元/噸

· 銀: 30 美元/盎司 (注意: 需要換算成美元/噸)

· 鎢: 30,000 美元/噸

· 錳礦石: 5 美元/噸度 (即每1%的錳含量每噸礦石價值5美元)


一、 錫資源價值估算


· 122b類 Sn金屬量: 19,065 噸

  · 價值 = 19,065 噸 * 20,000 美元/噸 = 381,300,000 美元

· 333類 Sn金屬量: 63,767 噸

  · (考慮可信度係數) 可視為 63,767 噸 * 0.6 = 38,260 噸

  · 價值 = 38,260 噸 * 20,000 美元/噸 = 765,200,000 美元

· 錫資源總潛在價值:

  · 381,300,000 + 765,200,000 = 1,146,500,000 美元

  · 約 11.47 億美元


二、 鉛鋅資源價值估算


· 332類 Pb金屬量: 19,885 噸

  · 價值 = 19,885 噸 * 2,200 美元/噸 = 43,747,000 美元

· 333類 Pb金屬量: 62,792 噸

  · (考慮可信度係數) 可視為 62,792 噸 * 0.6 = 37,675 噸

  · 價值 = 37,675 噸 * 2,200 美元/噸 = 82,885,000 美元

· 332類 Zn金屬量: 10,762 噸

  · 價值 = 10,762 噸 * 2,000 美元/噸 = 21,524,000 美元

· 333類 Zn金屬量: 25,317 噸

  · (考慮可信度係數) 可視為 25,317 噸 * 0.6 = 15,190 噸

  · 價值 = 15,190 噸 * 2,000 美元/噸 = 30,380,000 美元

· 鉛鋅資源總潛在價值:

  · 43,747,000 + 82,885,000 + 21,524,000 + 30,380,000 = 178,536,000 美元

  · 約 1.79 億美元


三、 銀資源價值估算


· 首先進行單位換算:1噸 = 32,150.7 金衡盎司

· 333類 Ag金屬量: 22 噸 = 22 * 32,150.7 ≈ 707,315 盎司

· (考慮可信度係數) 可視為 707,315 盎司 * 0.6 = 424,389 盎司

· 銀資源潛在價值:

  · 424,389 盎司 * 30 美元/盎司 = 12,731,670 美元

  · 約 1273 萬美元


四、 鎢資源價值估算


· 333類 WO3金屬量: 20 噸

· (考慮可信度係數) 可視為 20 噸 * 0.6 = 12 噸

· 鎢資源潛在價值:

  · 12 噸 * 30,000 美元/噸 = 360,000 美元

  · 約 36 萬美元


五、 錳礦石資源價值估算


· 332類礦石量: 15.1 萬噸,Mn品位15.63%

  · 價值 = 151,000 噸 * 15.63% * 5 美元/噸度 = 1,180,065 美元

· 333類礦石量: 61.9 萬噸,Mn品位13.92%

  · (考慮可信度係數) 可視為 619,000 噸 * 0.6 = 371,400 噸

  · 價值 = 371,400 噸 * 13.92% * 5 美元/噸度 = 2,584,944 美元

· 錳礦石資源總潛在價值:

  · 1,180,065 + 2,584,944 = 3,765,009 美元

  · 約 377 萬美元

總價值匯總


礦種 潛在價值(美元) 備註

錫 1,146,500,000 主要價值來源,佔比極高

鉛鋅 178,536,000 重要的附帶價值

銀 12,731,670 

鎢 360,000 價值較小

錳 3,765,009 價值較小

總計 約 13.42 億美元 


結論與說明


根據以上估算,截至2012年12月31日,該採礦權範圍內保有的礦產資源,其潛在的總毛價值大約為 13.42 億美元。


· 核心價值: 該礦床的核心價值毫無疑問來自錫金屬,其價值佔總價值的85%以上。

· 重要組成部分: 鉛鋅金屬提供了可觀的附加價值,約佔總值的13%。

· 次要價值: 銀、鎢、錳的價值在總盤子中佔比很小,可視為伴生或共生產品。


再次強調,這是一個非常初步的、基於多項假設的估算。 要獲得真實的經濟價值,必須進行詳細的可行性研究,並扣除所有預期的成本和損失。實際的礦權交易價值會遠低於此估算的「毛價值」

Okay, this is a mineral valuation report based on the reserve data you provided, combined with typical mineral market prices around the end of 2012.


Important Disclaimers and Assumptions:


1. Price Benchmark: This report uses the average mineral price during 2012-2013 as the valuation benchmark. Current market prices differ significantly from those at the time; this report reflects the potential value at that time, not the current value.


2. Inaccurate Valuation: This is a preliminary estimate of "gross value" or "value in place" and does not consider the following key cost factors:


· Mining Costs: All operational costs including mining, beneficiation, and transportation.


· Processing and Smelting Costs: The cost of smelting the concentrate into metal, plus smelting recovery losses.


· Taxes and Royalty Costs: Various taxes payable to the government.


· Discount Rate and Time Value: The economic uncertainty of the resource quantity (333) is higher, and extraction takes time.


• Recoverable Reserves: "Proven resources" are not equal to "recoverable reserves," as losses occur during extraction.


3. Resource Category Explanation:


• 122b, 332: Higher reliability; their value can be calculated using a higher coefficient (calculated at 100% in this estimate).


• 333: Inferred resource quantity; lower geological reliability. A discount is usually applied in preliminary economic assessments; a coefficient of 0.5 to 0.7 is commonly used in the industry. To make the estimate more realistic, this report uses a coefficient of 0.6 (60%) for resource category 333.

· Value = 371,400 tons * 13.92% * 5 USD/ton-degree = 2,584,944 USD


· Total potential value of manganese ore resources:


· 1,180,065 + 2,584,944 = 3,765,009 USD


· Approximately 3.77 million USD

Total Value Summary


Mineral Type Potential Value (USD) Remarks


Tin 1,146,500,000 Main source of value, extremely high proportion


Lead & Zinc 178,536,000 Important incidental value


Silver 12,731,670


Tungsten 360,000 Less valuable


Manganese 3,765,009 Less valuable


Total Approximately US$1.342 billion


Conclusion and Explanation


Based on the above estimates, as of December 31, 2012, the potential gross value of the mineral resources within this mining right is approximately US$1.342 billion.


• Core Value: The core value of this deposit undoubtedly comes from tin, accounting for over 85% of the total value.


• Important Components: Lead and zinc provide considerable added value, accounting for approximately 13% of the total value.


• Secondary Value: Silver, tungsten, and manganese represent a small percentage of the total value and can be considered associated or symbiotic products.


It is important to reiterate that this is a very preliminary estimate based on multiple assumptions. To obtain the true economic value, a detailed feasibility study must be conducted, and all anticipated costs and losses must be deducted. The actual transaction value of the mining rights will be significantly lower than this estimated "gross value."
