P1、P2、P3指SEC、SPE的储量分类范畴。

按照地质认识程度，资源分为4大类产量（production），储量（reserve），潜在资源（contingent resource）和远景资源（prospective resource）其中，储量分3级，即P1：证实储量（proved reserves）P2：概算储量（probable reserves）P3：可能储量（possible reserves）我们常说的1P=P1，2P=P1+P2，3P=P1+P2+P31C表示条件潜在储量的低估算量方案。

2C表示条件潜在储量的最佳估算量方案。

3C表示条件潜在储量的高估算量方案。

1P等同于证实储量；表示储量的低估算量方案。

2P等同于证实储量与可能储量的和；表示储量的最佳估算量方案。

3P等同于证实储量加上可能储量加上潜在（可采）储量的和；表示储量的高估算量方案。

探明的P1 储量1)探明储量是已完成有评价探井、测井、岩心、生产测试等资料，储量参数取全或基本取全并被探明了的储量。

该储量是编制油（气）田开发方案、进行油（气）田开发建设投资决策和油（气）田开发分析的重要基础。

探明储量又分为已开发(Proved Developed)，简称P1的PD储量类型；未开发（Proved Undeveloped），简称P1 的PUD 储量类型。

探明可采储量实际采出的油量将等于或超过评估值的概率至少有90%。

2)已开发PD 的探明储量是指根据开发方案要求已经钻完开发井及已建成地面集输工程的储量。

已开发探明的可采储量根据生产情况又分为已生产PDP（ProvedDeveloped Producing）和未生产PDNP (Proved Developed Non producing)的储量。

已开发未生产PDNP 的储量是指在评估时已射孔但尚未投产井层的储量；由于市场条件或管理要求关掉井层的储量；管外储量，亦即是在现有生产井中可以补孔或重新完井可获得有关层段的可采储量。

一、矿床勘查类型1、确定勘查类型的主要地质依据。

依据矿体规模、矿体形态的复杂程度、构造复杂程度和矿石有用组分分布均匀程度，将勘查类型划分为三个类型。

其中第Ⅰ勘查类型为简单型，矿体规模为大型，矿体形态和构造变化均简单，矿石有用组分分布均匀。

第Ⅱ类勘查类型为中等型，矿体规模为中等，矿体形态和构造变化中等，矿石有用组分分布较均匀。

第Ⅲ类勘查类型为复杂型，矿体规模小型，矿体形态和构造变化复杂。

采矿权和探矿权在资产价值上没有区别——兼谈某些矿产资源管理名词的完善咨询委员李裕伟对于同一个矿产地，说起采矿权，人们总觉得它的价值要高于探矿权，其实这是一种误解。

在法律的层面上，探矿权和采矿权是有区别的；但在经济的层面上，探矿权与采矿权并无区别。

首先我们需要引入矿产资源资产（以下简称矿资产）的概念，它同这宗资产是在探矿权名下还是在采矿权名下无关。

譬如说有一宗煤炭资源的矿产资源资产，经评估其价值为2000万元，那么不论该资产是作为探矿权出让，还是作为采矿权出让，其价值均应为2000万元。

正是因为在我国的矿产资源法规体系中没有引入矿资产的概念，而是用矿业权代表矿资产，具体讲是用探矿权和采矿权代表矿资产，这就使得“矿业权”一词具承担了双重责任：其一是矿产资源的法律保障，其二是矿产资源的资产实物。

基于这种把矿产资源的法律属性和经济属性混合成一个词的现实，于是“矿业权”既作为一种权属在政府部门审批，又作为一种资产在市场上转让，但到底在什么情况下矿业权是权力的代表，什么时候是资产的代表，人们很难说得清楚。

在许多情况下是其权力属性与资产属性混在一起，从而导致政府行为与市场行为混在一起，不利于政府清晰地执行其矿产资源的行政审批和资产监管职能。

国外矿业权和矿产资源资产是两个概念，用两个名词来表示。

矿业权（mining title 或 mining right）是对某一特定矿产地开展矿业活动的法律保障；矿资产（mineral property）是在该矿产地中的矿产资源实物，包括资源/储量、矿床、矿体、矿化、异常、远景区等，对它们应进行了圈定和评估。

矿资产有两个基本权属主体：所有者和使用者。

在我国，所有者是国家，使用者是企业。

按照国外惯例，从矿业公司（使用者）的角度，矿资产等于该矿产地的全部价值减去权利金及其他形式的矿产资源所有者提取部分。

假定该矿产地的全部价值为Q，国家作为所有者占有P，矿资产R=Q-P。

R是矿资产，而矿业权是对R进行法律保护。

Mineral Reservesand Mineral Resources Defi nitionsA mineral resource is a concentration or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quantity and of such a grade or quality that it has reasonable prospects for economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specifi c geological evidence and knowledge. Mineral resources are sub-divided, in order of increasing geological confi dence,into inferred, indicated and measured categories.An inferred mineral resource is that part of a mineral resource for which quantity and grade or quality can be estimated on the basis of geological evidence and limited sampling and reasonably assumed, but not verifi ed, geological and grade continuity. The estimate is based on limited information and sampling gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes.An indicated mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics, can be estimated with a level of confi dence suffi cient to allow the appropriate application of technical and economic parameters, to support mine planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable exploration and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough for geological and grade continuity to be reasonably assumed.A measured mineral resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and physical characteristics are so well established that they can be estimated with confi dence suffi cient to allow the appropriate application of technical and economic parameters, to support production planning and evaluation of the economic viability of the deposit. The estimate is based on detailed and reliable explo r ation, sampling and testing information gathered through appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes that are spaced closely enough to confi rm both geological and grade continuity.Mineral resources, which are not mineral reserves, do not have demonstrated economic viability.A mineral reserve is the economically mineable part of a measured or indicated mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justifi ed.A mineral reserve includes diluting materials and allowances for losses that may occur when the materialis mined. Mineral reserves are sub-divided in order of increasing confi dence into probable mineral reserves and proven mineral reserves. A probable mineral reserve is the economically mineable part of an indicated and, in some circumstances, a measured mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction can be justifi ed.A proven mineral reserve is the economically mineable part of a measured mineral resource demonstrated by at least a preliminary feasibility study. This study must include adequate information on mining, processing, metallurgical, economic and other relevant factors that demonstrate, at the time of reporting, that economic extraction is justifi ed.The tables on the next seven pages set forth Barrick’s interest in the total proven and probable gold and copper reserves and in the total measured and indicated gold, copper and nickel resources and certain related information at each property. For further details of proven and probable mineral reserves and measured, indicated and inferred mineral resources by category, metal and property, see pages 182 to 188.The Company has carefully prepared and verifi ed the mineral reserve and mineral resource fi gures and believes that its method of estimating mineral reserves has been verifi ed by mining experience. These fi gures are estimates, however, and no assurance can be given that the indicated quantities of metal will be produced. Metal price fl uctuations may render mineral reserves containing relatively lower grades of mineralization uneconomic. Moreover, short-term operating factors relating to the mineral reserves, such as the need for orderly development of ore bodies or the processing of new or different ore grades, could affect the Company’s profi tability in any particular accounting period.181Summary Gold Mineral Reserves and Mineral Resources1,2,3For the years ended December 312011 2010OuncesTons Grade Ounces TonsGradeBased on attributable ounces (000s) (oz/ton) (000s) (000s)(000s)(oz/ton)North AmericaGoldstrike Open Pit (proven and probable)97,325 0.096 9,34295,865 0.101 9,656(mineral resource)4,612 0.032 1474,694 0.037 173Goldstrike Underground (proven and probable)11,895 0.255 3,03510,872 0.272 2,958(mineral resource)6,077 0.301 1,8286,771 0.298 2,020 Goldstrike Property Total (proven and probable)109,220 0.113 12,377106,737 0.118 12,614(mineral resource)10,689 0.185 1,97511,465 0.191 2,193 Pueblo Viejo (60.00%) (proven and probable)188,729 0.080 15,173168,417 0.084 14,195(mineral resource)120,194 0.055 6,59796,807 0.059 5,675Cortez (proven and probable)306,879 0.047 14,488317,081 0.046 14,494(mineral resource)54,391 0.069 3,75760,463 0.071 4,320Red Hill – Goldrush (proven and probable)– – –– – –(mineral resource)11,221 0.113 1,273– – – Bald Mountain (proven and probable)307,162 0.017 5,102246,711 0.019 4,748(mineral resource)123,191 0.013 1,623151,944 0.011 1,680 Turquoise Ridge (75.00%) (proven and probable)11,986 0.442 5,2949,254 0.456 4,224(mineral resource)62,394 0.122 7,64164,219 0.131 8,415Round Mountain (50.00%) (proven and probable)82,688 0.017 1,41173,017 0.018 1,319(mineral resource)83,420 0.016 1,33850,865 0.022 1,107South Arturo (60.00%) (proven and probable)28,237 0.050 1,39827,358 0.051 1,391(mineral resource)21,482 0.039 82816,041 0.043 692Ruby Hill (proven and probable)16,778 0.058 97817,182 0.065 1,122(mineral resource)107,626 0.021 2,24561,530 0.023 1,390Hemlo (proven and probable)16,620 0.069 1,13918,388 0.074 1,362(mineral resource)4,735 0.087 4104,184 0.071 299 Marigold Mine (33.33%) (proven and probable)77,285 0.015 1,19447,843 0.016 775(mineral resource)10,977 0.012 13526,842 0.014 387Golden Sunlight (proven and probable)8,932 0.055 4879,649 0.056 539(mineral resource)716 0.041 291,231 0.047 58Donlin Gold (50.00%) (proven and probable)– – –– – –(mineral resource)298,358 0.065 19,503322,485 0.060 19,357South AmericaCerro Casale (75.00%) (proven and probable)990,088 0.018 17,4341,002,722 0.017 17,377(mineral resource)245,990 0.010 2,494199,842 0.012 2,376Pascua-Lama (proven and probable)424,117 0.042 17,861423,931 0.042 17,845(mineral resource)269,930 0.025 6,734231,590 0.027 6,260Veladero (proven and probable)481,153 0.022 10,558483,181 0.023 11,291(mineral resource)44,029 0.011 46451,130 0.012 600Lagunas Norte (proven and probable)214,418 0.029 6,151210,104 0.031 6,618(mineral resource)35,164 0.014 50540,529 0.019 756Pierina (proven and probable)67,865 0.011 77159,947 0.013 791(mineral resource)10,243 0.013 13218,288 0.015 2731.

Resources which are not reserves do not have demonstrated economic viability.187Mineral Reserves and Resources Notes1. Mineral reserves (“reserves”) and mineral resources (“resources”) have been calculated as at December 31, 2011 in accordance with National Instrument43-101 as required by Canadian securities regulatory authorities. For United States reporting purposes, Industry Guide 7, (under the Securities and Exchange Act of 1934), as interpreted by Staff of the SEC, applies different standards in order to classify mineralization as a reserve. Accordingly, for U.S. reporting purposes, approximately 2.15 million ounces of reserves at Pueblo Viejo (Barrick’s 60% interest) is classified as mineralized material. In addition, while the terms “measured”, “indicated” and “inferred” mineral resources are required pursuant to National Instrument 43-101, the U.S. Securities and Exchange Commission does not recognize such terms. Canadian standards differ significantly from the requirements of the U.S. Securities and Exchange Commission, and mineral resource information contained herein is not comparable to similar information regarding mineral reserves disclosed in accordance with the requirements of the U.S. Securities and Exchange Commission. U.S. investors should understand that “inferred” mineral resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. In addition, U.S. investors are cautioned not to assume that any part or all of Barrick’s mineral resources constitute or will be converted into reserves. Calculations have been prepared by employees of Barrick, its joint venture partners or its joint venture operating companies, as applicable, under the supervision of Rick Sims, Senior Director, Resources and Reserves of Barrick, Chris Woodall, Senior Director, Mining of Barrick and John Lindsay, Senior Director Metallurgy, of Barrick. Except as noted below, reserves have been calculated using an assumed long-term average gold price of $US 1,200 ($Aus.1,330) per ounce, a silver price of $US 22.00 per ounce, a copper price of $US 2.75 per pound and exchange rates of 1.0 $Can/$US and 0.90 $US/$Aus. Reserves at Plutonic have been calculated using an assumed long-term average gold price of $US 1,250. Reserve calculations incorporate current and/or expected mine plans and cost levels at each property. Varying cut-off grades have been used depending on the mine and type of ore contained in the reserves. Barrick’s normal data verification procedures have been employed in connection with the calculations. Resources as at December 31, 2011 have been estimated using varying cut-off grades, depending on both the type of mine or project, its maturity and ore types at each property. For a breakdown of reserves and resources by category and for a more detailed description of the key assumptions, parameters and methods used in calculating Barrick’s reserves and resources, see Barrick’s most recent Annual Information Form/Form 40-F on file with Canadian provincial securities regulatory authorities and the U.S. Securities and Exchange Commission.2. In November 2011, the Government of the Province of Balochistan rejected the application for a mining lease in respect of the Reko Diq project. TethyanCopper Company (“TCC”) has commenced international arbitration proceedings asserting, among other things, that its local operating subsidiary is legally entitled to the mining lease subject only to “routine” government requirements.

（特约专稿：李裕伟）边界品位确定方法及其在矿产勘查中的应用导读边界品位是估计矿产资源量和储量的关键参数，用于区分矿石和岩石。

一个符合矿床开发技术经济特征的边界品位，将为采矿项目带来应有的利润。

常用的边界品位确定方法有盈亏平衡点法、演进法和蓝氏法。

盈亏平衡点法简单易行，体现了成本-价格-利润之间的基本规律，在矿产勘查、矿山项目可行性研究和矿山生产阶段均可使用。

演进法和蓝氏法细化了经济技术因素，适合在可行性研究与矿山生产阶段使用。

本文在一般介绍各种边界品位估计方法的基础上，重点阐述盈亏平衡点法在矿产勘查中的应用。

本文引用信息李裕伟，边界品位确定方法及其在矿产勘查中的应用[J].中国国土资源经济,2022（03）:04-15边界品位（cut off grade）是矿产勘查、矿山项目可行性研究、矿山设计和矿山生产中的一个重要技术概念。

在价格不变的条件下，一个经勘查发现的矿化体是不是矿，有多少矿，平均品位是多少，全凭边界品位“一锤定音”。

有了边界品位，才有了矿的一切；没有了边界品位，就没有了矿的一切。

因此，边界品位在矿产勘查中“一言九鼎”。

对如何确定边界品位，必须遵循矿业经济规律，彰显科学依据。

首先，要搞清楚边界品位是一个什么性质的参数。

对此不外有两种可能：一是资源性质的参数，二是经济性质的参数。

从表面上看，边界品位确实是资源性质的参数，因为它表述的对象是资源量和储量；但从本质上看，边界品位是一个经济指标，矿业项目是否盈利，盈利多少，全靠对它的调节来确定。

边界品位对市场和成本的灵敏度极高，在矿产品价格为5万元/吨时不盈利，到5.5万元/吨时就盈利了；在采选冶成本为80元/吨时不盈利，到85元/吨时就盈利了。

因此，要从经济的角度来确定边界品位的指标值。

边界品位是一个决定矿石和废石界限的指标：边界品位以上是矿石，以下是废石。

决定这个指标有两个核心因素：成本和价格。

当价格固定时，成本上升则边界品位提高，成本下降则边界品位降低；当成本固定时，价格上升则边界品位降低，价格下降则边界品位提高。

世界主要矿物资源的储备和开采情况摘要世界经济的高速发展致使资源的消耗不断增加,并已经引起某些资源的供求失衡,价格上涨。

随着世界资源储量同需求的矛盾进一步发展,资源将在诸生产要素中的地位上升。

对此,不少国家采取了多种应对措施:一是提高资源的利用效率,降低消耗;二是更加重视资源的科学开发;三是通过协调销售策争取最大经济利益;四是加强短缺资源的战略储备;五是寻找新的替代产品。
