A practical real option methodology for the evaluation of farm-in/out joint venture agreements in mineral exploration

Although the “real option valuation” (ROV) methodology offers extremely valuable insights in optimising investment decisions in the face of uncertainty, its practical acceptance in the mining industry has until recently been slow because of its perceived computational complexity. Recent conceptual advances in the use of binomial lattices and software developments in the areas of decision trees and dynamic programming, have significantly simplified ROV analysis and made it of practical application in day-to-day financial evaluations and decisions involving uncertainty. This paper provides general background on the ROV methodology and an example of how a typical farm-in/out agreement, as a preliminary to the establishment of a joint venture (JV), can be valued as a series of sequential and compound real options. For illustrative and quality assurance purposes, a simple farm-in/out agreement is valued from the point of view of the party acquiring equity in the project (the farm-inee) using two distinct methods, i.e. (a) a binomial lattice and (b) a decision tree in combination with binomial stochastic processes, in both cases neutralising risk using the user-friendly “risk-neutral probability”. The fact that exactly the same ROV is obtained by both methods provides confidence in the modified decision tree approach, which opens up the capacity to value the more complex sequential/compound real options inherent in real-life farm-in/out agreements. The model is then modified to incorporate a number of realistic contractual conditions often encountered in typical exploration and mining farm-in/out deals. The paper demonstrates how the increased complexity of the model can be relatively easily addressed using a decision tree with dynamic programming capability.

辽宁省第四系地下水库勘察规划

通过分析辽宁省水资源的供需现状、基础地质气候条件以及重点对第四系河谷的野外实地调查,同时根据地方经济的发展趋势、地下水库的功能,论证了辽宁省地下水库开发的必要性和可行性,指出该省的下辽河平原、辽西部分山问河谷、辽西辽南的滨海河谷适宜修建地下水库,并制定了第四系地下水库勘察规划,即把辽宁省规划为5个地下水库勘察区(地下水库已勘察区或建成区、近期地下水库勘察区、中期地下水库勘察区、远期地下水库勘察区、未规划地下水库勘察区).     

香港海沙资源的勘探开发与管理

海沙开采已成为仅次于油气开采的世界第二重要海洋开采业。1980年代以来,香港政府投资1.7×10⁸港元为寻找海岸围垦填料进行了一系列的海沙勘探活动,在1828km²香港水域发现22个地点海沙资源储量7.4×10⁸m³,其中9个地点4.2×10⁸m³储量因覆盖层较厚或污染严重或海区环境特别敏感等原因被暂时搁置。1990～2002年共开采海沙2.7×10⁸m³,为形成2100hm²新土地的多项围垦工程提供了约一半的填料。基于地球物理勘探和钻探资料建立了香港海域第四纪层序和海沙产状地质模型,发现和证实了含气沉积物地震剖面的声波浑浊现象。香港政府对海沙资源进行统一勘探和统一管理,强调海沙开采的环境和生态影响评估,利用废弃的海床挖沙坑回填倾废的非污染海泥和受污染海泥。我国内地海沙勘探管理可以从中取得借鉴。     

南海北部海域油气勘探保障建设选址适宜性研究

为分析南海北部海域油气勘探保障建设选址的适宜性,在广泛研究备选区特征资料的基础上,基于层次分析法(Analytic Hierarchy Process, AHP)原理,以自然环境因素、开发环境因素、基础设施与投资情况以及其他因素作为一级评判准则,建立了包括12项二级评判准则的递进层次结构模型,并以永兴岛、赵述岛和晋卿岛作为3个假定备选区,来验证分析评价模型的有效性和可靠性。AHP评判结果显示,3个备选区的整体优劣指数依次为0.587 1, 0.212 1, 0.200 8;AHP模型的一致性比例CR值为0.020 3。通过分析和筛选影响远海油气勘探保障建设的选址因子,构建基于AHP原理的选址评价模型,可用于分析评价南海北部岛礁油气勘探保障建设选址的适宜性。     

Mineral exploration in the USSR and the USA

This article compares non-fuel mineral exploration in the USSR and the USA. It examines the organization of exploration; recent trends in the level and distribution of expenditures; exploration productivity; and planning and decision making. It shows that although the sequence of exploration stages and activities is very similar in both countries, substantial differences overshadow these similarities, largely because of different economic and political systems and mineral endowments. However, the article concludes that we still have much to learn before making a full comparison of Soviet and US exploration.
