There is no need for metal ores to be processed or sold in the Philippines. However, the Philippine authorities review all sales and exports of minerals or mineral products, including the terms of all sales obligations. The government must be informed when a marketing contract or sales contract is entered into with foreign and local buyers. It is possible that a mineral right owner will sell and sell a royalty on oil and gas rights, while the other mineral rights are maintained. In this case, the oil lease that expires, its buyer has nothing, and the mineral owner still owns the minerals. What is the classification system used by the mining industry to report mineral resources and mineral reserves? Are there any legal provisions for tax stabilization or are tax stabilization agreements in place? At the end of the disposable income tax leave under current legislation, the holder must pay the income tax provided by the NIRC. The contractor is also responsible for excise on mineral products and VAT under the NIRC and Philippine customs and customs duties. Finally, the contractor is also responsible for the local business tax and property tax under the local government code. In a report commissioned by the Federal Institute of Earth Sciences and Commodities (BGR) at the request of the Federal Ministry of Economic Cooperation and Development (BMZ), the CCSI examined the different types of legal systems applicable to mining projects in 18 countries in order to gain a better understanding of mining operations granted and negotiated under various mining regimes. CCSI compared the provisions of 30 mining contracts from 13 countries, analyzed a selection of mining-related legislation in 18 countries, and studied the experience of mining contract negotiations through dozens of interviews with experts, government officials, business representatives and members of civil society organizations. Uniform discounts, sometimes called ”simple fee” or ”Unified Tenure,” mean that surface and mineral rights are not separated. The duration of an EP is two years from the date of its issuance, renewable for a new two-year period, but not exceeding a total of four years for the exploration of non-metallic minerals or six years for metal exploration.
