SECOND TITLE. Mining Reserves
CHAPTER I. National Mining Reserves
Art. 8.
The Federal Executive shall establish the national mining reserves to which articles 71 and 72 of the Law refers, by means of a decree which must be published in the "Diario Oficial" of the Federation.

For any incorporation of a substance to national mining reserves, the Council must previously carry out a study on the mining potential of that substance in national territory, its importance in the economic development of the country and the national and international offer and demand.

Zones shall be incorporated into national mining reserves only for the purpose of satisfying the future necessities of the country. The parastatal mining entities must previously carry out their exploration by means of assignment, determine with precision the mining potential of the zone and justify its incorporation based on the conditions and perspectives of the national and international market.

The corresponding decree must contain sufficient information to justify the incorporation of the substance or zone, and in the latter case, to determine its localization and extension. It shall also stipulate the group to which the reserve corresponds in accordance with article 72 of the Law.

The Secretary may hand down provisional decrees for the incorporation of substances or zones to national mining reserves, which must be ratified by the Federal Executive within the period stipulated in article 71, final paragraph, of the Law. Such ratification must be published in the "Diario Oficial" of the Federation within the period referred to, and if this ratification is not published within that period, the provisional decree shall not take effect and the land shall become free the day following the expiration of such period.

Art. 9.
The following may not be incorporated into national mining reserve zones intended for exploration or exploitation:

I. Substances to which article 72, items II and III of the Law alludes, or

II. Substances not incorporated into national mining reserves in any of national territory.

Zones in which the object does not prevail or in which the suppositions of their incorporation cease to exist must be disincorporated.

When substances of national mining reserves are disincorporated, the special allotments and concessions which have been granted to aid their exploration or exploitation shall be substituted by ordinary allotments or concessions with the same term of contract as the special ones from which they arose had. The obligations consigned in the special allotment agreement or concession title which are additional to those proper to ordinary allotments or concessions shall become ineffective.

The Federal Executive shall issue the decrees of change of classification or of disincorporation of substances or zones in national mining reserves, which must be published in the "Diario Oficial" of the Federation.

Art. 11.
When the Secretary considers it convenient to promote the approval of mining resources of the national he may convene a meeting for the exploration or exploitation of substances incorporated into national mining reserves.

THIRD TITLE. Mining Allotments and Concessions
CHAPTER I. General Provisions (Title III)
Art. 17.

Art. 18.
In the case of minerals or substances which constitute deposits whose nature is distinct from the components of the lands or products derived from the decomposition of the rocks whose exploitation necessitates subterranean works, not cited by article 3 of the Law, the Federal Executive shall confirm that they are concessionable substances by means of a decree which must be published in the "Diario Oficial" of the Federation.

Whoever is to carry out the exploration, exploitation or benefit of said minerals, substances or products based on the rights of legally acquired ownership or possession, shall have a right of preference to obtain the corresponding mining concession, provided and when they request it in the terms of the Law and of this Regulation, within 120 calendar days following the publication mentioned in the preceding paragraph, and certify that circumstance.

I. For substances to which article 4 of the Law refers, and

II. For products derived from the decomposition of rocks, when their exploitation does not necessitate subterranean works.

Agreements of mining allotment or concession titles shall not confer any right when it is proved that at the time of presentation of the petition, above-ground works of exploitation for the obtainment of substances not subject to the application of the Law were being carried out on the land which is the object of such contracts or titles. Such proof shall be effected in the terms and conditions provided by article 136 of this Regulation, upon petition of the interested party.

The mining allotments must satisfy the requirements of process and have the same duration, rights and obligations as mining concessions, except that the rights derived from the same shall be non-transferrable and may not be the object of any encumbrance.

Art. 23.
When the Council plans to carry out works of exploration on lands which are not free, it shall notify the Secretary of the object and nature of the works, the procedure or system for executing them, the substances which are the reason for the exploration, the program of the works and the effect of the same on pre-existing allotments or concessions. The Secretary shall transfer by mail the above notification to the assignee or concessionaire, who shall manifest the following within a period of 15 working days:

When the holder of the pre-existing allotment or concession proves his technical and economic capacity in exercise of the right of preference, the Secretary shall authorize him to execute the works of exploration, through execution, by direct adjudication, of the respective work contract with the Council.

Art. 24.
If petitions of allotment are presented simultaneously on the same land and substance, the parastatal mining entity whose specific purpose is the exploitation of that substance shall have a preferential right of authorization of the allotment, and, in the absence of such specific purpose, the preferential right shall go to the entity that presents better technical and economic conditions.

If the substances which are the objects of simultaneous petitions are different, and the requirements of co-existence stipulated in article 20 of the Law are fulfilled, both exploitations shall be authorized, subject to that which is provided by articles 48 to 50 of this Regulation.

III. It is expressly stipulated in the contract that the rights to the exploitation which the partner contributes shall not be transmitted in ownership to the private party and that the allotment which is covered thereby cannot be the object of any encumbrance.

IV. The compensation of the partner for the contribution of the rights to the exploitation which shall be agreed upon, shall not be less than 2.5% or more than 3% of the invoice or liquidation value of the mineral which shall be obtained.

Any petition for a mining concession of exploration must be presented directly by any person, and shall be registered before the administrative unit responsible for its receipt in the act of its presentation, the day and hour of its presentation, as well as its progressive registration number being recorded in the body of the same.

When two or more persons try to present petitions simultaneously, an act mentioning that circumstance shall be filed, as well as a report of those petitions and the signatures of the interested parties and of the head of the mentioned unit. The following act shall be registered with the same date and hour.

If he obtains a favorable resolution, the Secretary must issue a new title only for the remaining surface area.

Art. 36.
If upon determination of the freedom of a land, two or more petitions include totally or partially the same portion of land, and the petitions were registered simultaneously, the following shall proceed:

I. The titles for the free portion of each petition shall be issued.

II. The Secretary shall order a summons to the petitioners whose lots totally or partially include the same portion of land, in order that they shall be present before the unit receiving the petitions on the day and hour which he shall indicate to them, for the purpose of drawing lots to determine the petitioner in whose favor the disputed portion shall be given.

III. Once the day and hour is fixed for the drawing, said unit shall verify the assistance of the petitioners or of their duly accredited representatives, and if they do not assist, they shall lose their rights.

IV. That unit shall carry out the drawing and the procedure shall be concluded if the favored petition covered all the disputed land.
