Right. See related questions.
Montanas nickname is the treasure state and it got its nickname from its extensive mineral reserves.
Right. Mexico is one of the largest producers of oil in the world.
Not sure if this is a math/ statistics question. Reserves are assets you hold, but are not using immediately. There are oil reserves, mineral reserves (like gold reserves) and cash reserves. I think you need to rephrase the question for a proper answer.
In your deed you add the following phrase Grantor reserves all mineral interest or excepting all mineral interest

On the Mexican Oil Expropriation in 1938, Mexican President Lazaro Cardenas declared that all mineral and oil reserves found within Mexico belonged to the government, following the principle stated in the 1917 constitution.

Mineral reserves are currently economically feasible. Mineral resources are currently or potentially economically feasible. They both answer the question 'how much is left?' and they seek this answer with geologic and economic considerations. Reserves can be viewed as a subset of resources. The McKelvey Box simplifies this difference by identifying economic feasibility and geologic certainty. The box consists of (from top to bottom, then right to left) reserves, marginal reserves, and demonstrated sub economic resources. Again, reserves are economically extractable at present. Marginal reserves are reserves if economic conditions change, and demonstrated sub economic resources exhibit data to show that the reserves are actually there. On the second column of the chart lie hypothetical resources which are undiscovered, but in known mining districts. And in the last column or section, there are speculative resources which are undiscovered and geologically favorable to exploration.
Venezuela, Mexico, and Brazil qualify as such:Proven oil reserves (2014) in millions of barrels:Venezuela: 297,570 (largest reserves in the world)Brazil: 13,986 (15th)Mexico: 10,264 (16th)Oil production (2013) in millions of barrels per dayVenezuela: 3.02 (9th largest producer in the world)Mexico: 2.93 (10th)Brazil: 2.6 (12th)
Any increase would be due to discoveries and cost-effective discoveries in mineral resource retrievability.
Oil is the most-known mineral fuel.
