In Iron Silver Mining Company v. Cheesman & Another, the United States Supreme Court was asked to decide whether a mining company had the right to mine on land that was owned by another party. The mining company had obtained a patent from the United States government for the land in question, but the other party claimed that they had a prior right to the land. The Court held that the mining company had the right to mine on the land, as the patent was valid and the other party had no prior right to the land. The Court noted that the patent was issued in accordance with the laws of the United States, and that the other party had no legal basis for their claim. The Court also noted that the mining company had taken all necessary steps to ensure that their rights were protected, and that the other party had failed to do so. In conclusion, the Court held that the mining company had the right to mine on the land, and that the other party had no prior right to the land. The Court also noted that the mining company had taken all necessary steps to ensure that their rights were protected, and that the other party had failed to do so.

In Iron Silver Mining Company v. Cheesman & Another, the Supreme Court was asked to decide whether a mining company had the right to mine on land that it had purchased from another party. The majority opinion held that the mining company did not have such rights because they were not included in their purchase agreement with the other party. Justice Field dissented, arguing that while there may be no express contract between them granting these rights, they should still exist by implication of law and equity due to their long-standing use of this land for mining purposes prior to its sale. He argued further that if these implied rights are denied then it would effectively render all existing contracts concerning mines void since none explicitly grant such privileges either way. Therefore he concluded that under both common law and equity principles, Iron Silver Mining Company should be allowed access to mine on this property as part of their purchase agreement with Cheesman & Another even though those terms do not expressly state so.
