Anticipated royalty governs stamp-duty valuation of indeterminate Government mining leases, while dead rent remains only a minimum payment.

For Government mining leases whose value cannot be ascertained at execution, the proviso to Section 26 of the Indian Stamp Act, 1899 requires stamp-duty valuation based on estimated anticipated royalty rather than dead rent alone. Royalty depends on mineral extraction, while dead rent is a fixed minimum linked to leased area; Form K under the Mineral Concession Rules, 1960 adopts anticipated royalty for this purpose. Article 33(a) of Schedule 1-A does not override this lease-specific rule. The 1993 circular, which estimates royalty using the highest applicable basis among stated production, scheduled quantity and dead rent, is consistent with the statutory framework and is not ultra vires.

Issues: (i) Whether stamp duty on a Government mining lease is to be computed on dead rent or anticipated royalty; (ii) Whether the 1993 circular prescribing estimation of royalty for stamp-duty purposes is invalid.

Issue (i): Whether stamp duty on a Government mining lease is to be computed on dead rent or anticipated royalty.

Analysis: Section 26 of the Indian Stamp Act, 1899 applies where the value of an instrument's subject matter cannot be ascertained at execution. Its mining-lease proviso specifically permits stamp duty to be assessed on royalty estimated as likely to be payable to the Government. Royalty varies with the quantity of mineral extracted, whereas dead rent is a fixed minimum payment determined by the leased area. Form K under the Mineral Concession Rules, 1960 expressly adopts anticipated royalty for stamp-duty purposes. Article 33(a) of Schedule 1-A did not displace this statutory lease stipulation.

Conclusion: Stamp duty is payable on anticipated royalty estimated in accordance with the mining-lease proviso, and not solely on dead rent. This issue is decided against the assessee.

Issue (ii): Whether the 1993 circular prescribing estimation of royalty for stamp-duty purposes is invalid.

Analysis: The circular requires the highest applicable basis among the production quantities stated in the application, the prescribed schedule quantity, and dead rent for estimating royalty. It does not make dead rent the exclusive measure. The estimation mechanism accords with Section 26 of the Indian Stamp Act, 1899 and the statutory Form K lease terms.

Conclusion: The 1993 circular is not ultra vires. This issue is decided against the assessee.

Final Conclusion: The statutory scheme requires valuation of the mining lease for stamp-duty purposes by reference to estimated anticipated royalty, preserving the State's entitlement to duty on the lease's anticipated economic value.

Ratio Decidendi: For a Government mining lease whose value is indeterminate at execution, the specific proviso to Section 26 of the Indian Stamp Act, 1899 governs stamp-duty valuation through estimated anticipated royalty; dead rent is only a minimum payment and not the exclusive valuation basis.
