delivered the Opinion of the Court.
We granted certiorari to review the decision of the court of appeals in
O’Brien v. Village Land Company,
I.
On September 9, 1981, Village Land Company (Village Land) purchased from Albert Bloom, the personal representative of the Estate of Jennie Ogren, a 380-acre tract of land located in Boulder County, Colorado, for the sum of $850,000. A personal representative’s deed containing a detailed descriрtion of the property was executed on September 9, 1981, and was duly recorded in the Boulder County Clerk and Recorder’s office on the following day. The Ogren Estate-Village Land deed contained the following provision:
RESERVING an undivided one-half interest in and to all oil, gas and other minerals (except sand, gravel and associated minerals) for a period ending 25 years after the date of this deed or at such time as any ongoing extraction or production of oil, gas or minerals occurring on the proрerty on the 25th anniversary has ceased, whichever is later.
On the same day on which Village Land acquired title to the 380-acre tract of land from the Ogren Estate, Village Land conveyed out of the 380-acre tract a sixty-acre parcel by general warranty deed to G.B. Henderson, who is now deceased, for the sum of $120,000. The granting clause of the Village Land-Henderson deed stated that Village Land was conveying the sixty acres together with “all and singular the hereditaments and appurtenances thereto bеlonging, or in any wise appertaining, ... and all the estate, right, title, interest, claim and demand whatsoever of [Village Land] ... in and to the above bargained premises.” The deed also contained the following reservation:
RESERVING an undivided one-half interest in and to all oil, gas and other minerals (except sand and gravel and associated minerals) for a period ending 25 years after the date of this deed or at such time as any ongoing extraction or production of oil, gas or minerals occurring on the property on the 25th anniversary has ceased, whichever is later.
The warranty clause of the Village Land-Henderson deed stated that Village Land was “well seized of the premises above conveyed ... in fee simple” with full power to convey, and further provided, as pertinent here, that the property was free of all encumbrances “EXCEPT easements and rights-of-way of record and all leases whatsoever of record and special use permits, restrictive covenants and any and all other items аnd agreements of record.” The Village Land-Henderson deed was also recorded in the Boulder County Clerk and Recorder’s Office on the following day a few minutes after the recording of the Ogren Estate-Village Land deed.
Sometime in 1982, after Village Land’s conveyance to Henderson, Vessels Oil and Gas Company began oil and gas production on the sixty-acre tract of land deeded to Henderson. Based on the reservation clause in the Village Land-Henderson deed, Vessels Oil made royalty paymеnts to Village Land. Henderson was not aware of these payments until $16,000 in royalties had been paid to Village Land, at which time Henderson, and later the personal representatives of his estate, directed several requests to Village Land to refund the royalties paid by Vessels Oil. Village Land refused such requests, claiming that it was the rightful owner of the mineral interests
On March 31, 1986, the personal representatives of the Henderson Estate filed suit against Village Land. Claiming that the reservation in the Village Land-Henderson deеd was the result of a mutual mistake, the Henderson Estate requested that the Village Land-Henderson deed be reformed to make clear that Village Land conveyed to Henderson all of the sixty-acre parcel except one-half of the mineral interests reserved in the Ogren Estate-Village Land deed, and further requested that the $16,000 in royalties paid to Village Land be refunded to the Henderson Estate on the theory of unjust enrichment. Village Land in its answer denied that the Village Land-Henderson deed was the result of a mutual mistake and asserted that the deed was not intended to convey any mineral or royalty interest to Henderson.
The Henderson Estate filed a motion for partial summary judgment, and Village Land filed a cross motion for summary judgment. The district court conducted a hearing on the motions and granted summary judgment in favor of the Henderson Estate. 1 The court ruled that the Village Land-Henderson deed was unambiguous and conveyed to Henderson
the fee simple title to the surface of the real property described thеrein and together with all oil, gas and other minerals, except the reservation by Village Land Company’s immediate predecessor in title (Albert Bloom as the Personal Representative of the Estate of Jennie Ogren, a/k/a Jennie T. Ogren) of ‘an undivided one-half interest in and to all oil, gas and other minerals (except sand and gravel and associated minerals) for a period ending 25 years after the date of this deed or at such time as any on-going extraction or production of oil, gas or minerals occurring on the property on the 25th anniversary has ceased, whichever is later.’
The effect of the district court’s ruling was to grant the Henderson Estate a one-half interest in the minerals on the sixy-acre parcel described in the Village Land-Henderson deed, with the other one-half interest remaining in the Ogren Estate pursuant to the reservation in the Ogren Estate-Village Land deed. Subsequent to this ruling, the Henderson Estate filed a motion for summary judgment on its claim for unjust enrichment. The court granted the motion and entered judgment in favor of the Henderson Estate for $18,597.21, plus interest.
Village Land appealed to the court of appeals, which reversed the judgment. Although the court acknowledged that the Village Land-Henderson deed was unambiguous, the court relied on the technical distinction between an “exception” and a “reservation,” as well as that part of the warranty clause “excepting ... any and all other items and agreements of record,” in resolving the appeal. Remarking that “a reservation, as here, can benefit only the grantor,” the court of appeals then drew upon the terms of the Ogren Estate-Village Land deed in construing the Village Land-Henderson deed and reasoned as follows:
It is axiomatic that a court must construe a deed or other conveyance so as togive force and effect to all of its provisions and terms, so as to make all of its provisions operative_ The conveyance from Ogren [Estate] to Village [Land] is clear, and it left Village [Land] with an undivided one-half interest in the minerals in the entire tract, including the 60-acre parcel at issue here. The Ogren reservation of the other undivided one-half interest in the 380-acre tract is noted in the Village-to-Henderson deed in an exception clause including ‘other items and agreements of record.’
We, therefore, conclude that the conveyance from Village [Land] to Henderson is not ambiguous, and that it reserved to Village [Land] an undivided one-half of its interest in the minerals in the 60-acre parcel, conveying the other undivided one-half of its interest in the minerals to Henderson. This conveyance had the effect of conveying to Henderson one-half of Village [Land’s] one-half interest, or an undivided one-quarter interest in the minerals.

“It is a universally accepted principle of law that when a deed is unambiguous and unequivocal, the intention of the parties thereto must be determined from the deed itself, and extrinsic evidence to alter, vary, explain or change the deed by any such evidence is not permissible.”
Brown v. Kirk,
It is well established that a conveyance of land by general description, without any reservation of a mineral interest, passes title to both the land and the underlying mineral deposits. 3
American Law of Mining
¶ 15.13, at 144 (1982). The Village Land-Henderson deed conveyed to Henderson the sixty-acre tract together with all “hereditaments and appurtenances thereto” and all “right, title, [and] interest” of Village Land in the premises, and expressly reserved only “an undivided one-half interest in and to all oil, gas and other minerals” in the sixty-acre parcel. The deed further provided that Village Land was seized in fee simple of the premises described in the deed and that Village Land had full power and authority to convey those premises free and clear of any encumbrances. The clear and unambiguous terms of the Village Land-Henderson deed demonstrate that Village Land was reserving from the grant one-half, and only one-
III.
In its ruling, the court of appeals placed significant weight on the following two factors: the fact that the Village Land-Henderson deed was cast in terms of a reservation rather than an exception; and the fact that the warranty clause in the Village Land-Henderson deed excepted “any and all other items and agreements of record.” This latter factor, the court of appeals clearly implied, put Henderson on notice of the reservation clause in the Ogren Estate-Village Land deed and thereby limited the interest conveyed by the Village Land-Henderson deed to an undivided one-quarter interest in the minerals. We reject this analysis.
A.
Although historically a distinction has been drawn between an exception, which refers to some part of the property not included in the conveyance and with which the grantor never parts, and a reservation, which has been interpreted as the creation in the grantor of a new right or interest in the premises conveyed,

127 Colo, at 456-57,
B.
Similarly misplaced was the court of appeals’ reliance on that part of the Village Land-Henderson warranty clause which excepted from the warranty “any and all othеr items and agreements of record.” We initially note that when the Village Land-Henderson deed was executed on September 9, 1981, the Ogren Estate-Village Land deed had not been recorded and was not filed of record until the following day. More important to our analysis, however, is the fact that even if Henderson had actual knowledge of the one-half mineral interest reservation in the Ogren Estate-Village Land deed, such knowledge would not have placed Henderson on notice that Village Land was unаble to convey the other one-half mineral interest not previously reserved by Village Land’s predecessor in title. The actual interest conveyed by the plain terms of the Village Land-Henderson deed was within the power of the grantor to convey, and under these circumstances, any actual or constructive knowledge on the part of Henderson of the prior reservation in the Ogren Estate-Village Land deed did not serve to dimmish the interest conveyed to him by the granting clause of the deed — namely, a fee sim-
Moreover, the court of appeals’ analysis fails to distinguish between a granting clause and a warranty clause. The purpose of a granting clause is “to define and designate the estate conveyed.”
Kynerd v. Hulen,
Our conclusion that the Village Land-Henderson deed conveyed to Henderson an undivided one-half mineral interest in the sixty-acre parcel is supported by this court’s decision in
Brown v. Kirk,
We accordingly reverse the judgment of the court of appeals and remand the case to
Notes
. At the summary judgment hearing, the legal theories of the parties were substantially different from their assertions in the complaint and answer. Henderson’s Estate claimed that the deed conveying the sixty-acre parcel to Henderson was unambiguous and conveyed all mineral interests in the land minus the one-half previously reserved by the Ogren Estate. Village Land, on the other hand, asserted that the deed was ambiguous and that, as a result, the court should consider extrinsic evidence for purposes of determining the intent of the parties, and that such extrinsic evidence would establish material issues of fact in dispute. The extrinsic evidence that Village Land requested the court to consider was the Ogren Estate-Village Land deed in which the Ogren Estate reserved one-half of the mineral rights. Because the Ogren Estate-Village Land deed was executed on the same day and almost simultaneously with the Village Land-Henderson deed, Village Land asserted that Henderson was aware of the interest reserved by the Ogren Estate and that the undivided one-half interest reserved by Village Land in the conveyance to Henderson was in addition to the one-half previously reserved by the Ogren Estate. Consequently, according to Village Land, Henderson receivеd no interest in the minerals underlying the sixty-acre parcel.
. In determining whether a deed is ambiguous, a trial court may conditionally admit extrinsic evidence on that issue, but if it is ultimately determined that the document is unambiguous, the conditionally admitted evidence must be stricken.
Pepcol Mfg. Co. v. Denver Union Corp.,
. Several jurisdictions in construing deeds conveying fractional mineral interests with reservation clauses have reached a similar result by applying a rule of law established by the Texas Supreme Court in
Duhig v. Peavy-Moore Lumber Co.,
The complex analysis employed in
Duhig
has been criticized as contrived, especially because, as the opinion statеs, ”[t]he result is that the grantor has breached his warranty, but that he has and holds in virtue of the deed containing the warranty the very interest, one-half of the minerals, required to remedy the breach.”
When you think about this statement you can see that it does not make sense. The deed has been allowed to fully operate; as part of that operation, Duhig got (or kept, if you like) 50% of the minerals, but the warranty is breached. If the warranty warrants what the deed рurports to convey, and the court has construed the deed to convey no mineral interest to the lumber company, how can there be a breach of warranty?
The majority is saying that the deed itself, as properly construed by the court, conveyed no minerals to the lumber company, but because of the warranty in the deed, Mrs. Duhig owes the lumber company 50% of the minerals. This logic simply won’t wash. If the majority had construed the deed correctly, how could there be a breach of warranty? In effect, themajority is saying that the deed does one thing and the warranty warrants another. A warranty guarantees only that which the words of the deed purport to convey. Therefore, the quantum which the words purport to convey must be determined without reference to the warranty.
