ORDER *

Steven David Montague seeks to appeal the district court’s denial of his Federal Rule of Civil Procedure 60(b) motion challenging the court’s earlier denial of his motion under 28 U.S.C. § 2255 to vacate, set aside, or correct his criminal sentence. We deny a certificate of appealability (“COA”) and dismiss the appeal.

The facts underlying Montague’s conviction are set forth in United States v. Montague, 421 F.3d 1099, 1100-01 (10th Cir. 2005), and will not be restated here. When he sought relief under § 2255, the district court denied the motion because it was untimely, among other reasons. On appeal, this court held that the § 2255 motion was not time-barred, but that a COA was not warranted because Montague’s other claims had no merit. United States v. Montague, 260 Fed.Appx. 60, 63 (10th Cir.), cert. denied, — U.S. -, 129 S.Ct. 131, 172 L.Ed.2d 100 (2008).

More than a year later, Montague filed a motion under Rule 60(b)(4) and (6), in which he (1) argued that the district court’s erroneous ruling on timeliness caused the court to fail to rule on his § 2255 claims and his new evidence, and (2) set forth two grounds for challenging *895 his conviction and sentence. The district court correctly characterized the motion as a “mixed” motion asserting both “true” Rule 60(b) arguments, which do not require this court’s authorization to proceed, and second or successive § 2255 claims, which do require authorization under § 2255(h). See Spitznas v. Boone, 464 F.3d 1213, 1217 (10th Cir. 2006). The court denied the 60(b) arguments and dismissed the other claims for lack of jurisdiction. See In re Cline, 531 F.3d 1249, 1252 (10th Cir. 2008). Montague now seeks to appeal the denial of the 60(b) arguments. He does not challenge the dismissal of the unauthorized successive § 2255 claims.

Montague requires a COA to appeal the denial of his 60(b) arguments. See 28 U.S.C. § 2253(c)(1)(B); Spitznas, 464 F.3d at 1217-18. A COA may issue “only if the applicant has made a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2). In this context, to obtain a COA a movant must show “that jurists of reason would find it debatable whether the petition states a valid claim of the denial of a constitutional right and that jurists of reason would find it debatable whether the district court was correct in its procedural ruling.” Spitznas, 464 F.3d at 1225 (quotation omitted). This court reviews the denial of a Rule 60(b)(6) motion for abuse of discretion, and the denial of a Rule 60(b)(4) motion de novo. See Amoco Oil Co. v. U.S. Envtl. Prot. Agency, 231 F.3d 694, 697 (10th Cir. 2000).

In this case, we need look no farther than the second part of the COA test. For substantially the reasons stated in the district court’s Memorandum Decision and Order dated March 31, 2009, we are not convinced that reasonable jurists would find it debatable whether the district court abused its discretion in denying Montague’s Rule 60(b)(6) arguments or erred in denying relief under Rule 60(b)(4).

The motions to proceed without prepayment of fees are GRANTED. A certificate of appealability is DENIED and the appeal is DISMISSED.
