Ok. Sorry for the delay, I have sick people to deal with. I will get this looked up tomorrow.
In the meantime, try here, it's a start:

Edit:
NRS 125.460 State policy. The Legislature declares that it is the policy of this State:
1. To ensure that minor children have frequent associations and a continuing relationship with both parents after the parents have become separated or have dissolved their marriage; and
2. To encourage such parents to share the rights and responsibilities of child rearing.

This is a good sign.
NRS 125.465 Married parents have joint custody until otherwise ordered by court. If a court has not made a determination regarding the custody of a child and the parents of the child are married to each other, each parent has joint legal custody of the child until otherwise ordered by a court of competent jurisdiction.
(Added to NRS by 1993, 1425)
Right here is a big one - Were/are you guys married? Has sole custody been legally ordered for the other parent by the court system? You don't make it sound like it has. And if no legal order has been made, and Nevada is solely handling this case, then you have de-facto partial custody of the child, and a legal right to see her. They can't stop you unless it's been specifically court ordered.
NRS 125.490 Joint custody.
1. There is a presumption, affecting the burden of proof, that joint custody would be in the best interest of a minor child if the parents have agreed to an award of joint custody or so agree in open court at a hearing for the purpose of determining the custody of the minor child or children of the marriage.
2. The court may award joint legal custody without awarding joint physical custody in a case where the parents have agreed to joint legal custody.
3. For assistance in making a determination whether an award of joint custody is appropriate, the court may direct that an investigation be conducted.
(Added to NRS by 1981, 284)—(Substituted in revision for NRS 125.136)
The state assumes that a relationship with both parents is beneficial to the child (right on!) and would essentially prefer that both parents have contact. If you feel you are in a position to do so, an investigation can absolutely be conducted to determine your eligibility. If you are just looking for visitation, and not actual physical partial custody, you really shouldn't have a rough time.
