Certain lies are acceptable per Watchtower. Where can I find that?
Watchtower has defined certain circumstances where it's permissible to withhold certain facts, even telling an untruth. Like some outsider, or enemy, may not be deserving to know certain factual answers.
Where can I find such quotations?
From this older thread, the OP has some good quotes:
Jacksons comments at the Australian Royal Commission.
"The faithful witness does not commit perjury when testifying. His testimony is not tainted with lies. However, this does not mean that he is under obligation to give full information to those who may want to bring harm to Jehovah's people in some way. The patriarchs Abraham and Isaac withheld facts from some who did not worship Jehovah. (Genesis 12:10-19; 20:1-18; 26:1-10) Rahab of Jericho misdirected the king's men. (Joshua 2:1-7) Jesus Christ himself refrained from divulging total information when doing so would have caused needless harm. (John 7:1-10) He said: "Do not give what is holy to dogs, neither throw your pearls before swine." Why not? So that "they may never . . . turn around and rip you open."—Matthew 7:6."

I can't copy and paste, but this blog references June 15, 2009 Watchtower, 'Speak Truth with your Neighbor', para. 6. http://thejehovahswitnesses.org/theocratic-warfare-quotes.php
Thanks, Talesin, for what appear to be substantive sources.
See the new definition of lying on page 5 of the 2016 WT no 1:
"Saying something false to someone who is entitled to know the truth."
So the converse is also true. It is not a lie if you say something false to someone who is not entitled to know the truth.
First 2 sentences under the definition of "Lie" from the Insight Book (published 1988):
The opposite of truth. Lying generally involves saying something false to a person who is entitled to know the truth and doing so with the intent to deceive or to injure him or another person.
And then later on:
While malicious lying is definitely condemned in the Bible, this does not mean that a person is under obligation to divulge truthful information to people who are not entitled to it.
