To put it simply, it is unlikely that the value of silver/ounce would ever pass the value of gold/ounce. That isn’t to say it is impossible, but it would take some extreme events and conditions to warrant such a milestone.
Now, silver outpacing gold in their respective increases on the price charts is absolutely possible. In fact, some experts believe silver could hit a 9-year high of $30/ounce in 2023, which would set it up to outpace gold prices. This expectation is based on a few factors, namely the current low supply of silver and its tendency to outperform gold during times of high inflation.
