Unexplained oozing statue

The statue of the Risen Christ was placed behind St. James Church sometime around 1998. A watery like substance has been seeping or oozing from the right knee area of this statue since the time around the 20th anniversary of the apparitions. I am unaware of any study done to test this substance and I am not sure if this has been a steady flow since 2001 or an intermittent flow. I can attest to the fact that I was there in November 2004 and November 2005, each time for at least one week, and the substance oozed from the knee, day and night, the whole time I was there. From what I have read, neither the weather nor the time of year seems to have any effect on the seeping substance. It seeps steadily. Is it miraculous? We don't know, but who can explain it? Certainly God can do anything.
