The expert group tasked with examining the grounds of the former mother and baby home in Tuam, Co Galway, has warned that identifying human remains found there will be complicated.
The group said it is probable that juvenile remains have become intermixed and this is a "significant complication" to identifying individuals.
The group has also told the Minister for Children this complication is more "acute in the case of juvenile human remains due to their fragile nature, compounded by the potentially significant quantities involved".
Minister Katherine Zappone has been told too that there is no international precedent for this work and the co-operation of all government agencies will be required to ensure the dignity of the human remains is respected.
The Department of Children released the information this evening and promised a monthly update on Tuam going forward.
The Department confirmed that further non-invasive geophysical surveys are to take place on the Tuam site beginning on 17 July.
The Department said these surveys may help identify any further burials.
