The historically identified potential at Hartford analogous to the results seen from the recently defined 2023 MRE at Plymouth 

The Plymouth Deposit historically was estimated at 51,000,000 tonnes; 13.3% Fe and 10.9% Mn by a 23 DDH between 1954 and 1957 (Table to the right).  In 2023, the updated NI 43-101 resource report estimated the total resource at 74,400,000 tonnes at 13.61% Fe and 10.02% Mn at a 4.75% cutoff grade (previous page). The North and South Hartford deposits were mapped in 1957 and each one was estimated at 50,000,000 tonnes with a grade of 12% Fe and 8% Mn (Table to the right). These historical non-43-101 compliant estimates were based on a 13 DDH drilling program on the North Hartford Deposit and a 9 DDH drilling program done between 1954 and 1957 (Sidwell, 1957).

Currently there are no NI 43-101 technical reports on either one of the Hartford deposits.

In 2023, CDMN plans to continue a more extensive drilling project on the North Hartford Deposit, detailing the size and shape of the deposit and in turn produce a NI 43-101 Resource Report for North Hartford. Plans are also in the works to remap the 1954 gravimetric anomalies using modern gravimetric surveying equipment and determine possible drilling targets southwest of the Plymouth and Hartford Deposits.
