I never seen \multispan before. But this seems to work:
\definemathmatrix
[determinant]
[matrix:bars]
[simplecommand=thedeterminant]
\starttext
\startformula
\startdeterminant
\NC a_{11} \NC a_{12} \NC a_{13} \NC \cdots \NC a_{1n}\NR
\NC a_{21} \NC a_{22} \NC a_{23} \NC \cdots \NC a_{2n}\NR
\NC a_{31} \NC a_{32} \NC a_{33} \NC \cdots \NC a_{3n}\NR
\HF\NR
% \multispan{9}{\dotfill}\NR
\NC a_{n1} \NC a_{n2} \NC a_{n3} \NC \cdots \NC a_{nn}\NR
\stopdeterminant
\stopformula
\stoptext
I hope it gives you what you want.
