Actually, you don't need to save anything to a temporary file at all. You can use the .AddFromString method of the destination module to add the string value of the source. Try the following code:

Sub CopyModule()
    Dim SourceVBProject As VBIDE.VBProject, DestinationVBProject As VBIDE.VBProject
    Set SourceVBProject = ThisWorkbook.VBProject
    Dim NewWb As Workbook
    Set NewWb = Workbooks.Add ' Or whatever workbook object you have for the destination
    Set DestinationVBProject = NewWb.VBProject
    '
    Dim SourceModule As VBIDE.CodeModule, DestinationModule As VBIDE.CodeModule
    Set SourceModule = SourceVBProject.VBComponents("Module1").CodeModule ' Change "Module1" to the relevsant source module
    ' Add a new module to the destination project
    Set DestinationModule = DestinationVBProject.VBComponents.Add(vbext_ct_StdModule).CodeModule
    '
    With SourceModule
        DestinationModule.AddFromString .Lines(1, .CountOfLines)
    End With
End Sub

Should be self-explanatory! The .AddFomString method simply takes a string variable. So in order to get that, we use the .Lines property of the source module. The first argument (1) is the start line, and the second argument is the end line number. In this case, we want all the lines, so we use the .CountOfLines property.
